Does your DHCP server send you an MTU, perhaps? Before the interface resets, what does its MTU show? You might try creating a dhclient.conf that sets "supersede interface-mtu 0;" and see if that helps. The MTU from DHCP feature is new (see https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=206721 ) and e1000 interfaces will reset when applying the MTU.
