From: Mark Rustad Date: Mon, 13 Jul 2015 18:40:07 +0000 (-0700) Subject: PCI: Add VPD function 0 quirk for Intel Ethernet devices X-Git-Tag: v4.1.8~64 X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=884372a6b09964f236fa8148bc831c84f68d8a09;p=users%2Fjedix%2Flinux-maple.git PCI: Add VPD function 0 quirk for Intel Ethernet devices commit 7aa6ca4d39edf01f997b9e02cf6d2fdeb224f351 upstream. Set the PCI_DEV_FLAGS_VPD_REF_F0 flag on all Intel Ethernet device functions other than function 0, so that on multi-function devices, we will always read VPD from function 0 instead of from the other functions.
