Subject: [PATCH] 2.4/2.5: ewrk3 ethtool support
Date: Fri, 18 Oct 2002 22:01:29 -0400 [thread overview]
Message-ID: <20021019020128.GA21496@www.kroptech.com> (raw)
The following patch adds support for ethtool to the ewrk3 driver. It is against
2.5-BK but should apply to any recent 2.5 and 2.4 as well. In addition to adding
ethtool support, it also removes the cli/sti fixup attribution from the
changelog since that didn't actually go in yet and fixes a small style issue I
introduced in the multi-card support patch.
Note that for 2.5 ewrk3 still needs VDA's cli/sti removal patch, which I will
send along in a separate mail along with some other cleanups.
This has been tested on an SMP x86 box containing 3 DE205 NICs.
