So far if invalid priority name was specified the error message referred
to the whole chain/flowtable specification:
nft> add chain ip x h { type filter hook prerouting priority first; }
Error: 'first' is invalid priority in this context.
add chain ip x h { type filter hook prerouting priority first; }
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
With this patch this reference is made specific to the priority
specification:
nft> add chain ip x h { type filter hook prerouting priority first; }
Error: 'first' is invalid priority in this context.
add chain ip x h { type filter hook prerouting priority first; }
^^^^^^^^^^^^^^
`prio_spec` is also reused to keep naming intuitive. The parser section
formerly named `prio_spec` is renamed to `int_num` as it basically provides the
mathematical set of integer numbers.
