[CFT][PATCH] net/8390: apne.c - read out and log PCMCIA cftable entries

[Michael Schmitz <schmitzmic@gmail.com>]

Could someone with a 'normal' Amiga PCMCIA ethernet card (supported
by the current apne driver) please test this patch and send me the
kernel log output relating to the apne driver probe? 

At least for the 16 bit card that Alex tested, the PCMCIA config
tuple data correctly records the 16 bit IO width of the card. I
need to know whether 8 bit cards also report 16 bit IO width, or
only 8 bit.

The IO width from the config table data, iff accurate, would allow
auto-probing of 16 bit cards. That would make it easier to get
a patch to support 16 bit cards accepted.

Thanks,

	Michael


Read the card's CISTPL_CFTABLE_ENTRY tuple, and log to the
kernel log buffer. This tuple ought to hold information
about the IO width of the card memory window that can be used
in autoprobing to detect 16 bit datapath cards.
