drivers/net: delete all code/drivers depending on CONFIG_MCA
The support for CONFIG_MCA is being removed, since the 20 year old hardware simply isn't capable of meeting today's software demands on CPU and memory resources. This commit removes any MCA specific net drivers, and removes any MCA specific probe/support code from drivers that were doing a dual ISA/MCA role. Cc: "David S. Miller" <davem@davemloft.net> Cc: James Bottomley <James.Bottomley@HansenPartnership.com> Cc: netdev@vger.kernel.org Signed-off-by: Paul Gortmaker <paul.gortmaker@windriver.com>

The 3c523 responds with adapter code 0x6042 at slot

0: card enable
|

2,1: csr address select
|

00 = 0300

10 = 2300

5: set to disable on-board thinnet

7,6: (read-only) shows selected irq

01 = 7
|

10 = 3

11 = 9

The interrupt-select register is at xxx3 and uses one bit per irq.

2: int 3

Again, the documentation stresses that the setup register

should never be written. The interrupt-select register may be

written with the value corresponding to bits 7.6 in
|

the setup register to insure corret setup.
