Intel Wired LAN Driver Updates 2015-08-18

This series contains updates to igb, e100, e1000e and ixgbe.

Shota Suzuki provides a fix for a possible overflow in
igb_set_interrupt_capability() which leads to an oops.  When changing the
number of queues by "ethtool -L", set IGB_FLAG_QUEUE_PAIRS in the same
manner as when initializing the igb driver.

Vasily Averin provides a fix for a missing rtnl_unlock() for when we
error out due to not being able to allocate memory for our queues.

Stefan Assman provides a couple of fixes for igb/igbvf.  First changes
the igb driver in probe to simply call igb_enable_sriov() instead of
igb_sriov_reinit() since we are starting from scratch.  Then in igbvf,
fix the driver where it does not clear the buffer_info->dma in all
cases after calling dma_unmap_single(), which was found by changing the
MTU twice.

Richard Cochran implements the periodic output function using the
programmable clock outputs available in i210 when possible, falling
back to the target time for longer periods.

Todd adds support for the Marvell PHY 1512 which is required for i354
devices.  Then updates igb to make sure SR-IOV init uses the correct
number of queues, since recent changes could result in the PF holding
onto all of the queues.

Alex Williamson provides a fix in the case where a guest OS does not
support hot-unplug, so disable SR-IOV prior to unregister_netdev() to
avoid the problem.

Jia-Ju Bai provides several patches, first knocks some collecting dust
off an old e100 driver to add a check to avoid a null pointer
dereference.  Then cleans up a possible resource leak by releasing the
skb buffer allocated when the e100_xmit_prepare() runs into an issue
in the DMA mapping.  In igb, add a missing rtnl_unlock() for when we
error out due to igb_sriov_reinit() in the igb_init_interrupt_scheme().
Provides a e1000e fix, based on suggestions from Alex Duyck to move
head/tail register writing to e1000_configure_tx/rx() to avoid a
possible null pointer dereference (similar to igb driver).  Lastly,
fix a possible memory leak in igb_probe(), where the memory shadow_vfta
allocated by kcalloc in igb_sw_init() is not freed.

Mark simplifies port-specific macros for ixgbe by eliminating explicit
comparisons with 0 and enclose formal parameters in parens to eliminate
the risk of an operator precedence issue.

====================
vrf: a few simplifications and cleanups

These patches remove some unnecessary checks (patches 3, 4), unnecessary
num_slaves member and refcnt manipulations which are already done by the
upper functions.

      vrf: simplify the netdev notifier function · 58aa9087
      Nikolay Aleksandrov authored 
      We can drop the check because if vrf_ptr is present then we must have
the vrf device as a master and since we're running with rtnl it can't go
away.

      vrf: don't check for dstats and rth in uninit path · 3a4a27d3
      Nikolay Aleksandrov authored 
      dstats and rth are always present because we fail the device registration
if they can't be allocated in vrf_init() (ndo_init) so drop the unnecessary
checks.
