fix endian lossage in forcedeth
a) if you initialize something with le32_to_cpu(...), then |= it with host-endian and feed to cpu_to_le32(), it's most definitely *not* __le32. As sparse would've told you... b) the whole sequence is |= cpu_to_le32(host-endian constant) Signed-off-by: Al Viro <viro@zeniv.linux.org.uk> Signed-off-by: Jeff Garzik <jeff@garzik.org>
