Subject: lspci: Use mangled vendor/device ID when examining vendor caps
X-Git-Tag: v3.11.0~95
X-Git-Url: http://mj.ucw.cz/gitweb/?a=commitdiff_plain;h=adf7de0ec6a1b734c00667879d36c1198670958a;p=pciutils.git

lspci: Use mangled vendor/device ID when examining vendor caps

Given that PCI VFs are expected to have a vendor and device ID of
0xffff, when examining vendor capabilities use the mangled vendor and
device IDs (typically copied from the PF) rather than those read from
the VF configuration space.
