Isolate unused Ethernet and re-pick on carrier loss - #6
Merged
Conversation
Cold boot was assigning .1 to unplugged eth0 (2s carrier wait) then treating that local .1 as a foreign gateway on eth1. micronet now owns every cable iface: one up, the rest down, with a 10s carrier-loss re-apply. Co-authored-by: Cursor <cursoragent@cursor.com>
