tun: Optimise handling of bogus gso->hdr_len
As all current versions of virtio_net generate a value for the header length that's too small, we should optimise this so that we don't copy it twice. This can be done by ensuring that it is at least as large as the place where we'll write the checksum. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: David S.
