And it does appear to offer support for WoL. They (Intel) have functions in their if_em.c source file that sets up the WoL. However, there is no IFCAP_WOL define in Intel's code, so maybe it does not interface with ifconfig correctly at this point? I don't know. I was hoping to get some pointers on where to look or how to tell. Also, I'm not opposed to adding the WoL support - I'm not too bad in C - I've just never written a FreeBSD device driver and the excellent post by Stefan Sperling (referenced from the WoL wiki) seems to be too far out of date. The wiki itself states: "Note that the obsolete ioctl-based configuration approach is discussed there, but ifcaps should be used instead." So, not knowing anything about either ioctl-based or ifcaps config, I can't find any resources on how to get started in the right direction (hence my post to hackers). Also, if Intel's driver code works, it seems to me that it makes more sense to use their code for em devices, no? Is there a copyright problem with that? Matthew
