====================
Intel Wired LAN Driver Updates

This series contains updates to e1000, e1000e, igb, igbvf, ixgb, ixgbe,
ixgbevf and i40evf.

Mark fixes an issue with ixgbe and ixgbevf by adding a bit to indicate
when workqueues have been initialized.  This permits the register read
error handling from attempting to use them prior to that, which also
generates warnings.  Checking for a detected removal after initializing
the work queues allows the probe function to return an error without
getting the workqueue involved.  Further, if the error_detected
callback is entered before the workqueues are initialized, exit without
recovery since the device initialization was so truncated.

Francois Romieu provides several patches to all the drivers to remove
the open coded skb_cow_head.

Jakub Kicinski provides a fix for igb where last_rx_timestamp should be
updated only when Rx time stamp is read.

Mitch provides a fix for i40evf where a recent change broke the RSS LUT
programming causing it to be programmed with all 0's.
