Russell King f10fcbcf91 sfp: improve support for direct-attach copper cables 
Improve the support for direct-attach copper so that we avoid kernel
warning messages, and report the appropriate PORT_DA type to userspace.
Direct Attach cables can use a number of protocols depending on their
range of speeds.
