Defined in:
nl-linux/generated/nl/linux/nftables.rb

Overview

The bitwise expression supports boolean and shift operations. It implements the boolean operations by performing the following

operation
dreg = (sreg & mask) ^ xor

with these mask and xor values:

op      mask    xor
----    ----    ---
NOT:     1       1
OR:     ~x       x
XOR:     1       x
AND:     x       0
