New feature: PCIe pass-through support

[AlbrechtL]

In commit 2bb5a11 I added PCIe pass-through support

Usage see docker-compose.yml

openwrt-docker/docker-compose.yml

Lines 50 to 58 in 07f4eea

	# PCI and PCIe pass-through
	# Host system requirements
	# - IOMMU CPU virtualization feature (e.g. Intel VT-d) has to enabled in bios
	# - Host kernel has to switch on intel_iommu=on or amd_iommu=on
	# - Host kernel module 'vfio-pci' has to exists
	# - Ubuntu 24.04 is working by default
	# Format <bus:device.function> like 'lspci' is given
	# If unset -> disabled
	#PCI_1: "00:1f.6"

This feature came out from this discussion: #15

Is multiple support enabled?
If i add another PCI_2 I only ever see PCI 1 get attached.

I have a few boards with multiple Wi-FI NICs that will have different functions - one as an AP / and one for wireless mesh.

[AlbrechtL]

Understood. So to pass-through two PCIe devices would be sufficient?

I added support for PCI_2 in 4571b04.

I added support for PCI_2 in 4571b04.

I cloned the new repo, and it still only seems to pass in whatever I label as PCI_1:

Mh, maybe the build pipeline wasn't finished at that time. Now the OpenWrt 24.10.1 version is finished. Did you pull the newest image albrechtloh/openwrt-docker:latest from docker hub?

Please set both PCI_1 and PCI_2.
