From 68d9cea594b5da185e5b048e9b4fa0dadeafe88a Mon Sep 17 00:00:00 2001 From: Petr Machata Date: Sat, 30 Jun 2018 02:46:05 +0200 Subject: [PATCH] selftests: forwarding: lib: Parameterize NUM_NETIFS in two functions setup_wait() and tc_offload_check() both assume that all NUM_NETIFS interfaces are relevant for a given test. However, the scale test script acts as an umbrella for a number of sub-tests, some of which may not require all the interfaces. Thus it's suboptimal for tc_offload_check() to query all the interfaces. In case of setup_wait() it's incorrect, because the sub-test in question of course doesn't configure any interfaces beyond what it needs, and setup_wait() then ends up waiting indefinitely for the extraneous interfaces to come up. For that reason, give setup_wait() and tc_offload_check() an optional parameter with a number of interfaces to probe. Fall back to global NUM_NETIFS if the parameter is not given.
