Subject: Re: KSZ9477 HSR Offloading

> Anyway, do you have any suggestions for debugging this?

Could you dump the fdb tables. `bridge fdb show`. Has the local device
learned the MAC addresses of the other devices? I'm making a big
assumption here, that HSR makes use of the FDB to decide the egress
interface. If there is no entry in the table, the hardware could be
dropping the frame. Rather than drop, it should probably forward to
the CPU, and then software HSR will determine the egrees
interface. Once the peer has replied, the FDB should get populated,
and then hardware should be able to do all the work without Linux?
