From: Somnath Kotur <somnath.kotur@broadcom.com>

HWRM_RING_FREE followed by a HWRM_RING_ALLOC is not guaranteed to
have the same FW ring ID as before.  So we must reinitialize the
RSS table with the correct ring IDs.  Otherwise, traffic may not
resume properly if the restarted ring ID is stale.  Since this
feature is only supported on P5_PLUS chips, we call
bnxt_vnic_set_rss_p5() to update the HW RSS table.
