Subject: Re: [dpdk-dev] [Pktgen] [PATCH] pktgen_setup_packets: fix race for packet header
Date: Fri, 2 Oct 2015 11:25:11 +0000	[thread overview]
Message-ID: <D23427A1.536D%keith.wiles@intel.com> (raw)
In-Reply-To: <560E4D2E.7080207@samsung.com>

I looked at the code and everything looks good. I will try to merge the
code next week as I am traveling again :-(

Thanks for the patch, I am glad you found this problem as I believe
someone else reported something odd in that area, but was not able to give
me many details.
