Subject: RE: [PATCH net-next v2 2/2] flow_offload: reject offload for all
 drivers with invalid police parameters

Since almost all the drivers that support to offload police action make the similar validation, if it make sense to add the validation in the file of flow_offload.h or flow_offload.c?
Then the other drivers do not need to make the similar validation.
WDYT?
