I did a quick file download test on the LRO-enabled device (forwarding is turned on) and there's no perceive drop-off in forwarding performance. The test is very unscientific (over the Internet) as I don't have access to a local test bed where I can do more in-depth testing. Sysctl LRO stats ga

Hi, I have an HP ProLiant DL360p Gen8 server in my possession for testing, and it appears the Broadcom NetXtreme BCM5719 doesn't yet have support. I noticed someone asking about server support on freebsd-questions last month, but it didn't garner much attention. Played around with 8.3-RELEASE, 8-

Maybe another option to dhclient to have it poll the interface every 2-3 seconds to see if it has lost a link and if so, set the lease timer to be expired, and wait for it to come back and once it does, it will acquire a new address. ___ freebsd-net@freeb

Thats pretty standard for BSD and most Unixes. DHCP hands out leases for a specified period of time, so unless there is a reason to reset it, it wont. Windows does that, but it is designed more as a client / user facing OS whereas BSD is designed to run in the background silently serving you cont

I have the simplest possible DHCP setup: ifconfig_re0="DHCP" in /etc/rc.conf. When the system boots, it gets connected fine. Now, I disconnect my laptop and connect it to another network. When cable is disconnected, IP address of this interface stays the same, old one is not removed. When I p
