From: Jiri Pirko Date: Wed, 24 Apr 2024 10:40:46 +0000 (+0200) Subject: selftests: forwarding: add ability to assemble NETIFS array by driver name X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=41ad836e393aa834039de48c84305dfe7d6aceef;p=linux.git selftests: forwarding: add ability to assemble NETIFS array by driver name Allow driver tests to work without specifying the netdevice names. Introduce a possibility to search for available netdevices according to set driver name. Allow test to specify the name by setting NETIF_FIND_DRIVER variable. Note that user overrides this either by passing netdevice names on the command line or by declaring NETIFS array in custom forwarding.config configuration file.
