7c5365bca3 stmmac: use resource_size()
The size calculation is not correct.  It should be end - start + 1.

52a1dd4d15 igb: cleanup usage of virtualization registers
The igb driver was incorrectly attempting to write to registers that do not
exist on 82580 hardware.  This wasn't causing any issues that I can tell,
but it is not recommended behavior either so I have changed this so we are
determining which registers to write to based on mac type.

411f557c3a igb: Do not overwrite mdicnfg register when accessing 82580 phy
This change removes the extra configuration we were doing on the mdicnfg
register which should be set by EEPROM and which we should not need to
write again afterwards.  This code was a holdover from some earlier
development work that was being done on a board with an incomplete EEPROM
and is no longer needed now that the production EEPROMs are in place.

907cdda520 tcp: Add SNMP counter for DEFER_ACCEPT
Its currently hard to diagnose when ACK frames are dropped because an
application set TCP_DEFER_ACCEPT on its listening socket.

See http://bugzilla.kernel.org/show_bug.cgi?id=15507

This patch adds a SNMP value, named TCPDeferAcceptDrop

netstat -s | grep TCPDeferAcceptDrop
    TCPDeferAcceptDrop: 0

This counter is incremented every time we drop a pure ACK frame received
by a socket in SYN_RECV state because its SYNACK retrans count is lower
than defer_accept value.

b2db756449 ipv6: Reduce timer events for addrconf_verify().
This patch reduces timer events while keeping accuracy by rounding
our timer and/or batching several address validations in addrconf_verify().

addrconf_verify() is called at earliest timeout among interface addresses'
timeouts, but at maximum ADDR_CHECK_FREQUENCY (120 secs).

In most cases, all of timeouts of interface addresses are long enough
(e.g. several hours or days vs 2 minutes), this timer is usually called
every ADDR_CHECK_FREQUENCY, and it is okay to be lazy.
(Note this timer could be eliminated if all code paths which modifies
variables related to timeouts call us manually, but it is another story.)

However, in other least but important cases, we try keeping accuracy.

When the real interface address timeout is coming, and the timeout
is just before the rounded timeout, we accept some error.

When a timeout has been reached, we also try batching other several
events in very near future.

73852e8151 NET_DMA: free skbs periodically
Under NET_DMA, data transfer can grind to a halt when userland issues a
large read on a socket with a high RCVLOWAT (i.e., 512 KB for both).
This appears to be because the NET_DMA design queues up lots of memcpy
operations, but doesn't issue or wait for them (and thus free the
associated skbs) until it is time for tcp_recvmesg() to return.
The socket hangs when its TCP window goes to zero before enough data is
available to satisfy the read.

Periodically issue asynchronous memcpy operations, and free skbs for ones
that have completed, to prevent sockets from going into zero-window mode.

33bd9f601e ixgbevf: Fix VF Stats accounting after reset
The counters in the 82599 Virtual Function are not clear on read.  They
accumulate to the maximum value and then roll over.  They are also not
cleared when the VF executes a soft reset, so it is possible they are
non-zero when the driver loads and starts.  This has all been accounted
for in the code that keeps the stats up to date but there is one case
that is not.  When the PF driver is reset the counters in the VF are
all reset to zero.  This adds an additional accounting overhead into
the VF driver when the PF is reset under its feet.  This patch adds
additional counters that are used by the VF driver to accumulate and
save stats after a PF reset has been detected.  Prior to this patch
displaying the stats in the VF after the PF has reset would show
bogus data.

d11a4dc18b ipv4: check rt_genid in dst_check
Xfrm_dst keeps a reference to ipv4 rtable entries on each

route has changed, is to implement dst_check for this. This is
what ipv6 side does too.

The problems started after 87c1e12b5e
("ipsec: Fix bogus bundle flowi") which fixed a bug causing xfrm_dst
to not get reused, until that all lookups always generated new
xfrm_dst with new route reference and path mtu worked. But after the
fix, the old routes started to get reused even after they were expired
causing pmtu to break (well it would occationally work if the rtable
gc had run recently and marked the route obsolete causing dst_check to
get called).

0ecad5a262 ixgbe: Fix 82599 KX4 Wake on LAN issue after an improper system shutdown
Advanced Power Management is disabled for 82599 KX4 connections by
clearing GRC.APME bit, causing it to not wake the system from an
improper system shutdown. By default GRC.APME is enabled and software
is not supposed to clear these settings during adapter probe.

1097cd1770 ixgbe: Fix 82599 multispeed fiber link issues due to Tx laser flapping
Fix 82599 link issues during driver load and unload test using multi-speed
10G & 1G fiber modules. When connected back to back sometime 82599 multispeed
fiber modules would link at 1G speed instead of 10G highest speed, due to a
race condition in autotry process involving Tx laser flapping. Move autotry
autoneg-37 tx laser flapping process from multispeed module init setup
to driver unload. This will alert the link partner to restart its
autotry process when it tries to establish the link with the link partner
