-Subject: [PATCH 24/25] net/enic: fix Rx scatter with multiple queues
-
-The Rx scatter patch failed to make a few changes and resulted in
-problems when using multiple receive queues (RQs) in DPDK (ie RSS)
-since the wrong adapter resources were being used.
-
-- get and use the correct completion queue index associated with a
- receive queue.
-- set the correct receive queue index when using RSS
-
-Fixes: 856d7ba7ed22 ("net/enic: support scattered Rx")
