Subject: [RFC 7/8] mbuf: move sequence number in second cache line
Date: Tue, 24 Jan 2017 16:19:32 +0100	[thread overview]
Message-ID: <1485271173-13408-8-git-send-email-olivier.matz@6wind.com> (raw)
In-Reply-To: <1485271173-13408-1-git-send-email-olivier.matz@6wind.com>

Move this field in the second cache line, since no driver use it
in Rx path. The freed space will be used by a timestamp in next
commit.
