Subject: [dpdk-dev] [PATCH] net/iavf: fix multi-queue Rx interrupt for VF
Date: Thu, 5 Sep 2019 03:22:40 +0000 [thread overview]
Message-ID: <20190905032240.23239-1-lunyuanx.cui@intel.com> (raw)
The original issue was that the last queue could not
be mapped to the interrupt vector, so the last queue
could not receive the package in the interrupt mode.
This patch fix the issue.
Fixes: d6bde6b5ea ("net/avf: enable Rx interrupt")
