Hi Alan,

The following patch is a preliminary attempt for cleaning network drivers in
2.4 (drivers for 3Com boards for beginning). It contains:

- cleaning version printing as Jeff suggests (modular - always, built in -
if detected)
- added MODULE_PARM_DESC (the main reason I've created the patch)
- made version __initdata
- a comment fix (3c501)
- added KERN_* markers to some printk's (only a few)
- enabled modular isapnp usage by 3c509

BTW, Looking at the "options" parameter in some drivers I found that using
it might be ugly in some cases and do not allow specyfic settings. For
example it is difficult to set 10Mbps/half-duplex not changing media type in
some drivers as it requires "options=0" setting, which is simply ignored.
Parameters like duplex setting should be IMO three-state (full/half/not
changed) while there's only one bit in "options" assigned to them currently.
Jeff, Alan, what do you think of changing the method for media/link type
setting and unifying it across drivers ?
Of course, I think of it as a 2.5 project...

Andrzej
