Intel Wired LAN Driver Updates 2019-11-01

This series contains updates to e1000, igb, igc, ixgbe, i40e and driver
documentation.

Lyude Paul fixes an issue where a fatal read error occurs when the
device is unplugged from the machine.  So change the read error into a
warn while the device is still present.

Manfred Rudigier found that the i350 device was not apart of the "Media
Auto Sense" feature, yet the device supports it.  So add the missing
i350 device to the check and fix an issue where the media auto sense
would flip/flop when no cable was connected to the port causing spurious
kernel log messages.

I fixed an issue where the fix to resolve receive buffer starvation was
applied in more than one place in the driver, one being the incorrect
location in the i40e driver.

Wenwen Wang fixes a potential memory leak in e1000 where allocated
memory is not properly cleaned up in one of the error paths.

Jonathan Neuschäfer cleans up the driver documentation to be consistent
and remove the footnote reference, since the footnote no longer exists in
the documentation.

Igor Pylypiv cleans up a duplicate clearing of a bit, no need to clear
it twice.

v2: Fixed alignment issue in patch 3 of the series based on community
    feedback.
