Michael Braun says: This results for nft list ruleset in nft: netlink_delinearize.c:1945: binop_adjust_one: Assertion `value->len >= binop->right->len' failed. This is due to binop_adjust_one setting value->len to left->len, which is shorther than right->len. Additionally, it does not seem correct to alter set elements from parsing a rule, so remove that part all together.
