[epic] Re: epic100.c fix for 2.2.x kernels

[Andreas Steinmetz]

Ok,
got that, I was missing pci-scan.c - I was already guessing by source reading
with the required headers and missed this source completely (lack of at least
hints on the driver's web page). Nevertheless the problem in the source remains
(I just did a quick source code read of the affected routines), so the fix I
posted is still required.
Now, what I don't like is that except for a (temporary) test machine that will
become a future server all of my servers run with module support disabled  -
first the hardware doesn't change and second there's security reasons. So using
this new version of the driver I'll have either to modify the kernel's network
driver build or (single source version) include pci-scan.c in epic100.c (brrr,
dirty). Sigh.
