Merge branch 'selftests-assortment-of-fixes'
Petr Machata says: ==================== selftests: Assortment of fixes This is a loose follow-up to the Kernel CI patchset posted recently. It contains various fixes that were supposed to be part of said patchset, but didn't fit due to its size. The latter 4 patches were written independently of the CI effort, but again didn't fit in their intended patchsets. - Patch #1 unifies code of two very similar looking functions, busywait() and slowwait(). - Patch #2 adds sanity checks around the setting of NETIFS, which carries list of interfaces to run on. - Patch #3 changes bail_on_lldpad() to SKIP instead of FAILing. - Patches #4 to #7 fix issues in selftests. - Patches #8 to #10 add topology diagrams to several selftests. This should have been part of the mlxsw leg of NH group stats patches, but again, it did not fit in due to size. ==================== Link: https://lore.kernel.org/r/cover.1712940759.git.petrm@nvidia.com Signed-off-by: Paolo Abeni <pabeni@redhat.com>
