Subject: net/avf: fix Rx interrupt mapping
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=efe73c0d1d2bcfc17f726245bd880acdc06f9718;p=dpdk.git

net/avf: fix Rx interrupt mapping

Vector used for rx mapping is different if WB_ON_ITR
is supported. The mapping table need to be updated.

Fixes: d6bde6b5eae9 ("net/avf: enable Rx interrupt")
