Honycomb LX2K board has 4 SFP+ sockets. I was led to believe these were somewhat plug-and-play. Maybe not hotplug, but perhaps coldplug
Amazon sent me a pair of Ipolex ASF-10G-T (Odd, because I paid for the gigabit equivalent, but apparently they do work at slower speeds).
I see nothing new in dmesg. The only thing I can find about SFP+ is is mentions of kernel module ixgbe “ixgbe.allow_unsupported_sfp=1” - and that loads, but does not seem to find any hardware.
What sort of dmesg / dev entries should I expect to see?
EDIT: It struck me that it might be a pcie limitation, having a radeon installed, but the LX2160A has 24 lanes, so I’m guessing that’s not it.
