Subject: [dpdk-dev] [PATCH v4 10/13] ixgbevf: cleanup unnecessary interrupt handler
Date: Wed,  4 Nov 2015 16:45:37 +0800	[thread overview]
Message-ID: <1446626740-28824-11-git-send-email-cunming.liang@intel.com> (raw)
In-Reply-To: <1446626740-28824-1-git-send-email-cunming.liang@intel.com>

As ixgbe vf doesn't support lsc, the patch removes those unused code.
In addition, it does some tiny cleanup.
