Packets destined to the to-be-stopped queue should not be dropped
(neither in HW nor in the driver), so re-program the RSS Table without
this queue on stop and add it back to the table on start unless it
is a Representor VF.
Since 0th entry is used for default ring, use fw_grp_id + 1 to change
the RSS table population logic by programming valid IDs instead of the
default zeroth entry in case of an invalid fw_grp_id.
Destroy and recreate the trio of Rx rings(compl, Rx, AG) every time in
start so that HW is in sync with software.
Fixes: 9b63c6fd70 ("net/bnxt: support Rx/Tx queue start/stop")
