Subject: [PATCH 43/57] net-next: mediatek: enable special tag indication for
|
|
PDMA
|
|
|
|
The Ingress special tag indication was only enabled for QDMA and not PDMA.
|
|
Properly initialize the STAG bit. This broke HW NAT and Qos from working
|
|
for traffic coming in via a DSA device. The PPE failed to properly parse
|
|
the traffic as it was not expecting the special tag.
|
