[dpdk-dev] [PATCH] kni: memzone info not required to get mbuf address

2016-08-04 Thread Ferruh Yigit
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.

Fixes: d1d914ebbc25 ("mempool: allocate in several memory chunks by default")
