That should be fixed with this one:

commit f1ecfd5d3b69d98b814435758c485e6fd0e112de
Author: Ursula Braun <braunu@de.ibm.com>
Date:   Mon Oct 22 16:16:14 2007 +0200

    remove header_ops bug in qeth driver
   =20
    Remove qeth bug caused by commit:
    [NET]: Move hardware header operations out of netdevice.
   =20
    This is the second part of the qeth header_ops patch, since
    first patch sent 10/19 has been insufficient.
    Nevertheless first patch is still valid and should be kept.
