Deprecated

The method described in this gist has been deprecated/superceeded by kiler129/early-vfio-pci-isolate tool.
It is more robust, configurable, and doesn't hack around scripts that are sometimes overwritten by system updates. The tool uses similar methods to the ones described below, but extends the capabilities by e.g. easy NVMe passthrough by S/N.

The description below has been preserved for historical context. At the time of writing, the tool above has been tested for ~6 months across multiple systems.

	0. Don't have a SIM card in when you're updating radio firmware or it will bomb out partway through as it changes from internal IP to IP passthrough

	1. Disable external IP passthrough mode: Network Setting -> Broadband -> Cellular APN -> #1 -> Modify icon -> "IP Passthrough" slider to off

	2. Use "management" Wi-Fi AP as general Wi-Fi AP (with limitations) -> Network Setting -> Bridge1 -> Modify icon -> Move the Wi-Fi AP interface to the pane on the right alongside LAN1
	NOTE: by default, once you do the above, the router will happily pass traffic from devices on the Wi-Fi AP to other devices on the LAN1 subnet, but will block traffic originating from the Wi-Fi AP from exiting to the Internet via the LTE side of the device. You can clumsily hack around this by setting another device, e.g. another Wi-Fi AP or Raspberry Pi or Cray supercomputer, as the default gateway for the LAN1 subnet in your DHCP server config, and pointing that device at the Zyxel as its default GW. This adds additional hops, but enabl

	errno.h - C Error Codes in Linux
	All the Linux/C error codes are listed below.

	I occasionally google C error codes, but always end up grepping through /usr/include to find the answer.

	UPDATE : 07July2025
	There's a utility named `errno`, part of the `moreutils` package; once installed, you can simply run
	`errno -l`
	to see all possible errno's and their English error message!
