Subject: [PATCH] networkd-link: Receive LLDP on Bridge slaves not master
|
||
|
|
(#5995)
|
||
|
|
|
||
|
|
LLDP should be received on bridge slaves as they're the entities
|
||
|
|
directly connected to a peer. Receiving LLDP on the bridge device makes
|
||
|
|
little sense, Linux by default even filters out LLDP going onto the
|
||
|
|
bridge device.
|
||
|
|
|
||
|
|
Flip the current logic, receive LLDP on bridge slaves don't listen for
|
||
|
|
them on the bridge itself.
|
||
|
|
(cherry picked from commit 764febc23ee9a22fa64981adb0be901f964df93d)
