Misc. fix for cxgb4 and iw_cxgb4
This patch series adds support to enchance error reporting, log detailed
warning for negative advice, support query_qp verb and advertise correct
device max attributes for iwarp.
The patches series is created against 'net-next' tree.
And includes patches on cxgb4 and iw_cxgb4 driver.
Since this patch-series contains changes which are dependent on commit id
4c2c5763 ("cxgb4/iw_cxgb4: use firmware ord/ird resource limits") of net-next
tree we would like to request this patch series to get merged via David Miller's

af_iucv: avoid path quiesce of severed path in shutdown()
An af_iucv stress test showed -EPIPE results for sendmsg()
calls. They are caused by quiescing a path even though it has
been already severed by peer. For IUCV transport shutdown()
consists of 2 steps:
(1) sending the shutdown message to peer
(2) quiescing the iucv path
If the iucv path between these 2 steps is severed due to peer
closing the path, the quiesce step is no longer needed.

====================
Netfilter updates for net-next
The following patchset contains updates for your net-next tree,
they are:
1) Use kvfree() helper function from x_tables, from Eric Dumazet.
2) Remove extra timer from the conntrack ecache extension, use a
workqueue instead to redeliver lost events to userspace instead,
from Florian Westphal.
3) Removal of the ulog targets for ebtables and iptables. The nflog
infrastructure superseded this almost 9 years ago, time to get rid
of this code.
4) Replace the list of loggers by an array now that we can only have
two possible non-overlapping logger flavours, ie. kernel ring buffer
and netlink logging.
5) Move Eric Dumazet's log buffer code to nf_log to reuse it from
all of the supported per-family loggers.
6) Consolidate nf_log_packet() as an unified interface for packet logging.
After this patch, if the struct nf_loginfo is available, it explicitly
selects the logger that is used.
7) Move ip and ip6 logging code from xt_LOG to the corresponding
per-family loggers. Thus, x_tables and nf_tables share the same code
for packet logging.
8) Add generic ARP packet logger, which is used by nf_tables. The
format aims to be consistent with the output of xt_LOG.
9) Add generic bridge packet logger. Again, this is used by nf_tables
and it routes the packets to the real family loggers. As a result,
we get consistent logging format for the bridge family. The ebt_log
logging code has been intentionally left in place not to break
backward compatibility since the logging output differs from xt_LOG.
10) Update nft_log to explicitly request the required family logger when
needed.
11) Finish nft_log so it supports arp, ip, ip6, bridge and inet families.
Allowing selection between netlink and kernel buffer ring logging.
12) Several fixes coming after the netfilter core logging changes spotted
by robots.
13) Use IS_ENABLED() macros whenever possible in the netfilter tree,
from Duan Jiong.
14) Removal of a couple of unnecessary branch before kfree, from Fabian
Frederick.

net: print a notification on device rename
Currently it's done silently (from the kernel part), and thus it might be
hard to track the renames from logs.
Add a simple netdev_info() to notify the rename, but only in case the
previous name was valid.

====================
net: print net_device name/state more often
Currently we use net_device->name only if it's the NETREG_REGISTERED
reg_state, otherwise we return "(unregistered device)".
However, we always populate net_device->name on creation, so it's always
available to us for use. The only caveat is that we might have a name like
"eth%d", in which case we cannot use it as it might change in the future.
Also, the net_device might not be NETREG_UNREGISTERED when the function is
called (_UNINITIALIZED, _UNREGISTERING, _RELEASED, _DUMMY), so it's
misleading.
So, a better way would be to always return the dev->name in netdev_name(),
unless it's in the form of "eth%d" or it's empty, then return
"unnamed net_device". This way we'll always return the name in
NETREG_REGISTERED reg_state, and also return it in other states, when
possible.
Also, to be more verbose on non-NETREG_REGISTERED states, add a function
netdev_reg_state(), which returns a string describing the state, and use it
in netdev_printk()-related functions. If the dev is in NETREG_REGISTERED
state then a void string is regurned and, thus, nothing changes.
After these two patches we'll have the same behaviour in the usual cases,
and more verbose in non-standardad/buggy ones.
v2->v3:
Correct the string for _UNINITIALIZED and warn on a bad reg_state,
per Joe Perches's comments.
v1->v2:
As Tom Gundersen suggested, there might be a case when we have an empty
string as a name for a device, so account this also and return "unnamed
device" for that case too.

Neerav adds support to get the port MAC address from firmware and adds

unique ids to the netdev layer.
Jakub Kicinski provides 2 fixes, first fixes i40e to never generate a software
time stamp if the hardware time stamp is provided. Second fixes a race
condition on queueing skb for hardware time by using a simple bit lock to
avoid race conditions and leaking skbs when multiple transmit rings try
to claim time stamping.
Paul does some general cleanup of the driver to remove unneeded spaces,
comments that are no longer valid, and break that will never get touched.
Jacob Keller adds a verbose warning message when the incorrect PF attempts
to control timestamping for a port to which it was not assigned. The primary
intent of this message is to help debugging the reason why the SIOCSHWSTAMP
ioctl has failed and to help narrow the cause of the issue.

In TLB mode if tlb_dynamic_lb is NOT set, slaves from the bond

exclude dead links which are part of the bond. Also if there is a
temporary link event which brings down the interface, packets
hashed on that interface would be dropped too.
This patch fixes these issues and distributes flows across the
UP links only. Also the array construction of links which are
capable of sending packets happen in the control path leaving
only link-selection during the data-path.
One possible side effect of this is - at a link event; all

Hence, reuse Davinci MDIO driver for Keystone 2 and
enable TI networking for Keystone 2 devices.
Also, as part of this series, enable PHY's creation from DT, because
Keystone 2 supports DT boot mode only.
Changes in v2:
- review comments applied.
Keystone 2 compatibility string changed to "ti,keystone_mdio".

net: davinci_mdio: allow to create phys from dt
This patch allows to create PHYs from DT in case
if they are explicitly defined. The of_mdiobus_register() is
used for such purposes.
For backward compatibility, call of_mdiobus_register() only in case
if at least one PHY's child is defined in DT, otherwise rollback to
mdiobus_register().

The similar MDIO HW blocks is used by keystone 2 SoCs as
in Davinci SoCs:
- one in Gigabit Ethernet (GbE) Switch Subsystem
See http://www.ti.com/lit/ug/sprugv9d/sprugv9d.pdf
- one in 10 Gigabit Ethernet Subsystem
