Subject: [iwl-next v3 0/4] ixgbe: support Malicious Driver Detection (MDD)

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.

v2 --> v3: [2]
 * improve patch 1 commit message based on Paul comment

v1 --> v2: [1]
(All from Simon review, thanks)
 * change wqbr variable type in patch 1 to fix -Warray-bounds build
 * fix indend to be done by space to follow existing style (patch 3)
 * move e_warn() to be in one line because it fit (patch 3)
