selftests: skbedit_priority: Test counters at the skbedit rule (2a0b1307) · Commits · 戴 / test

Currently the test checks the observable effect of skbedit priority: queueing of packets at the correct qdisc band. It therefore misses the fact that the counters for offloaded rules are not updated. Add an extra check for the counter. Signed-off-by:
