Kicinski: netdev in 2024

Description:
Kernel networking maintainer Jakub Kicinski reviews progress in
the networking subsystem in 2024. Work on relieving the rtnl_lock pressure 
has continued throughout
	the year. The rtnl_lock is often mentioned as one of the biggest
	global locks in the kernel, as it protects all of the network
	configuration and state. The efforts can be divided into two broad
	categories  converting read operations to rely on RCU protection
	or other fine grained locking (v6.9, v6.10), and splitting the lock
	into per-network namespace locks (preparations for which started in
	v6.13).
