SubjectRe: bug in /net/core/dev.c



Hi Keith,
This is a cure the syntom not the problem, build order shouldn't mess up
something this simple.
I've forwarded your patch to Ulrich & Martin ( the s390 maintainers ) &
they may use it
seeing as you & possibly others would prefer a /drivers/net/s390.
David admitted it is a bug, if the patch is good hopefully it will be
taken,
it if better can be done hopefully someone will do better.

Leave s390 separate for the moment, all the other architectures work
the same way.

Minimal (and totally untested) patch to compile s390/net as part of the
other network drivers follows - if it's good enough for acorn, it's
good enough for s390. The method is as ugly as hell but it is the
least possible change for 2.4, major redesign will have to wait for
2.5. Patch against 2.4.6-pre2.
