I need to allow RTP packet on my network, I want to filter than =
RTP=A1=AFs
payload type field(7bit) value.

xx xx xx xx xx xx xx xx xx xx xx xx xx xx xx xx

xx xx xx xx xx xx xx xx xx xx xx xx xx xx xx xx

xx xx xxxx mp pp pp pp xx xx xx xx xx xx xx xx

8byte is UDP header=20

m is Maker filter

p pp pp pp is 7bit Payload type

I want to Payload type value filtering (Ex MP2T Payload type value is =
33)

Could someone give me a tip on how should tc filter look like ?
