In the error situation, ifconfig reports “Link up” and ethtool reports “Link detected” but ping, etc, to any remote destination ibb. It is greatly appreciated.

I’d like to test this a bit more and target this for the next update in the event this introduces a regression igbb don’t expect and this is no worse than what we shipped in 5.
