[PATCH] 3c59x: fix networking for 10base2 NICs 



The "3c59x: use mii_check_media" patch introduced a netif_carrier_off in
vortex_up.  10base2 stoped working because of this.  This is removed.

Tx/Rx reset is back in vortex_up because the 3c900B-Combo stops working after
changing from half duplex to full duplex when Tx/Rx reset is done with
vortex_timer.

Also brought back some mii stuff to be sure that it does not break something
else.

Thanks to Pete Clements <clem@clem.clem-digital.net> for reporting and testing.
