Subject: [net] e1000e: update to latest upstream
Message-id: 20071219154538.GN28834@gospo.usersys.redhat.com
O-Subject: [RHEL5.2 PATCH] e1000e: update to latest upstream
Bugzilla: 252003
This is an update to the latest e1000e driver upstream. It pulls all
the needed changes from Linus's tree as well as any needed ones from
Jeff's netdev-2.6 tree.
What's significant about this patch related to RHEL5 is that it includes
the following upstream commit that applies to e1000e (not e1000 or igb):
commit b3637100199b2679cd2f39d47a0061a3398cd3ca

e1000/e1000e: Move PCI-Express device IDs over to e1000e
e1000e will from now on support the PCI-Express adapters that
previously were supported by e1000. This support means better
performance and easier debugging from now on for both the old
PCI-X/PCI hardware and PCI-Express adapters.
This patch also moves 3 recently merged device IDs over to e1000e
that are identical to quad-port versions of already existing
dual port versions. With this last bit every former e1000 pci-e
device should work now with e1000e.
Here is a brief list of which gigabit driver to use with which
adapter:
e1000:
82540 -> 82547
e1000e:
82571 -> 82573
ich8, ich9 (82562 or 82566)
es2lan (80003eslan)
igb: (not yet merged, only available from e1000.sf.net)
82575
Signed-off-by: Auke Kok <auke-jan.h.kok@intel.com>
Signed-off-by: Jeff Garzik <jeff@garzik.org>
I would like to drop support for these adapters from e1000 (I'd settle
for dual-support for an update or two), but either way I would like them
included in e1000e.
This will resolve BZ 252003.
