A few people have reported that 3c509.c is incorrectly selecting
the BNC connector when used non-modularly.
This is due to 2.2-vs-2.4 incompatibility in the handling
of the `ether=' kernel option. The `ether=' option takes
up to five args. If any are omitted, they default to zero
in kernel 2.2 and to -1 in kernel 2.4. This will break
a lot more drivers than just 3c509 - five or six, including
natsemi.c and hamachi.c.
This patch restores the 2.2 behaviour.
Notes:
- The `netdev=' and `ether=' kernel options are identical.
So `ether_setup()' is removed, and the `ether=' option
calls netdev_boot_setup() instead. We can re-fork the
implementation later if these options become different.
- drivers/net/net_init.c:ether_config() isn't used
anywhere. It has been removed.
- In 3c59x.c and starfire.c: remove the recently-added
workarounds for dev->mem_start == -1.
Patch is against 2.4.2-ac4. It also applies to 2.4.2 (ignore
the rejects).
