Also have problems with in-tree if_re
After upgrade 12.3 -> 14.0 it started to loose connectivity every ~10-30
minutes, for 0.5-10 minutes ... wich is pity, does not depends much on network
load (as minimum small load vs huge load).
Frankly speaking, even on 12.x sometimes (quite rarely) there was such looses
of connectivity, but very rare.
no any "watchdog timeouts" - just lost of connectivity, I guess

somehow ping which was run after recover:

looks like packets was buffered somewhere
Also have such in logs after recovering:
Mar 17 17:33:49 srv kernel: Limiting open port RST response from 1346 to 187
packets/sec
looks like all "stalled" TCP streams packates was delivered and got RSTs fired
back.
turning on debug on interface - did not provide any new diagnostics
ifconfig re0 -tso -tso4 -tso6 -vlanhwcsum -vlanhwtso -rxcsum -txcsum
- did not helped as well (on 12.x -vlanhwtso probably helped)
what was helped - switchover to the port net/realtek-re-kmod
