From 7365bcfa32d2c9d212c41d52ff3509d70b6a3466 Mon Sep 17 00:00:00 2001 From: Paul Durrant Date: Wed, 16 Oct 2013 17:50:30 +0100 Subject: [PATCH] xen-netback: Unconditionally set NETIF_F_RXCSUM There is no mechanism to insist that a guest always generates a packet with good checksum (at least for IPv4) so we must handle checksum offloading from the guest and hence should set NETIF_F_RXCSUM.
