Intel Wired LAN Driver Updates 2015-01-22

This series contains updates to e1000, e1000e, igb, fm10k and virtio_net.

Asaf Vertz provides a fix for e1000 to future-proof the time comparisons
by using time_after_eq() instead of plain math.

Mathias Koehrer provides a fix for e1000e to add a check to e1000_xmit_frame()
to ensure a work queue will not be scheduled that has not been initialized.

Jacob adds the use of software timestamping via the virtio_net driver.

Alex Duyck cleans up page reuse code in igb and fm10k.  Cleans up the
page reuse code from getting into a state where all the workarounds
needed are in place as well as cleaning up oversights, such as using
__free_pages instead of put_page to drop a locally allocated page.

Richard Cochran provides 4 patches for igb dealing with time sync.
First provides a helper function since the code that handles the time
sync interrupt is repeated in three different places.  Then serializes
the access to the time sync interrupt since the registers may be
manipulated from different contexts.  Enables the use of i210 device
interrupt to generate an internal PPS event for adjusting the kernel
system time.  The i210 device offers a number of special PTP hardware
clock features on the Software Defined Pins (SDPs), so added support for
two of the possible functions (time stamping external events and
periodic output signals).

Or Gerlitz fixes fm10k from double setting of NETIF_F_SG since the
networking core does it for the driver during registration time.

Joe Stringer adds support for up to 104 bytes of inner+outer headers in
fm10k and adds an initial check to fail encapsulation offload if these
are too large.

Matthew increases the timeout for the data path reset based on feedback
from the hardware team, since 100us is too short of a time to wait for
the data path reset to complete.

Alexander Graf provides a fix for igb to indicate failure on VF reset
for an empty MAC address, to mirror the behavior of ixgbe.

Florian Westphal updates e1000 and e1000e to support txtd update delay
via xmit_more, this way we won't update the Tx tail descriptor if the
queue has not been stopped and we know at least one more skb will be
sent right away.
