Hi,

I didn't receive the cover letter, so I'm replying on this one. :-)

This is nice. One thing is not clear to me yet. From the samples on
the cover letter:

$ tc -s filter show dev enp8s0f0_1 ingress
filter protocol ip pref 4 flower chain 0
filter protocol ip pref 4 flower chain 0 handle 0x1
  dst_mac 0a:40:bd:30:89:99
  src_mac ca:2e:a7:3f:f5:0f
  eth_type ipv4
  ip_tos 0/0x3
  ip_flags nofrag
  in_hw in_hw_count 1
        action order 1: tunnel_key  set
        src_ip 7.7.7.5
        dst_ip 7.7.7.1
        ...

$ tc -s filter show dev vxlan_sys_4789 ingress
filter protocol ip pref 4 flower chain 0
filter protocol ip pref 4 flower chain 0 handle 0x1
  dst_mac ca:2e:a7:3f:f5:0f
  src_mac 0a:40:bd:30:89:99
  eth_type ipv4
  enc_dst_ip 7.7.7.5
  enc_src_ip 7.7.7.1
  enc_key_id 98
  enc_dst_port 4789
  enc_tos 0
  ...

These operations imply that 7.7.7.5 is configured on some interface on
the host. Most likely the VF representor itself, as that aids with ARP
resolution. Is that so?

Thanks,
Marcelo
