In particular the kernel version does consider the divisor when folding.
That's correct. And so does tc. What's the matter?
tc assumes 256 when undefined. Maybe man page needs to be
updated to state we need divisor specified otherwise default
is 256.
Two examples that currently work, if you can try them:
Both lack information about the used hashkey and divisor.
Most used scheme:
---
tc filter add dev $DEV parent 999:0 protocol ip prio 10 u32 \
ht 2:: \
sample ip protocol 1 0xff match ip src 1.2.3.4/32 flowid 1:10 \
action ok
----
htid before: 0x201000
htid after: 0x201000
Ok, this is the most common use-case. So we are good.
