Comment 2 John W. Linville 2005-03-21 20:43:01 UTC
I have incorporated the patch in the test kernels available here:

   http://people.redhat.com/linville/kernels/rhel3/

Please give them a try and report the results.  Thanks!

P.S.  What purpose is served by sending a large udp-packet without a checksum? 
Just curious... :-)

Comment 3 Hosting 2000 Account 2005-03-22 09:03:52 UTC
I could not find the sk98lin driver in the kernel package. Isn't it part of
kernel-unsupported?

Novell Border Manager for Windows obviously sends udp packets without checksum,
which our router with sk98lin drops. 

Comment 4 John W. Linville 2005-03-22 15:58:14 UTC
Right you are...I have included the unsupported rpms as well...they are
available at the same link as in comment 2.

Please give them a try and report the results.  Thanks!

It works great. Thank you.

A fix for this problem has just been committed to the RHEL3 U6
patch pool this evening (in kernel version 2.4.21-32.1.EL).
