consolidate sockopts into :file:`setsockopt.c`
add support for ipv[4|6] pseudoheader checksum to :file:`checksum.c`

A list of some interesting edge cases in YANG and the FRR Northbound API.

leafrefs as list keys

A leafref is a reference to a leaf in another part of the data tree. Being leaves themselves, they can be used as the key for a list:

list mylist {

Wherever possible, disable loading the CLI tree for massive performance gains (> 3x)
If running in parallel, disable pidfile checks
Skip option parsing
Disable checksums where applicable

Challenges with running CPU pinned processes within Docker

Programs that want to bind themselves to free cores present some challenges
when run within Docker.

CPU pinning allows a program to request it be assigned exclusively to a core or set of cores This improves cache locality and other factors that become relevant for extremely CPU bound processes, especially in combination with other configurations that prevent the scheduler from assigning other processes

	- In Windows, open Settings -> Bluetooth & other devices
	- If Teric has been paired before, click it and click "Remove device"
	- Open Subsurface, go to Import -> From Dive Computer
	- In Windows Settings, click Add Bluetooth or other device -> Bluetooth
	- On Teric, initiate Bluetooth mode (it seems it only sends one beacon at
	startup, so Windows must be listening on the adapter first)
	- Pair the Teric when it appears in the Windows panel
	- Go to Subsurface, select the Teric as the model, and click "Download"
	- If it fails, repeat all steps; sometimes it only works on the second try

	- hello
