Applied, thanks Elise.
BTW, we have to fix "nft describe", look:
# nft describe tcp dport
payload expression, datatype inet_service (internet network service) (basetype
integer), 16 bits
pre-defined symbolic constants:
tcpmux 0x0100
echo 0x0700
...
The user relies on nft describe to know what datatype and possible
values are possible for a given selector. In this case, they are
expressed in network byte order.
The problems seems to be in expr_describe(), the expression already
provides the byteorder, so I guess symbol_table_print() needs to get
this byteorder as parameter to swap bytes when required.
This is a fix, so I would appreciate if you focus on this, thanks!
