Yes, I think we should extend bitwise first, since that would make this
work:
src/nft -e -a --debug=netlink add rule inet filter input \
ct mark set "ct mark & 0xffff0000 | meta mark & 0xffff"
inet filter input
[ meta load mark => reg 2 ]
[ bitwise reg 2 = (reg=2 & 0x0000ffff ) ^ 0x00000000 ]
[ ct load mark => reg 1 ]
[ bitwise reg 1 = (reg=1 & 0xffffffff ) ^ reg 2]
[ ct set mark with reg 1 ]
As you can see I have netlink linearization part working, don't know yet
when I will start working on kernel part (or testing of this thing for
that matter ...).
