Jiri says:

There are some limitations for TC matchall classifier offload that are
given by the mlxsw HW dataplane. It is not possible to do sampling on
egress and also the mirror/sample vs. ACL (flower) ordering is fixed. So
check this and forbid to offload incorrect setup.

Jiri Pirko (9):
  mlxsw: spectrum_matchall: Restrict sample action to be allowed only on
    ingress
  mlxsw: spectrum_flower: Expose a function to get min and max rule
    priority
  mlxsw: spectrum_matchall: Put matchall list into substruct of flow
    struct
  mlxsw: spectrum_matchall: Expose a function to get min and max rule
    priority
  mlxsw: spectrum_matchall: Forbid to insert matchall rules in collision
    with flower rules
  mlxsw: spectrum_flower: Forbid to insert flower rules in collision
    with matchall rules
  selftests: mlxsw: rename tc_flower_restrictions.sh to
    tc_restrictions.sh
  selftests: mlxsw: tc_restrictions: add test to check sample action
    restrictions
  selftests: mlxsw: tc_restrictions: add couple of test for the correct
    matchall-flower ordering
