Re: v6.43rc [release candidate] is released!

model: CRS317-1G-16S+
release: v6.43rc44

we use some ports with non-10G SFPs (ie 1G-SX and 1G-TX modules with fiber and copper).

those modules get auto negotiation 'incomplete', while claiming the link is ok but no working datatransmission can be established.

Re: CRS 317 support 802.1ad QinQ

As other people wonder - Are we/Have we gotten hardware support for QinQ?
Doesn't look like it, though the Marvell 98DX8216 is a metro chipset (marvell's words) which would suggest 802.1ad should be available at the HW level.
But my guess is we won't see this with this HW.
