Howdy, I just added sff8472.h to sys/net which allows driver writers to get = information on SFF/SFP+ optics and cables across i2c more easily. Navdeep (np@) has added the relevant = code to tools/tools/cxgbetool to show how to use these values to get information from cables plugged = into NICs. Can those of you who work on the various drivers that have an I2C interface to the = cabling please look at that include file and the cxgbetool program and start adding your own code to = handle this in a similar way? It=92s a great help to those working with hardware in large data centers = when they can see things like this: trantor:~# cxgbetool t5nex0 modinfo 1 ID: SFP Vendor FINISAR CORP.
