Revision f7017cafcdd7574680fc7faabcb73f91172a14ab authored by Davide Caratti on 09 May 2018, 16:45:42 UTC, committed by David S. Miller on 10 May 2018, 21:28:02 UTC 
tc-testing: fix tdc tests for 'bpf' action
 
- correct a typo in the value of 'matchPattern' of test 282d, potentially
 causing false negative
- allow errors when 'teardown' executes '$TC action flush action bpf' in
 test 282d, to fix false positive when it is run with act_bpf unloaded
- correct the value of 'matchPattern' in test e939, causing false positive
 in case the BPF JIT is enabled
