Subject: [PATCH] extensions: hashlimit: Fix tests with HZ=1000
In an attempt to fix for failing hashlimit tests with HZ=100, the
expected failures were changed so they are expected to pass and the
parameters changed to seemingly fix them. Yet while the new parameters
worked on HZ=100 systems, with higher tick rates they didn't so the
observed problem moved from the test failing on HZ=100 to failing on
HZ=1000 instead.
Kernel's error message "try lower: 864000000/5" turned out to be a red
herring: The burst value does not act as a dividor but a multiplier
instead, so in order to lower the overflow-checked value, a lower burst
value must be chosen. Inded, using a burst value of 1 makes the kernel
accept the rule in both HZ=100 and HZ=1000 configurations.
Fixes: bef9dc575625a ("extensions: hashlimit: Fix tests with HZ=100")
