selftests: mlxsw: Reduce running time using offload indication

# SPDX-License-Identifier: GPL-2.0

# Test for resource limit of offloaded flower rules. The test adds a given

# number of flower matches for different IPv6 addresses, then generates traffic,

# and ensures each was hit exactly once. This file contains functions to set up

# a testing topology and run the test, and is meant to be sourced from a test

# number of flower matches for different IPv6 addresses, then check the offload

# indication for all of the tc flower rules. This file contains functions to set

# up a testing topology and run the test, and is meant to be sourced from a test

# script that calls the testing routine with a given number of rules.
