I was wondering how come the listed media types supported by sk(4) and em(4) is only 1000BaseSX. Even for single mode 1000BaseLX NICs such as sk 9841 and Intel PWLA8490LX, ifconfig show the media type as 1000BaseSX. Though the NIC appears to operate in single mode connected to a LX switch port ok. From what I can understand SX supports only multimode fibre and LX supports both. How come there isn't 1000BaseLX for a displayed media type, and is it really single mode? thanx - steve
