Subject: Failing to attach bond(created with two interfaces from different
 NICs) to a bridge

Hello Jiri,

After the following set of upstream commits, the user fails to attach
a bond to the bridge, if the user creates the bond with two interfaces
from different bnxt_en NICs. Previously bnxt_en driver does not
advertise the switch_id for legacy mode as part of
ndo_get_port_parent_id cb but with the following patches, switch_id is
returned even in legacy mode which is causing the failure.

---------------
7e1146e8c10c00f859843817da8ecc5d902ea409 net: devlink: introduce
devlink_compat_switch_id_get() helper
6605a226781eb1224c2dcf974a39eea11862b864 bnxt: pass switch ID through
devlink_port_attrs_set()
56d9f4e8f70e6f47ad4da7640753cf95ae51a356 bnxt: remove
ndo_get_port_parent_id implementation for physical ports
----------------

As there is a plan to get rid of ndo_get_port_parent_id in future, I
think there is a need to fix devlink_compat_switch_id_get() to return
the switch_id only when device is in SWITCHDEV mode and this effects
all the NICs.

Please let me know your thoughts. Thank you.

Thanks,
Vasundhara
