selftests: txtimestamp: add flag for timestamp validation tolerance. 2020-07-30T23:38:51+00:00 Jian Yang jianyang@google.com 2020-07-27T21:14:38+00:00 d3239425351a219ec779488ffb125352449c4106 The txtimestamp selftest sets a fixed 500us tolerance. This value was arrived at experimentally. Some platforms have higher variances. Make this adjustable by adding the following flag: -t N: tolerance (usec) for timestamp validation.
