That is because there are several cases where one PCI-ID implements multiple functions served by different drivers. So far there is no really clean solution to this problem and for e1000 with PCI-E IDs it would do the wrong thing. -Andi From mboxrd@z Thu Jan 1 00:00:00 1970 From: Andi Kleen Subject: Re: [ANNOUNCE] e1000 to e1000e migration of PCI Express devices Date: Tue, 08 Apr 2008 16:56:52 +0200 Message-ID: <87iqyspf7v.fsf@basil.nowhere.org> References: <47F69965.7030303@intel.com> <20080408083606.GA20863@elte.hu> Mime-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit Cc: "Kok, Auke" , Andrew Morton , Jeff Garzik , e1000-list , NetDev , "Allan, Bruce W" , Linux Kernel Mailing List , Jesse Brandeburg , "Rafael J.
