Subject: [PATCH] lldpad: system capability incorrect advertised as station
|
|
|
ee47b4 |
only
|
|
|
ee47b4 |
|
|
|
ee47b4 |
Fix system capability TLV on switch. On our switches we have found
|
|
|
ee47b4 |
that the system capability was being advertised as Station Only. This
|
|
|
ee47b4 |
patch changes the capability to Bridge.
