Message-Id: <1319745221-30880-6-git-send-email-nhorman@tuxdriver.com> Date: Thu, 27 Oct 2011 15:53:41 -0400 From: Neil Horman <nhorman@...driver.com> To: netdev@...r.kernel.org Cc: root <root@...-dinar-01.lab.bos.redhat.com>, Neil Horman <nhorman@...driver.com>, "David S. Miller" <davem@...emloft.net> Subject: [RFC PATCH 5/5] net: add FCLONE_SCRATCH use to ipv6 udp path From: root <root@...-dinar-01.lab.bos.redhat.com> Like the ipv4 path, the ipv6 path can benefit from this change by taking advantage of the unused space at the tail of an skbuffs data area. Mark ipv6 udp multicast frames as being elligible for scratch fcloning. Signed-off-by: Neil Horman <nhorman@...driver.com> CC: "David S.
