From e22856313fff2db12d8e132dad446bbf74cf29a5 Mon Sep 17 00:00:00 2001 From: Ferruh Yigit Date: Thu, 4 Aug 2016 16:54:05 +0100 Subject: [PATCH] kni: remove memzone lookup to get mbuf address Originally mempool->mz is used to get address of the mbuf, but now address get directly from mempool, so mempool->mz information is not required.
