Subject: MSI-X not enabled for ixgbe device-passthrough
Date: Wed, 24 Mar 2010 16:54:15 +0100 [thread overview]
Message-ID: <4BAA35A7.2090104@suse.de> (raw)
Hi all,
I'm trying to setup a system with device-passthrough for
an ixgbe NIC.
The device itself seems to work, but it isn't using MSI-X.
So some more advanced features like DCB offloading etc
won't work.
lspci output of the device:
