Subject: [PATCH net-next v6 14/23] bridge: restore br_setlink back to original
Date: Sat, 9 May 2015 10:40:16 -0700 [thread overview]
Message-ID: <1431193225-807-15-git-send-email-sfeldma@gmail.com> (raw)
In-Reply-To: <1431193225-807-1-git-send-email-sfeldma@gmail.com>
From: Scott Feldman <sfeldma@gmail.com>
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].
Futhermore, 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.
