Merge branch 'master' of git://git.kernel.org/pub/scm/linux/kernel/git/jkirsher/net-queue
Jeff Kirsher says: ==================== Intel Wired LAN Driver Updates 2016-06-29 This series contains fixes to e1000e and ixgbevf. Jarod Wilson's fix for e1000e was a follow-on patch to his previous fix to keep the hardware VLAN CTAG's for receive and transmit in sync, which in turn resolves the original issue, so revert a portion of the original fix. Xin Long noticed that the ret_val needed to be initialized to IXGBE_ERR_MBX, instead of -IXGBE_ERR_MBX. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
