From: wenxu <wenxu@ucloud.cn>

This series patch support more expr and obj offload: 
fw_nedev, set payload, tunnel encap/decap action,
tunnel meta match, objref 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 ]
  [ cmp eq reg 1 0x00000008 ]
  [ payload load 4b @ network header + 16 => reg 1 ]
  [ cmp eq reg 1 0x0700000a ]
  [ tunnel load id => reg 1 ]
  [ cmp eq reg 1 0x000003e8 ]
  [ tunnel load tun_dst => reg 1 ]
  [ cmp eq reg 1 0xaca8984b ]
  [ tunnel load tun_src => reg 1 ]
  [ cmp eq reg 1 0xaca898f1 ]
  [ objref type 6 name decap ]
  [ immediate reg 1 0x00005452 0x00007512 ]
  [ 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 ]
  [ immediate reg 1 0x0000000f ]
  [ fwd sreg_dev 1 ]
