====================
1GbE Intel Wired LAN Driver Updates 2019-05-28

This series contains updates to e1000e, igb and igc.

Feng adds additional information on a warning message when a read of a
hardware register fails.

Gustavo A. R. Silva fixes up two "fall through" code comments so that
the checkers can actually determine that we did comment that the case
statement is falling through to the next case.

Sasha does some cleanup on the igc driver by removing duplicate
white space and removed a unneeded workaround for igc.  Adds support for
flow control to the igc driver.

Konstantin Khlebnikov reverts a previous fix which was causing a false
positive for a hardware hang.  Provides a fix so that when link is lost
the packets in the transmit queue are flushed and wakes the transmit
queue when the NIC is ready to send packets.
