epic100: Test __BIG_ENDIAN instead of (non-existent) CONFIG_BIG_ENDIAN
Probably no one has used this driver on big-endian systems, since it was setting up descriptor swapping if CONFIG_BIG_ENDIAN is set, which it never is, since that symbol is not mentioned anywhere else in the kernel source. Switch this test to a check for __BIG_ENDIAN so it has a chance at working. Signed-off-by: Roland Dreier <rolandd@cisco.com> Acked-by: Jeff Garzik <jgarzik@redhat.com> Signed-off-by: David S. Miller <davem@davemloft.net>
