Hello,
The eepro100.c driver has a subtle change
from RH7.1 source to RH7.2 source. Because
of this, the ioctl SIOCGIFMAP (which reads from
the dev structure dev->ioaddr) returns the
"ioremap"ped value of the phys addr (pci_config_space)
The first line of the code was...
#define USE_IO 1
which is deleted in RH7.2 code.
Can anyone, please, explain the following questions that I have?
a. What does that line really mean?
I mean why would one want to do something like define to 1
and then use
#ifdef USE_IO .... #else.... #endif
Does it serve any purpose?
b. Why was this line deleted in the 7.2 release?
Was it a mistake? Or was it on purpose? I would
think it was the latter. :-)
c. Are there change logs available for this or
any open source files, which would tell me/us
why A particular change is made to A file??
d. Is there other way to get the base address from
the driver (not the ioremapped address, but the actual
base address, as seen in /proc/pci or /proc/ioports)
Thanks for all your help in advance.
Please reply (CC:) to me as I am NOT subscribed
