Subject: [dpdk-dev] [PATCH] vhost: Fix the vhost broken issue
Date: Mon, 13 Oct 2014 15:39:40 +0800
Message-ID: <1413185980-17348-1-git-send-email-changchun.ouyang@intel.com> (raw)

As the vhost sample is broken by the following commit,  
  commit 08b563ffb19d8baf59dd84200f25bc85031d18a7    
  Author: Olivier Matz <olivier.matz@6wind.com>

  mbuf: replace data pointer by an offset

It leads to segment fault error in vhost when binding a virtio
device MAC address to its corresponding VMDq pool by executing
command line 'start tx-first' in test-pmd on guest.

This patch fixes that issue.
