Subject: [PATCH net-next 0/5] selftests: expand txtimestamp with new features

From: Jian Yang <[email-masked]>

Current txtimestamp selftest issues requests with no delay, or fixed 50
usec delay. Nsec granularity is useful to measure fine-grained latency.
A configurable delay is useful to simulate the case with cold
cachelines.

This patchset adds new flags and features to the txtimestamp selftest,
including:
- Printing in nsec (-N)
- Polling interval (-b, -S)
- Using epoll (-E, -e)
- Printing statistics
- Running individual tests in txtimestamp.sh

Jian Yang (5):
  selftests: txtimestamp: allow individual txtimestamp tests.
  selftests: txtimestamp: allow printing latencies in nsec.
  selftests: txtimestamp: add new command-line flags.
  selftests: txtimestamp: add support for epoll().
  selftests: txtimestamp: print statistics for timestamp events.
