em(4) cannot maintain link in 12.0-STABLE

I have two NICs in a machine which acts as a gateway, and with the upgrade from 11-STABLE to the latest 12.0-STABLE tree (r346473), neither em(4) based NIC will maintain a connection. The behavior is similar to what is described in the last couple comments of this ticket: https://bugs.freebsd.or

Peculiar failure of re(4) to active a link after a RAM upgrade

ed. I'm really clueless as to what would even be happening underneath the covers here, and would appreciate any pointers in the right direction for debugging here :) Cheers, -R Tyler Croy -- GitHub: https://github.com/rtyler Twitter: https://twitter.com/agentdero signature.asc Description: PGP signature
