Hi all,
AFAICT there is no code that attempts to get the value of the attribute
SWITCHDEV_ATTR_ID_PORT_BRIDGE_FLAGS while it is used with
switchdev_port_attr_set().
This is effectively no doing anything and it can slow down future work
that tries to make modifications in these areas so remove that.
David, there should be no dependency with previous patch series, but
again, feedback from Ido and Jiri would be welcome in case this was
added for a reason.
Thanks!

It was originally used by:
switchdev_port_bridge_getlink()
removed by:
commit 29ab586c3d83f81c435e269cace9a1619afb5bbd
Author: Arkadi Sharshevsky <[email protected]>

net: switchdev: Remove bridge bypass support from switchdev
So these are just leftovers. Let's flush them.

Yes, I will be working on a v5 which addresses Ido's feedback in the

Ok, is there going to be another respin of that switchdev_ops removal
series?

David, looks like I managed to introduce a build failure with
rocker_ofdpa.c, sorry about that, I will send a follow-up immediately.
