Subject: [PATCH] Use PCI_SLOT_NAME cut instead of ls -ld cut more precisely

If the vf port file like /sys/class/net/ens4f0/device/virtfn0 date is
'Jan 5', ls -ld result will be 'Jan  5', there are two space between
Jan and 5, if use the old "cut -f 11 -d ''", it will not get the vf pci
id, should be cut 12. So here we use the context in
/sys/class/net/p2p1/device/virtfn*/uevent, do with it will be more
precise.
