This is the relevant portion from ax88772_bind():
if (((ret = asix_read_cmd(dev, AX_CMD_READ_MII_REG,
0x0010, 2, 2, buf)) < 0)
|| (*((u16 *)buf) != 0x003b)) {
dbg("Read PHY register 2 must be 0x3b00: %d", ret);
goto out2;
}
Looks like I need to change that to a asix_mdio_read_le() call. Try the
attached patch with the caveat that I haven't tested it yet, I'm on a
plane. It should be right though I might need to swap the != 0x3b00 to
0x003b. If you could try it against PPC and x86, that'd be great. I
only have access to x86 myself.
