Subject: [PATCH net-next 0/3,v2] flow_offload hardware priority fixes

Hi,

This patchset contains three updates for the flow_offload users:

1) Pass major tc priority to drivers so they do not have to
   lshift it. This is a preparation patch for the fix coming in
   patch 3/3.

2) Add a new structure to basechain objects to wrap the offload
   data. This is another preparation patch for the fix coming in
   patch 3/3.

3) Allocate priority field per rule from the commit path and
   pass it on to drivers. Currently this is set to zero and
   some drivers bail out with it, start by priority number 1
   and allocate new priority from there on. The priority field
   is limited to 8-bits at this stage for simplicity.

v2: address Jakub comments to not use the netfilter basechain
    priority for this mapping.

Please, apply, thank you.

Pablo Neira Ayuso (3):
  net: sched: use major priority number as hardware priority
  netfilter: nf_tables_offload: add offload field to basechain
  filter: nf_tables_offload: set priority field for rules
