Hey Net -
In probably a poor, cheap choice, I picked up a TP-Link TL-SG2008 =
Desktop Smart Switch, which supports LACP/802.3ad. I=92m currently =
running 10.1-STABLE r274577 on the machine I=92m testing with. I=92m =
testing right now with just 1 port (two ports didn=92t work either.).=20

Not sure if the attachment will work to the list, but here is a pcap =
attached em1 (sudo tcpdump -i em1 -s 0 -w lacp.pcap). Attaching to the =
lagg0 with tcpdump, filters out the freebsd=92s LACP packets, but still =
sees the TP-Link=92s packets.=20
