virtio-net: fix cross-endianness support
virtio-net used to work on cross-endianness configurations, but doesn't anymore with recent guest kernels, as the new features don't handle endianness correctly. This patch fixes wrong conversion, and add missing ones to make virtio-net working. Tested on the following configurations: - i386 guest on x86_64 host - ppc guest on x86_64 host - i386 guest on mips host - ppc guest on mips host Cc: Anthony Liguori <aliguori@us.ibm.com> Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>
