[dpdk-dev] [PATCH 05/11] net/bnxt: fix RSS reta indirection table update

[Ajit Khaparde <ajit.khaparde@broadcom.com>]

We are trying to update the indirection table for all the VNICs.
We should update the table only for the default vnic0.
This patch fixes the above issue.

Fixes: d819382543f3 ("net/bnxt: add RSS redirection table operations")
