What this PR does / why we need it
Fixes Antrea dual-stack deployment failure on Ubuntu 22.04 caused by
ip6tables-nftnot supporting the--or-markoption.Which issue(s) this PR fixes
Fixes #7602
How I did it
Replaced
--or-markwith--set-xmark value/valuein iptables mangle rules for marking LOCAL output packets.According to the iptables man page,
--or-mark bitsis a "mnemonic for--set-xmark bits/bits" - they are semantically equivalent, but--set-xmarkhas wider compatibility across different iptables implementations (legacy and nft backends).
