netlink_delinearize: support for bitfield payload statement with binary operation
Add a new function to deal with payload statement delinearization with
binop expression.
Infer the payload offset from the mask, then walk the template list to
determine if estimated offset falls within a matching header field. If
so, then validate that this is not a raw expression but an actual
bitfield matching. Finally, trim the payload expression length
accordingly and adjust the payload offset.
instead of:
@nh,8,5 set 0x0
it displays:
ip dscp and 0x1
Update tests/py to cover for this enhancement.
