tc-tests: Update tc police action tests for tc buffer size rounding fixes. 2025-03-19T17:40:24+00:00 Jonathan Lennox jonathan.lennox42@gmail.com 2025-03-12T17:48:04+00:00 756f88ff9c6ae3d059180813102610c39ea99c27 Before tc's recent change to fix rounding errors, several tests which specified a burst size of "1m" would translate back to being 1048574 bytes (2b less than 1Mb). sprint_size prints this as "1024Kb". With the tc fix, the burst size is instead correctly reported as 1048576 bytes (precisely 1Mb), which sprint_size prints as "1Mb". This updates the expected output in the tests' matchPattern values to accept either the old or the new output.
