Subject: [PATCH 09/11] net: dsa: rtl8366rb: Support fast aging
|
|
MIME-Version: 1.0
|

|
This implements fast aging per-port using the special "security"
|
|
register, which will flush any learned L2 LUT entries on a port.
|
|
|
|
The vendor API just enabled setting and clearing this bit, so
|
|
we set it to age out any entries on the port and then we clear
|
|
it again.
