Re: [E1000-devel] ixgbe for 10 GbE SFP+ without CS4227 phy
I'm afraid that might need the attention of some of our HW engineers and I'd have to play telephone, passing questions back and forth. That just gets frustrating. The official support model is to use IPS & HSD. Plus, if it's a custom design we have NDAs in place and I don't want to get into all that.
