Re: [RFC PATCH net-next 0/6] tc-taprio offload for SJA1105 DSA

- Configuring the switch over SPI cannot apparently be done from this
  ndo_setup_tc callback because it runs in atomic context. I also have
  some downstream patches to offload tc clsact matchall with mirred
  action, but in that case it looks like the atomic context restriction
  does not apply.

There have been similar problems in the past. We can probably have the
DSA layer turn it into a notifier. Look at the dsa_port_mdb_*
functions for example.
