[Cerowrt-devel] [Bloat] DC behaviors today

[Pedro Tumusok]

Looking at chipsets coming/just arrived from the chipset vendors, I think
we will see CPE with 10G SFP+ and 802.11ax Q3/Q4 this year.
Price is of course a bit steeper than the 15USD USB DSL modem :P, but
probably fits nicely for the SMB segment.
