This series patch support more expr and obj offload:
fw_nedev, set payload, tunnel encap/decap action,
tunnel meta match, objref offload
Keep the action data in reg through immedidate offload
The follwing is the test sample:
# nft add table netdev firewall
# nft add tunnel netdev firewall encap tunid 1000 tundst 0xf198a8ac tunsrc 0x4b98a8ac tunrelease 0
# nft add tunnel netdev firewall decap tunid 0 tundst 0 tunsrc 0 tunrelease 1
# nft add chain netdev firewall aclout { type filter hook ingress device mlx_pf0vf0 priority - 300 \; }
# nft --debug=netlink add rule netdev firewall aclout ip daddr 10.0.1.7 @ll,0,48 set 0x00002e9ca06e2596 @ll,48,48 set 0xfaffffffffff tunnel name encap fwd to gretap
[ meta load protocol => reg 1 ]
[ cmp eq reg 1 0x00000008 ]
[ payload load 4b @ network header + 16 => reg 1 ]
[ cmp eq reg 1 0x0701000a ]
[ immediate reg 1 0x6ea09c2e 0x00009625 ]
[ payload write reg 1 => 6b @ link header + 0 csum_type 0 csum_off 0 csum_flags 0x0 ]
[ immediate reg 1 0xfffffffa 0x0000ffff ]
[ payload write reg 1 => 6b @ link header + 6 csum_type 0 csum_off 0 csum_flags 0x0 ]
[ objref type 6 name encap ]
[ immediate reg 1 0x00000019 ]
[ fwd sreg_dev 1 ]
# nft add chain netdev firewall aclin { type filter hook ingress device gretap priority - 300 \; }
# nft --debug=netlink add rule netdev firewall aclin ip daddr 10.0.0.7 tunnel tunid 1000 tunnel tundst 172.168.152.75 tunnel tunsrc 172.168.152.241 tunnel name decap @ll,0,48 set 0x0000525400001275 @ll,48,48 set 0xfaffffffffff fwd to mlx_pf0vf0
[ meta load protocol => reg 1 ]
