Subject: Re: [RHEL5.1 PATCH] ixgb: update to driver version 1.0.126-k2 (bz223380)
Date: Wed, 20 Jun 2007 09:57:53 -0700
Bugzilla: 223380
Message-Id: <46795C91.8090308@redhat.com>
Changelog: [net] ixgb: update to driver version 1.0.126-k2
This patch updates the ixgb Intel 10GbE driver to version 1.0.126-k2 (as
found upstream in 2.6.22-rc4). The driver has undergone touch testing
and is currently going through more intensive testing in Intel LAD
Validation labs. The patch was generated against 2.6.18-21.el5.
Thanks,
