Hello, I have a set of pairs of MAC address and mask: aa:bb:cc:dd:ee:ff 00:ff:ff:ff:ff:ff aa:bb:cc:dd:ee:ff 00:ff:ff:ff:ff:00 ... I want to apply a mask to source MAC from the packet, and then compare the result with the MAC from the pair. I can do it like so: nft add table t nft add chain t c nft --debug=netlink add rule ip t c ether saddr and aa:bb:cc:dd:ee:ff 00:ff:ff:ff:ff:00 ip t c [ meta load iiftype => reg 1 ] [ cmp eq reg 1 0x00000001 ] [ payload load 6b @ link header + 6 => reg 1 ] [ bitwise reg 1 = (reg=1 & 0xddccbbaa 0x0000ffee ) ^ 0x00000000 0x00000000 ] [ cmp eq reg 1 0xffffff00 0x000000ff ] ... But I have to create a new rule for each pair. Is there any workarounds to use sets?
