Subject: net/iavf: fix initialization with quanta configuration
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=1c735a52b38aee8fe27090223215151dc20c23a5;p=dpdk.git

net/iavf: fix initialization with quanta configuration

When kernel driver does not support quanta size configuration,
it will return error. We do not expect it to occur in default
initialization process.

Fixes: b14e8a57b9fe ("net/iavf: support quanta size configuration")
