unregister_netdevice : move RTM_DELLINK to until after ndo_uninit

This patch fixes ordering of rtnl notifications during unregister_netdevice
by moving RTM_DELLINK notification to until after ndo_uninit.

The problem was seen with unregistering bond netdevices.

bond ndo_uninit callback generates a few RTM_NEWLINK notifications for
NETDEV_CHANGEADDR and NETDEV_FEAT_CHANGE. This is seen mostly when the
bond is deleted with slaves still enslaved to the bond.

During unregister netdevice (rollback_registered_many to be specific)
bond ndo_uninit is called after RTM_DELLINK notification goes out.
This results in userspace seeing RTM_DELLINK followed by a couple of
RTM_NEWLINK's.

In userspace problem was seen with libnl. libnl cache deletes the bond
when it sees RTM_DELLINK and re-adds the bond with the following
RTM_NEWLINK. Resulting in a stale bond entry in libnl cache when the kernel
has already deleted the bond.

This patch has been tested for bond, bridges and vlan devices.

net: filter: make register naming more comprehensible

The current code is a bit hard to parse on which registers can be used,
how they are mapped and all play together. It makes much more sense to
define this a bit more clearly so that the code is a bit more intuitive.
This patch cleans this up, and makes naming a bit more consistent among
the code. This also allows for moving some of the defines into the header
file. Clearing of A and X registers in __sk_run_filter() do not get a
particular register name assigned as they have not an 'official' function,
but rather just result from the concrete initial mapping of old BPF
programs. Since for BPF helper functions for BPF_CALL we already use
small letters, so be consistent here as well. No functional changes.

tcp: fix cwnd limited checking to improve congestion control

Yuchung discovered tcp_is_cwnd_limited() was returning false in
slow start phase even if the application filled the socket write queue.

All congestion modules take into account tcp_is_cwnd_limited()
before increasing cwnd, so this behavior limits slow start from
probing the bandwidth at full speed.

The problem is that even if write queue is full (aka we are _not_
application limited), cwnd can be under utilized if TSO should auto
defer or TCP Small queues decided to hold packets.

So the in_flight can be kept to smaller value, and we can get to the
point tcp_is_cwnd_limited() returns false.

With TCP Small Queues and FQ/pacing, this issue is more visible.

We fix this by having tcp_cwnd_validate(), which is supposed to track
such things, take into account unsent_segs, the number of segs that we
are not sending at the moment due to TSO or TSQ, but intend to send
real soon. Then when we are cwnd-limited, remember this fact while we
are processing the window of ACKs that comes back.

For example, suppose we have a brand new connection with cwnd=10; we
are in slow start, and we send a flight of 9 packets. By the time we
have received ACKs for all 9 packets we want our cwnd to be 18.
We implement this by setting tp->lsnd_pending to 9, and
considering ourselves to be cwnd-limited while cwnd is less than
twice tp->lsnd_pending (2*9 -> 18).

This makes tcp_is_cwnd_limited() more understandable, by removing
the GSO/TSO kludge, that tried to work around the issue.

Note the in_flight parameter can be removed in a followup cleanup
patch.

hyperv: Enable sendbuf mechanism on the send path

This is a small supplement for commit e7428e95a06fb516fac1308bd0e176e27c0b9287
("virtio-net: put virtio-net header inline with data"). TCP packages have
enough room to put virtio-net header in, but UDP packages do not. By
setting dev->needed_headroom for virtio-net device, UDP packages could have
enough room.

For UDP packages, sk_buff is alloced in fun __ip_append_data. The size is
"alloclen + hh_len + 15", and "hh_len = LL_RESERVED_SPACE(rt-dst.dev);".
The Macro is defined as follows:
#define LL_RESERVED_SPACE(dev) \
     ((((dev)->hard_header_len+(dev)->needed_headroom)\
     &~(HH_DATA_MOD - 1)) + HH_DATA_MOD)
By default, for UDP packages, after skb is allocated, only 16 bytes
reserved. And 2 bytes remained after mac header is set. That is not enough
to put virtio-net header in. If we set dev->needed_headroom to 12 or 10
(according to mergeable_rx_bufs is on or off ), more room can be reserved.
Then there is enough room for UDP packages to put the header in.

This series contains updates to i40e and i40evf.

Jacob provides a i40e patch to remove ptp_tx_work() because it conflicts
with the interrupt-based handler and will cause spurious warning messages
to be displayed in the kernel log.  Since the hardware can properly trigger
an interrupt, we do not need to poll for an available timestamp in a work
queue any more.

Greg provides two patches for i40e, first to retain the MAC filter list
when changing a port VLAN.  Second fixes an issue where the function to
set the VF MAC address was not taking the port VLAN filter into account
when setting/clearing/resetting the VF's host administered MAC address.

Mitch provides three patches for i40evf, first adds support for getting

of device channels from ethtool.  Fixes a panic that woudl occur in the VF
if the PF driver failed or was removed from the host kernel.

Shannon adds driver version string to the driver version command so that
can be passed down through the firmware to low-level NC-SI functions.

Neerav provides several patches, first redistributes queue vectors after
DCB reconfiguration because the total number of queues that are configured
for a VSI may change based on a change in the total number of TCs enabled
as a result of a change in the DCB configuration based on DCBX.  Second,
allows the driver probe to continue when querying DCB config fails.
Lastly, provides changes to retrieve and store missing link config
information that was not being cached in the struct i40e_link_status.

parameters to remove an argument which is no longer used.

the now partially defunct TOS field. This patch adds two new options as
follows:
   - prio_queueing_skb: bases priority queueing on skb-priority
   - prio_queueing_vlan: uses the priority code point in the 802.1Q header

qeth: Fix default queue setting in priority queueing

The default queue for queueing modes prio_queueing_prec and
prio_queueing_tos is supposed to be QETH_DEFAULT_QUEUE. However, neither
mode will reset the default default_out_queue value when enabled, leaving
a previously set value activate as the default.
E.g. enabling one of the fixed queueing modes, e.g. no_prio_queueing:0,
and successively switching to any of the prio_queueing_* modes will
leave default_out_queue at the previous (wrong) value 0.

i40e: Redistribute queue vectors after DCB reconfiguration

The queue vectors are originally distributed among the total
number of queues that are configured for a given VSI. The number
of queues that are configured for a VSI depends on the number of
TCs that are enabled for the VSI at VSI setup/creation time.

But, the total number of queues that are configured for a VSI may
change based on change in the total number of TCs enabled as a
result of change in DCB configuration based on DCBX.

Hence, it is required for the queue vectors to be redistributed
when the total queues that are configured for a given VSI changes.

Without redistributing the vectors the queues that are configured
for the newly enabled TCs may not be able to do any Tx/Rx.

sched, cls: check if we could overwrite actions when changing a filter

When actions are attached to a filter, they are a part of the filter
itself, so when changing a filter we should allow to overwrite the actions
inside as well.

In my specific case, when I tried to _append_ a new action to an existing
filter which already has an action, I got EEXIST since kernel refused
to overwrite the existing one in kernel.

This patch checks if we are changing the filter checking NLM_F_CREATE flag
(Sigh, filters don't use NLM_F_REPLACE...) and then passes the boolean down
to actions. This fixes the problem above.

Marc Kleine-Budde says:

====================
this is a pull request of 10 patches for net-next/master.

It consists of three patches by Alexander Shiyan, which improve the
mcp251x driver. Stefano Babic's patch move the SPI driver into a sub
folder. The three patches by Olivier Sobrie add support for the Kvaser
Leaf v2 and usb mini PCIe hardware to the existing driver. Alexander
Stein contributes eg20t support to the c_can pci driver. Together with
the patches on the net-tree, we'll be able to remove the pch_can driver
soon. Kurt Van Dijck's two patches clean up the sysfs attributes of the
softing driver.

====================
tipc: add support for link state subscriptions

Low level topology information like TIPC link up/down is useful for
applications like teamd to make smarter failover decisions in a
HA cluster environment. Fetching logical link names through an ioctl
may hurt the eyes of some. Suggestions for a more elegant way of doing
this would be appreciated in that case. :)

v2:
   -Properly based on net-next
   -Off-list comments from Billie Alsup:
    -Add a string length parameter to tipc_node_get_linkname

tipc: add ioctl to fetch link names

We add a new ioctl for AF_TIPC that can be used to fetch the
logical name for a link to a remote node on a given bearer. This
should be used in combination with link state subscriptions.
The logical name size limit definitions are moved to tipc.h, as
they are now also needed by the new ioctl.
