From: Dave Ertman <david.m.ert...@intel.com>
If there is more than one VLAN defined when any reset that affects the
PF is initiated, after the reset rebuild, no traffic will pass on any
VLAN but the last one created.
This is caused by the iteration though the VLANs during replay each
clearing the vsi_map bitmap of the VSI that is being replayed. The
problem is that during the replay, the pointer to the vsi_map bitmap is
used by each successive vlan to determine if it should be replayed on
this VSI.
The logic was that the replay of the VLAN would replace the bit in the
map before the next VLAN would iterate through. But, since the replay
copies the old bitmap pointer to filt_replay_rules and creates a new one
for the recreated VLANS, it does not do this, and leaves the old bitmap
broken to be used to replay the remaining VLANs.
Since the old bitmap will be cleaned up in post replay cleanup, there is
no need to alter it and break following VLAN replay, so don't clear the
bit.
