[dpdk-stable] [PATCH 13/17] net/bnxt: fix vnic RSS configure function

Tue Dec 8 21:11:30 CET 2020


From: Kalesh AP <kalesh-anakkur.purayil at broadcom.com>

1. moved invalid VNIC id check to the beginning of the function.
2. removed a duplicate check which avoids unnecessary code indentation.

Fixes: 49d0709b257fc ("net/bnxt: delete and flush L2 filters cleanly")
