My SOHO router actually has a minor regression with Intel NICs:igb0: Watchdog timeout (TX: 0 desc avail: 979 pidx: 106) -- resetting igb0: link state changed to DOWN igb0: link state changed to UP igb1: Watchdog timeout (TX: 7 desc avail: 980 pidx: 543) -- resetting igb1: link state changed to DOWN igb1: link state changed to UP This never happened on this machine for 10 years. It is just a single link loss for ~ 24 hours, but the traffic on this router is really minimal.
The watchdog was not working for years. Commit https://cgit.freebsd.org/src/commit/?id=69c3e0de01c1938792d319f18ba0a9ffa60dfa96 restores the functionality.net.iflib.timer_default is 4 by default (that's number of timer intervals). If your hardware delays the update of the state longer than that, you can increase that value. I have one slow and old hardware which needs the kick by the watchdog, and the setting was tuned on that. Your more modern hardware (igb should be way more modern than what this was tuned on) should complete that stuff much faster, so the initial expectation is, that there really is an issue.
