Add support for a new type of input_xfrm: Symmetric OR-XOR.
Symmetric OR-XOR performs hash as follows:
(SRC_IP | DST_IP, SRC_IP ^ DST_IP, SRC_PORT | DST_PORT, SRC_PORT ^ DST_PORT)

Configuration is done through ethtool -x/X command.
Also performed some misc cleanups for things I've noticed while touching
the area, see individual patches for information.

Kernel submission was merged:
https://lore.kernel.org/netdev/20250224174416.499070-1-gal@nvidia.com/

Thanks,
Gal
