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
