In a configuration with CONFIG_BRIDGE set to 'm' and CONFIG_ROCKER
set to 'y', undefined references occur at link time:

> /home/jim/linux/drivers/net/ethernet/rocker/rocker.c:3016: undefined

This patch fixes these by declaring CONFIG_ROCKER as being dependent

In commit 2b4636a5 ("tcp_cubic: make the delay threshold of HyStart
less sensitive"), HYSTART_DELAY_MIN was changed to 4 ms.

The remaining problem is that using delay_min + (delay_min/16) as the
threshold is too sensitive.

6.25 % of variation is too small for rtt above 60 ms, which are not
uncommon.

Lets use 12.5 % instead (delay_min + (delay_min/8))

Tested:
 80 ms RTT between peers, FQ/pacing packet scheduler on sender.
 10 bulk transfers of 10 seconds :

nstat >/dev/null
for i in `seq 1 10`
 do
   netperf -H remote -- -k THROUGHPUT | grep THROUGHPUT
 done
nstat | grep Hystart

When deploying FQ pacing, one thing we noticed is that CUBIC Hystart
triggers too soon.

Having SNMP counters to have an idea of how often the various Hystart
methods trigger is useful prior to any modifications.

This patch adds SNMP counters tracking, how many time "ack train" or
"Delay" based Hystart triggers, and cumulative sum of cwnd at the time
Hystart decided to end SS (Slow Start)

Our FW can support several fastpath HSI [for backward compatibility] but up
until now VFs were always configured to use latest fastpath HSI [although VF
driver might be older and use an older fastpath HSI].

For linux drivers, the differences are insignificant since driver never
utilized features that were overridden by the HSI change. But for VMs running
other operating systems this might be a problem.
In addition, eventually FW might change fastpath HSI in such a manner that
backward compatibility WILL break unless configured with proper version.

This patch fixes the issue for other operating system VMs, as well as lays
the ground work for forward compatibility in regard to the fastpath HSI.

The comment says that the built-in strncmp didn't work. That is not
surprising, as apparently "str" semantics are not really what is
wanted (hint: de4x5_strncmp only stops when two different bytes are
encountered or the end is reached; not if either byte happens to be
0). de4x5_strncmp is actually a memcmp (except for the signature and
that bytes are not necessarily treated as unsigned char); since only
the boolean value of the result is used we can just replace
de4x5_strncmp with memcmp.

Commit ce1a4ea3 ("net: avoid one atomic operation in skb_clone()")
took the wrong way to save one atomic operation.

It is actually possible to avoid two atomic operations, if we
do not change skb->fclone values, and only rely on clone_ref
content to signal if the clone is available or not.

skb_clone() can simply use the fast clone if clone_ref is 1.

kfree_skbmem() can avoid the atomic_dec_and_test() if clone_ref is 1.

Note that because we usually free the clone before the original skb,
this particular attempt is only done for the original skb to have better
branch prediction.

SKB_FCLONE_FREE is removed.

The commit 56bfa7ee ("unregister_netdevice : move RTM_DELLINK to
until after ndo_uninit") tried to do this ealier but while doing so
it created a problem. Unfortunately the delayed rtmsg_ifinfo() also
delayed call to fill_info(). So this translated into asking driver
to remove private state and then query it's private state. This
could have catastropic consequences.

This change breaks the rtmsg_ifinfo() into two parts - one takes the
precise snapshot of the device by called fill_info() before calling
the ndo_uninit() and the second part sends the notification using
collected snapshot.

It was brought to notice when last link is deleted from an ipvlan device
when it has free-ed the port and the subsequent .fill_info() call is
trying to get the info from the port.

This patch changes the name of vnet_port_alloc_tx_bufs to
vnet_port_alloc_tx_ring, since there are no buffer allocations after
transmit zero copy support was added. This patch also moves the ring
allocation to after VIO version negotiation to allow for
different-sized descriptors in later VIO versions.

====================
ethtool, net/mlx4_en: RSS hash function selection

This patchset by Eyal adds support in set/get of RSS hash function. Current
supported functions are Toeplitz and XOR. The API is design to enable adding
new hash functions without breaking backward compatibility.
Userspace patch will be sent after API is available in kernel.

The patchset was applied and tested over commit cd4c910e ("netpoll: delete
defconfig references to obsolete NETPOLL_TRAP")
