This patch adds FLOW_ACTION_HW_STATS_DONT_CARE which tells the driver
that the frontend does not need counters, this hw stats type request
never fails. The FLOW_ACTION_HW_STATS_DISABLED type explicitly requests
the driver to disable the stats, however, if the driver cannot disable
counters, it bails out.
Remove BUILD_BUG_ON since TCA_ACT_HW_STATS_* don't map 1:1 with
FLOW_ACTION_HW_STATS_* anymore. Add tc_act_hw_stats() to perform the
mapping between TCA_ACT_HW_STATS_* and FLOW_ACTION_HW_STATS_*
Fixes: 319a1d19471e ("flow_offload: check for basic action hw stats type")

This is a follow up after "net: flow_offload: skip hw stats check for
FLOW_ACTION_HW_STATS_DISABLED". This patch restores the netfilter hardware
offloads.

TCA_ACT_HW_* are bits. There can be a combination of those according
to the user request. For 2 bits, it is not problem, but I have a
patchset in pipes adding another type.
Then you need to have 1:1 mapping in this array for all bit
combinations. That is not right.
How about putting DISABLED to the at the end of enum
flow_action_hw_stats? They you can just map 0 here to FLOW_ACTION_HW_STATS_DISABLED
as an exception, but the bits you can take 1:1.

Another possibility is to remove this mapping code is to update tc
UAPI to get it aligned with this update.
This UAPI is only available in the few 5.7.0-rc kernel releases,
I think only developers are using this at this stage?

Hmm, I think that TC-wise, the UAPI as is makes perfect sense. There is
no don't care. Each bit allows to indicate user what he is interested
in.
I would prefer to convert to flow_offload (as we do anyway) in a format
that is comfortable for flow_offload (given the fact it is used not only
for TC).
Did you check the solution I suggested? Above. Seems to be quite
straightforward.
