Subject: net/iavf: fix RSS initialization
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=91fba40ea9b9c3f0ff7f583fbe5627188a49b24e;p=dpdk.git

net/iavf: fix RSS initialization

When the default RSS is disabled during initialization, the RSS should
be turned on when creating RSS rule.

This patch adds support to configure RSS key and lookup table even
when the default RSS is disabled.

Fixes: c678299594a8 ("net/iavf: fix default RSS configuration")
