Is there possible to add only counters from xdp for vlans ?
This will help me in testing.
I will take a look today at adding counters that you can dump using
bpftool. It will be a temporary solution for this xdp program only.
Same tree, kernel-tables-wip-02 branch. Compile kernel and install.
Compile samples as before.
If you give the userspace program a -t arg, it loop showing stats.
Ctrl-C to break. The xdp programs are not detached on exit.
Example:
./xdp_fwd -t 5 eth1 eth2 eth3 eth4
15:59:32: rx tx dropped skipped l3_dev fib_dev
index 3: 901158 901158 0 18 0 0
index 4: 901159 901158 0 20 0 901139
index 10: 0 0 0 0 19 19
index 11: 0 0 0 0 901139 901139
index 15: 0 0 0 0 19 19
index 16: 0 0 0 0 901139 0
Rx and Tx counters are for the physical port.
VLANs show up as l3_dev (ingress) and fib_dev (egress).
dropped is anytime the xdp program returns XDP_DROP (e.g., invalid packet)
skipped is anytime the program returns XDP_PASS (e.g., not ipv4 or ipv6,
local traffic, or needs full stack assist).
recompiled new version but:
./xdp_fwd enp175s0f0 enp175s0f1
libbpf: failed to create map (name: 'stats_map'): Operation not permitted
libbpf: failed to load object './xdp_fwd_kern.o'
