====================
100GbE Intel Wired LAN Driver Updates 2020-05-22

This series contains updates to virtchnl and the ice driver.

Geert Uytterhoeven fixes a data structure alignment issue in the
virtchnl structures.

Henry adds Flow Director support which allows for the redirection on
ntuple rules over six patches. Initially Henry adds the initial
infrastructure for Flow Director, and then later adds IPv4 and IPv6
support, as well as being able to display the ntuple rules.

Bret add Accelerated Receive Flow Steering (aRFS) support which is used
to steer receive flows to a specific queue. Fixes a transmit timeout
when the VF link transitions from up/down/up because the transmit and
receive queue interrupts are not enabled as part of VF's link up. Fixed
an issue when the default VF LAN address is changed and after reset the
PF will attempt to add the new MAC, which fails because it already
exists. This causes the VF to be disabled completely until it is removed
and enabled via sysfs.

Anirudh (Ani) makes a fix where the ice driver needs to call set_mac_cfg
to enable jumbo frames, so ensure it gets called during initialization
and after reset. Fix bad register reads during a register dump in
ethtool by removing the bad registers.

Paul fixes an issue where the receive Malicious Driver Detection (MDD)
auto reset message was not being logged because it occurred after the VF
reset.

Victor adds a check for compatibility between the Dynamic Device
Personalization (DDP) package and the NIC firmware to ensure that
everything aligns.

Jesse fixes a administrative queue string call with the appropriate
error reporting variable. Also fixed the loop variables that are
comparing or assigning signed against unsigned values.
