Subject: Re: [PATCH net,v4] net: flow_offload: skip hw stats check for
 FLOW_ACTION_HW_STATS_DONT_CARE

From: Pablo Neira Ayuso <pablo@...filter.org>

> 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.

> TCA_ACT_HW_STATS_* maintains the 1:1 mapping with FLOW_ACTION_HW_STATS_*
> except by disabled which is mapped to FLOW_ACTION_HW_STATS_DISABLED
> (this is 0 in tc). Add tc_act_hw_stats() to perform the mapping between
> TCA_ACT_HW_STATS_* and FLOW_ACTION_HW_STATS_*.
