Hi,

I was wondering if there is any chance intel will support Gore sfp+
copper cables in the near future.
The thing is the Gore passive cables are complaint with the SFF-8431
standard but yet the Intel driver seems to find the cable unsupported.

Linux kernel 2.6.33.2 with latest intel driver 2.0.72.4.
