evaluate: bail out with concatenations and singleton values
The rule:
# nft add rule x y iifname . oifname p . q
is equivalent to:
# nft add rule x y iifname p oifname q
Bail out with:
Error: Use concatenations with sets and maps, not singleton values
add rule x y iifname . oifname p . q
^^^^^^^^^^^^^^^^^ ~~~~~
instead of:
BUG: invalid expression type concat
nft: evaluate.c:1916: expr_evaluate_relational: Assertion `0' failed.
Aborted
