Merge branch 'selftests-mirror-to-gretap-with-team'
Petr Machata says: ==================== A test for mirror-to-gretap with team in UL packet path This patchset adds a test for "tc action mirred mirror" where the mirrored-to device is a gretap, and underlay path contains a team device. In patch #1 require_command() is added, which should henceforth be used to declare dependence on a certain tool. In patch #2, two new functions, team_create() and team_destroy(), are added to lib.sh. The newly-added test uses arping, which isn't necessarily available. Therefore patch #3 introduces $ARPING, and a preexisting test is fixed to require_command $ARPING. In patches #4 and #5, two new tests are added. In both cases, a team device is on egress path of a mirrored packet in a mirror-to-gretap scenario. In the first one, the team device is in loadbalance mode, in the second one it's in lacp mode. (The difference in modes necessitates a different testing strategy, hence two test cases instead of just parameterizing one.) ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
