cxgb4/iw_cxgb4: work request logging feature

This commit enhances the iwarp driver to optionally keep a log of rdma
work request timining data for kernel mode QPs.  If iw_cxgb4 module option
c4iw_wr_log is set to non-zero, each work request is tracked and timing
data maintained in a rolling log that is 4096 entries deep by default.
Module option c4iw_wr_log_size_order allows specifing a log2 size to use
instead of the default order of 12 (4096 entries). Both module options
are read-only and must be passed in at module load time to set them. IE:

modprobe iw_cxgb4 c4iw_wr_log=1 c4iw_wr_log_size_order=10

The timing data is viewable via the iw_cxgb4 debugfs file "wr_log".
Writing anything to this file will clear all the timing data.
Data tracked includes:

- The host time when the work request was posted, just before ringing
the doorbell.  The host time when the completion was polled by the
application.  This is also the time the log entry is created.  The delta
of these two times is the amount of time took processing the work request.

- The qid of the EQ used to post the work request.

- The work request opcode.

- The cqe wr_id field.  For sq completions requests this is the swsqe
index.  For recv completions this is the MSN of the ingress SEND.
This value can be used to match log entries from this log with firmware
flowc event entries.

- The sge timestamp value just before ringing the doorbell when
posting,  the sge timestamp value just after polling the completion,
and CQE.timestamp field from the completion itself.  With these three
timestamps we can track the latency from post to poll, and the amount
of time the completion resided in the CQ before being reaped by the
application.  With debug firmware, the sge timestamp is also logged by
firmware in its flowc history so that we can compute the latency from
posting the work request until the firmware sees it.

cxgb4/iw_cxgb4: use firmware ord/ird resource limits

Advertise a larger max read queue depth for qps, and gather the resource limits
from fw and use them to avoid exhaustinq all the resources.

Design:

cxgb4:

Obtain the max_ordird_qp and max_ird_adapter device params from FW
at init time and pass them up to the ULDs when they attach.  If these
parameters are not available, due to older firmware, then hard-code
the values based on the known values for older firmware.
iw_cxgb4:

Fix the c4iw_query_device() to report these correct values based on
adapter parameters.  ibv_query_device() will always return:

max_qp_rd_atom = max_qp_init_rd_atom = min(module_max, max_ordird_qp)
max_res_rd_atom = max_ird_adapter

Bump up the per qp max module option to 32, allowing it to be increased
by the user up to the device max of max_ordird_qp.  32 seems to be
sufficient to maximize throughput for streaming read benchmarks.

Fail connection setup if the negotiated IRD exhausts the available
adapter ird resources.  So the driver will track the amount of ird
resource in use and not send an RI_WR/INIT to FW that would reduce the
available ird resources below zero.

net: add name_assign_type netdev attribute

Based on a patch by David Herrmann.

The name_assign_type attribute gives hints where the interface name of a
given net-device comes from. These values are currently defined:
  NET_NAME_ENUM:
    The ifname is provided by the kernel with an enumerated
    suffix, typically based on order of discovery. Names may
    be reused and unpredictable.
  NET_NAME_PREDICTABLE:
    The ifname has been assigned by the kernel in a predictable way
    that is guaranteed to avoid reuse and always be the same for a
    given device. Examples include statically created devices like
    the loopback device and names deduced from hardware properties
    (including being given explicitly by the firmware). Names
    depending on the order of discovery, or in any other way on the
    existence of other devices, must not be marked as PREDICTABLE.
  NET_NAME_USER:
    The ifname was provided by user-space during net-device setup.
  NET_NAME_RENAMED:
    The net-device has been renamed from userspace. Once this type is set,
    it cannot change again.
  NET_NAME_UNKNOWN:
    This is an internal placeholder to indicate that we yet haven't yet
    categorized the name. It will not be exposed to userspace, rather
    -EINVAL is returned.

The aim of these patches is to improve user-space renaming of interfaces. As
a general rule, userspace must rename interfaces to guarantee that names stay
the same every time a given piece of hardware appears (at boot, or when
attaching it). However, there are several situations where userspace should
not perform the renaming, and that depends on both the policy of the local
admin, but crucially also on the nature of the current interface name.

If an interface was created in repsonse to a userspace request, and userspace
already provided a name, we most probably want to leave that name alone. The
main instance of this is wifi-P2P devices created over nl80211, which currently
have a long-standing bug where they are getting renamed by udev. We label such
names NET_NAME_USER.

If an interface, unbeknown to us, has already been renamed from userspace, we
most probably want to leave also that alone. This will typically happen when
third-party plugins (for instance to udev, but the interface is generic so could
be from anywhere) renames the interface without informing udev about it. A
typical situation is when you switch root from an installer or an initrd to the
real system and the new instance of udev does not know what happened before
the switch. These types of problems have caused repeated issues in the past. To
solve this, once an interface has been renamed, its name is labelled
NET_NAME_RENAMED.

In many cases, the kernel is actually able to name interfaces in such a
way that there is no need for userspace to rename them. This is the case when
the enumeration order of devices, or in fact any other (non-parent) device on
the system, can not influence the name of the interface. Examples include
statically created devices, or any naming schemes based on hardware properties
of the interface. In this case the admin may prefer to use the kernel-provided
names, and to make that possible we label such names NET_NAME_PREDICTABLE.
We want the kernel to have tho possibilty of performing predictable interface
naming itself (and exposing to userspace that it has), as the information
necessary for a proper naming scheme for a certain class of devices may not
be exposed to userspace.

The case where renaming is almost certainly desired, is when the kernel has
given the interface a name using global device enumeration based on order of
discovery (ethX, wlanY, etc). These naming schemes are labelled NET_NAME_ENUM.

Lastly, a fallback is left as NET_NAME_UNKNOWN, to indicate that a driver has
not yet been ported. This is mostly useful as a transitionary measure, allowing
us to label the various naming schemes bit by bit.

ipv6: addrconf: implement address generation modes

This patch introduces a possibility for userspace to set various (so far
two) modes of generating addresses. This is useful for example for
NetworkManager because it can set the mode to NONE and take care of link
local addresses itself. That allow it to have the interface up,
monitoring carrier but still don't have any addresses on it.

One more use-case by Dan Williams:
<quote>
WWAN devices often have their LL address provided by the firmware of the
device, which sometimes refuses to respond to incorrect LL addresses
when doing DHCPv6 or IPv6 ND.  The kernel cannot generate the correct LL
address for two reasons:

1) WWAN pseudo-ethernet interfaces often construct a fake MAC address,
or read a meaningless MAC address from the firmware.  Thus the EUI64 and
the IPv6LL address the kernel assigns will be wrong.  The real LL
address is often retrieved from the firmware with AT or proprietary
commands.

2) WWAN PPP interfaces receive their LL address from IPV6CP, not from
kernel assignments.  Only after IPV6CP has completed do we know the LL
address of the PPP interface and its peer.  But the kernel has already
assigned an incorrect LL address to the interface.

So being able to suppress the kernel LL address generation and assign
the one retrieved from the firmware is less complicated and more robust.

Network driver for Armada 375 SoC

This is the fourth round of the Armada 375 network support patchset. I've
tried to address all the feedback provided for last version and I hope the
driver looks better now.

If there's nothing else to fix, we'd like to merge this for v3.17. The first
patch should go through the network tree, and the other patches through
the mvebu tree.

Thanks a lot for all the great review, and feel free to comment some more!

Changes from v3:

  * Further optimization of the MTU, MAC and ring parameter change to make
    it smoothier.

  * Lots of cleanups in the parser configuration code, most of them addressing
    the feedback from Francois. This include fixing: missing curly braces,
    excessive parenthesis, excessive scope, and making several functions
    more readable.

  * Removed the Rx/Tx queue number module parameter. There's no reason to
    use any other than the default hardware-defined value.

Changes from v2:

  * Reworked mvpp2_prs_tcam_first_free() as suggested by Joe and Francois,
    to have a single loop instead of two.

  * Replaced mvpp2_cpu_interrupts_enable/disable(pp, cpu) with one function
    that enables/disable interrupts on all the CPUs at once.

  * Factor out Tx descriptor DMA unmap + descriptor put sequence to have
    more readable code, as suggested by Francois.

  * Remove redundant netif_running() checks in the ingress and egress path,
    as suggested by Francois.

  * Reworked ring parameter, MTU and MAC address setting to produce a
    more gentle modification of the parameter, and have a fallback in the
    event of a failure.

  * Fixed a percpu memory leak on error path, also noted by Francois.

  * Removed the usage of the legacy net_device irq field, requested by
    Francois.

  * Removed the unneeded multiple Tx port support. It was hardcoded to a single
    Tx port in the previous version so we decided to drop it and simplify the
    code.

  * Optimize the on_each_cpu() calls to clear the sent counters and the
    TX_DONE pkts coalescing setting. on_each_cpu is expensive so it's better
    to minize the calls to it.

Changes from v1:

  * Marcin Wojtas is the author of the driver, so I fixed authorship
    for patch 1/3:
    "ethernet: Add new driver for Marvell Armada 375 network unit"

This patchset adds a new network driver to support the network controller
in Armada 375 SoC.

The network interfaces share a common hardware unit called Packet Processor,
which contains a common register space and per-port register spaces.

The new network unit has different RXQ and TXQ management. The ports
associate so-called per-port "logical queues" which are mapped to "physical
queues". The latter are shared among the ports.

Fo the egress part, the mapping for each port is predefined by hardware.
The egress path incorporates so-called aggregation queues (one per CPU),
from where the data is passed to the physical queues and then via prefetch
buffer to the TxDMA.

The ingress path has a Parser and Classifier (PnC) and a Buffer Manager (BM)
whose usage is obligatory. We are only implementing a simple configuration
for the Parser and Classifier, yet the code is considerably large.

This network unit has other optional features like xPON, WoL, Hardware
Forwarding, and more. This initial commit doesn't provide support for these.

The mvpp2 network driver has been written by Marcin Wojtas and then reviewed
and cleaned up by Ezequiel Garcia.

Bluetooth: Unify helpers for bdaddr_list manipulations

We already have several lists with struct bdaddr_list entries, and there
will be more in the future. Since the operations for adding, removing,
looking up and clearing entries in these lists are exactly the same it
doesn't make sense to define new functions for every single list. This
patch unifies the functions by passing the list_head to them instead of
a hci_dev pointer.

Bluetooth: Fix enabling Authenticated Payload Timeout Expired event

The Authenticated Payload Timeout Expired event is valid for
controllers with BR/EDR Secure Connections support, but also for
LE only controllers supporting LE Ping feature. When either of them
is available enable this event. Previous it was not enabled when
the controller was only supporting LE operation.
