i'm afraid this is wrong. the register step (which asix_eth_get_info is
afaict) should not touch the hardware (other than to extract the MAC address).
the init func is supposed to bring up the hardware from scratch since the
expectation is that the halt func brings it down completely. if it's not
really possible to completely "bring down" the hardware, then have the
asix_init func declare a local static int so that it does the "full" bring up
only once.
so NAK this patch as is
