[net-next,00/14,pull,request] 1GbE Intel Wired LAN Driver Updates 2020-04-17

This series contains updates to e1000e and igc only.

Sasha adds partial generic segmentation offload (GSO partial) support to
the igc driver.  Also added support for translating taprio schedules
into i225 cycles in igc.  Did clean up of dead code or unused defines in
the igc driver.  Refactored the code to avoid forward declarations where
possible.  Enables the NETIF_F_HW_TC flag for igc by default.

Vinicius adds support for ETF offloading using the similar approach that
taprio offload used.

Kees Cook fixes a clang warning in the e1000e driver by moving the
declared variable either into the switch case that uses the variable or
lift them up into the main function body, to help the compiler.

Andre fixed some register overwriting when dumping registers via ethtool
for igc driver.  Also fixed support for ethtool Network Flow
Classification (NFC) queue redirection by adding the missing code needed
to enable the queue selection feature from Receive Address High (RAH)
register.  Cleans up code to remove the code bits designed to support
tc-flower filters, since this client part does not support it.

The following are changes since commit 2fcd80144b93ff90836a44f2054b4d82133d3a85:
