Subject: ionic: keep filters across FLR
Patch-mainline: v6.8-rc1
Git-commit: 45b84188a0a4b91c9763105381486916cc4b861f
References: jsc#PED-6953

Make sure we keep and replay the filters and RSS config across
an FLR by using our FW_RESET flag.  This gets checked on the
way down and on the way back up to help determine how much LIF
state to keep and restore across a reset action.
