From: Mike Maloney <malo...@google.com> Add software rx timestamps for TCP, and a test to ensure consistency of behavior between IP, UDP, and TCP implementation.
Changes since v1: -Initialize tss->ts[1] to 0 if caller requested any timestamps. -Fix test case to validate that tss->ts[1] is zero. -Fix tests to actually use a raw socket. -Fix --tcp flag to work on the test.
