Subject: [PATCH 10/11] net: dsa: rtl8366rb: Support setting STP state
|
|
MIME-Version: 1.0

This adds support for setting the STP state to the RTL8366RB
|
|
DSA switch. This rids the following message from the kernel on
|
|
e.g. OpenWrt:
|
|
|
|
DSA: failed to set STP state 3 (-95)
|
|
|
|
Since the RTL8366RB has one STP state register per FID with
|
|
two bit per port in each, we simply loop over all the FIDs
|
|
and set the state on all of them.
