====================
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.
