Subject: [iwl-next v1 0/4] ixgbe: support MDD events

Hi,

This patchset is adding support for MDD (malicious driver detection) for
ixgbe driver. It can catch the error on VF side and reset malicious VF.

An MDD event can be triggered for example by sending from VF a TSO packet
with segment number set to 0.

Add checking for Tx hang in case of MDD is unhandled. It will prevent VF
from staying in Tx hang state.

Radoslaw Tyl (1):
  ixgbe: turn off MDD while modifying SRRCTL

  ixgbe: add Tx hang detection unhandled MDD
