net: dcb: application priority is per net_device (7ec79270) · Commits · 戴 / test

The app_data priority may not be the same for all net devices. In order for stacks with application notifiers to identify the specific net device dcb_app_type should be passed in the ptr. This allows handlers to use dev_get_by_name() to pin priority to net devices. Signed-off-by:
