Subject: [PATCH 13/96] [netdrv] bnxt: Implement ndo_get_port_parent_id()
Message-id: <610919f3c6de0c97b6b178b7f643f6c81a2de24a.1570027456.git.jtoppins@redhat.com>
Patchwork-id: 276436
O-Subject: [RHEL-8.2 PATCH 05/78] bnxt: Implement ndo_get_port_parent_id()
Bugzilla: 1724766
RH-Acked-by: John Linville <linville@redhat.com>
RH-Acked-by: Jarod Wilson <jarod@redhat.com>
BNXT only supports SWITCHDEV_ATTR_ID_PORT_PARENT_ID, which makes it a
great candidate to be converted to use the ndo_get_port_parent_id() NDO
instead of implementing switchdev_port_attr_get(). The conversion is
straight forward here since the PF and VF code use the same getter.
Since bnxt makes uses of switchdev_port_same_parent_id() convert it to
use netdev_port_same_parent_id().
