bridge: restore br_setlink back to original
This is revert of: commit 68e331c785b8 ("bridge: offload bridge port attributes to switch asic if feature flag set") Restore br_setlink back to original and don't call into SELF port driver. rtnetlink.c:bridge_setlink() already does a call into port driver for SELF. bridge set link cmd defaults to MASTER. From man page for bridge link set cmd: self link setting is configured on specified physical device master link setting is configured on the software bridge (default) The link setting has two values: the device-side value and the software bridge-side value. These are independent and settable using the bridge link set cmd by specifying some combination of [master] | [self]. Furthermore, the device-side and bridge-side settings have their own initial value, viewable from bridge -d link show cmd. Restoring br_setlink back to original makes rocker (the only in-kernel user of SELF link settings) work as first implement: two-sided values. It's true that when both MASTER and SELF are specified from the command, two netlink notifications are generated, one for each side of the settings. The user-space app can distiquish between the two notifications by observing the MASTER or SELF flag.
