Commit Message

Jonathan Toppins Aug. 10, 2022, 2:33 a.m. UTC 
This creates a test collection in drivers/net/bonding for bonding
specific kernel selftests.

The first test is a reproducer that provisions a bond and given the
specific order in how the ip-link(8) commands are issued the bond never
transmits an LACPDU frame on any of its slaves.

Signed-off-by: Jonathan Toppins <jtoppins@redhat.com>

Notes:
    v2:
     * fully integrated the test into the kselftests infrastructure
     * moved the reproducer to under
       tools/testing/selftests/drivers/net/bonding
     * reduced the test to its minimial amount and used ip-link(8) for
       all bond interface configuration

nit： maybe remove this debug comment when you post a new version?

Others looks good to me.

Thanks
