To work around it, I've done: ifconfig re0 down=20 ifconfig re0 -tso ifconfig re0 up ( and give it a go 15 seconds ) and dhclient should do it's t= hing. The only way I've been able to get -tso and DHCP together at boot is to plac= e the re0 in a lagg group. Hope that helps, Cheers, -bp "Remember - no matter where you go, there you are." - Buckaroo Banzai > On Dec 9, 2014, at 8:36 AM, Shawn Webb wrote: >=20 > Hey FreeBSD Peeps, >=20 > I just got a new laptop (Lenovo Y50-70) that has a Realtek RTL8111/8168B > NIC in it.
