mxser: drop ISA support
While mxser PCI cards are still around and produced (Moxa provided me with two recently), ISA cards are obsolete for a long time. I haven't seen anyone using the cards and the ISA code paths are barely tested. Hence, remove ISA support from mxser driver so that we can clean the driver up.

This driver will activate ISA boards according to the parameter set

in the driver. After all specified ISA board activated, PCI board

will be installed in the system automatically driven.

Therefore the board number is sorted by the CAP address of ISA boards.

For PCI boards, their sequence will be after ISA boards and C168H/PCI

has higher priority than C104H/PCI boards.

|

------------------------------------------
|

|
||||
For PCI boards user, please skip this step.
|
||||
|
||||
In module mode, the CAP address for ISA board is given by
|

parameter. In static driver configuration, you'll have to
|
||||
assign it within driver's source code. If you will not
|
||||
install any ISA boards, you may skip to next portion.
|
||||
The instructions to modify driver source code are as
|
||||
below.
|
||||
|
||||
a. run::
|
||||
|
||||
# cd /moxa/mxser/driver
|
||||
# vi mxser.c
|

|

b. Find the array mxserBoardCAP[] as below::
|
||||
|
||||
static int mxserBoardCAP[] = {0x00, 0x00, 0x00, 0x00};
|
||||
|
||||
c. Change the address within this array using vi. For
|
||||
example, to driver 2 ISA boards with CAP address
|
||||
0x280 and 0x180 as 1st and 2nd board. Just to change
