[AusNOG] Megaport - Link Negotiation

[Damian Guppy]

I would assume it's actually a function of the SFP module and not of the
router/switch its plugged into, since as has been said, you can plug a 1G
SFP module into a SFP+ slot and it works at 1G. The SFP+ module would just
report its operating as a 1G module.
