selftests/tc-testing: Fix SFB db test
[ Upstream commitb39d8c41c7
] Setting very small value of db like 10ms introduces rounding errors when converting to/from jiffies on some kernel configs. For example, on 250hz the actual value will be set to 12ms which causes the test to fail: # $ sudo ./tdc.py -d eth2 -e 3410 # -- ns/SubPlugin.__init__ # Test 3410: Create SFB with db setting # # All test results: # # 1..1 # not ok 1 3410 - Create SFB with db setting # Could not match regex pattern. Verify command output: # qdisc sfb 1: root refcnt 2 rehash 600s db 12ms limit 1000p max 25p target 20p increment 0.000503548 decrement 4.57771e-05 penalty_rate 10pps penalty_burst 20p Set the value to 100ms instead which currently seem to work on 100hz, 250hz, 300hz and 1000hz kernel configs.
