Looking at
https://github.com/shemminger/iproute2/blob/main/misc/ss.c#L589 the ss.c
still uses proc/.

Only for legacy reasons.

ss -t for sure will use netlink first, then fallback to /proc

New counters should use netlink, please.

Andrew,

    Could you add more to your comment? The /proc was used similarly to kTLS.
Netlink is better, though, unsure how ULP stats would fit in it.

How do tools like ss(1) retrieve the protocol summary statistics? Do
they still use /proc, or netlink?
