the drivers for Chelsio would be cxgb, cxgb3 or cxgb4 atm they are not in the 3.2 package for 3615 (no one asked for them, nerver heard the name and thouht they are exotic and left them to add later)
yesterday i started compiling drivers for 3615 (as base for doing the same for 3617 and 916+)
as they are in the kernel i can easyly add them to the lsit of drivers to compile, they seem to need firmware, have to look for the files then
i can do 916+ next (before 3617) so maybe in a few hours i will have the extra.lzma with your drivers for 916+ (3615 was finished and i already started adding them as i want all 3 packages to be the same)
i will send you a pm with the link, would be nice if someone tested it with real hardware, i only do vm testing for 3617/916+)
the "official" release will be with a new driver list and for all 3 supported loaders in the next days
