Did something change from 5.2.1 to 5.3? In 5.2.1 I used to have a config where the parent device, em(4), didn't have an IP, and the vlan dev had the IP address. (yes, the parent device was "UP") I then configured the trunk (on the switch) to have a native vlan of something other than the vlan interface's vlan. This worked. Now, in 5.3, the only thing I can get working is to configure the em0 int with the IP, and set the trunk to have the native vlan corresponding to that IP. Weird. Also, is there a way to stop em(4) from stripping dot1q tags in hardware? I'd like to see them with tcpdump. What kind of a performance hit does this involve? Thanks :) -Charlie
