We hit an issue,a VM Through the snat of the centralized gateway, it is
found that there are some not offload flows on the centralized gateway.
flow entries and tc rules are as follows
ufid:8e0f1bc7-aafe-4edf-adf4-daee5ad19b0d,
skb_priority(0/0),tunnel(tun_id=0x1,src=172.31.1.21,dst=172.31.5.23,ttl=0/0,tp_dst=6081,geneve({class=0x102/0,type=0x80/0,len=4,0x10002/0}),flags(+key)),skb_mark(0/0),ct_state(0x21/0x29),ct_zone(0/0),ct_mark(0/0),ct_label(0/0),recirc_id(0x3a),dp_hash(0/0),in_port(genev_sys_6081),packet_type(ns=0/0,id=0/0),eth(src=00:00:00:00:00:00/00:00:00:00:00:00,dst=00:00:00:00:00:00/00:00:00:00:00:00),eth_type(0x0800),ipv4(src=

We use the Mellanox CX6 Dx card , SR IOV and offload tc to hardware .
What went wrong?
