From: Beilei Xing Date: Tue, 6 Feb 2018 05:33:31 +0000 (+0800) Subject: net/i40e: fix Rx interrupt X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=378cc7f569a678e1c8469094104b757864c4ad05;p=dpdk.git net/i40e: fix Rx interrupt This patch fixes interval error and corrects macros when enabling Rx interrupt mode. The patch also fixes a logical error during supporting multiple drivers.
