There is a problem with ranges and comparisons. Here some examples of this bug.

With ttl:
$ sudo nft add rule ip test input ip ttl 13-15 counter drop 
BUG: invalid byte order conversion 0 => 2
nft: src/evaluate.c:153: byteorder_conversion_op: Assertion `0' failed.

nft add rule ip test input ip ttl lt 9 counter drop
BUG: invalid byte order conversion 0 => 2
nft: src/evaluate.c:153: byteorder_conversion_op: Assertion `0' failed.

 $ sudo nft add rule ip test input ip ttl gt 9 counter drop
BUG: invalid byte order conversion 0 => 2
nft: src/evaluate.c:153: byteorder_conversion_op: Assertion `0' failed.

With ah in ipv4
$ sudo nft add rule ip test input ah spi 500-550 counter drop
BUG: invalid byte order conversion 0 => 2
nft: src/evaluate.c:153: byteorder_conversion_op: Assertion `0' failed.

With ah in IPv6
* spi (ipv6)
$ sudo nft add rule ip6 test6 input ah spi 500-550 counter drop 
BUG: invalid byte order conversion 0 => 2
nft: src/evaluate.c:153: byteorder_conversion_op: Assertion `0' failed.

With esp in spi:
 $ sudo nft add rule ip test input esp spi 500-550 counter drop
BUG: invalid byte order conversion 0 => 2
nft: src/evaluate.c:153: byteorder_conversion_op: Assertion `0' failed.


I can always reproduce this bug in these cases.
