Re: [PATCH net-next 2/2] net: dsa: mv88e6xxx: add support for credit based shaper

[Luke Howard]

Hi Cedric,

We sent RFC patches for mv88e6xxx support for both MQPRIO [1] and CBS [2] last year. (We have since made a few small changes which can be found in our working tree at [3].)

We have been using these patches successfully for the past year with our SRP stack [4] on a custom board with a 88E6352. The CBS and MQPRIO patches remain unsubmitted because we also needed extend the Netlink API and software bridge with a flag indicating a FDB/MDB entry is managed by SRP.

I would be happy to work together to harmonise our patches to avoid duplicated effort.

Cheers,
Luke
