Merge branch 'flow_offload-hardware-priority-fixes'
Pablo Neira Ayuso says:
====================
flow_offload hardware priority fixes
This patchset contains two updates for the flow_offload users:
1) Pass the major tc priority to drivers so they do not have to
lshift it. This is a preparation patch for the fix coming in
patch #2.
2) Set the hardware priority from the netfilter basechain priority,
some drivers break when using the existing hardware priority
number that is set to zero.
v5: fix patch 2/2 to address a clang warning and to simplify
the priority mapping.
====================
