I've made some changes based on advice from Willy Tarreau. The changes don't influence the IPv6 performance numbers on our board relative to the previous patch. I still get about 90% of IPv4 performance. Enabling NETIF_F_TSO6 still causes problems; that will probably have to be addressed in a sepa

[PATCH] improve mvneta (Marvell 370) driver TCPv6 performance

2015-06-26 Thread Phil Hofer
TCP performance over IPv6 was only about 60% of IPv4 performance. This patch makes up most (but not all) of the difference. Signed off by: Thomas Petazzoni (thomas.petazz...@free-electrons.com) diff --git a/drivers/net/ethernet/marvell/mvneta.c b/drivers/net/ethernet/marvell/mvneta.c index 5bdf78
