Lazy find Linux interface from PCI ID GitHub

It is sometimes hard to find which PCI ID corresponds to which NIC in Linux.

This script shows the mapping between PCI IDs and NICs.

Tested On Ubuntu 18.04.


grep PCI_SLOT_NAME /sys/class/net/*/device/uevent

# will show something like
# /sys/class/net/rename5/device/uevent:PCI_SLOT_NAME=0001:00:02.0
# /sys/class/net/rename6/device/uevent:PCI_SLOT_NAME=0002:00:02.0
# /sys/class/net/rename7/device/uevent:PCI_SLOT_NAME=0003:00:02.0

That's all, folks!
