vppinfra: improve clocks_per_second convergence
Apply exponential smoothing to the clock rate update calculation in clib_time_verify_frequency(), with a half-life of 1 minute and a sampling frequency of 16 seconds. Within 5 minutes or so, the calculation converges With each rate recalculation: reset total_cpu_time based on the kernel timebase delta since vpp started, and the new clock rate Improve the "show clock [verbose]" debug CLI command. BFD echo + echo fail tests marked off until the BFD code can be reworked a bit. Type: fix Signed-off-by: Dave Barach <dave@barachs.net> Change-Id: I24e88a78819b12867736c875067b386ef6115c5c
