I have downloaded the nightly image and noticed a couple of things in 3GPP2 GRE dissector.

1. The Flow Id is now showing up as 2 bytes. It should be only 1 byte. In the attached capture, for example, flow Id should have been 0x00. It shows up incorrectly as 0x007E.

2. The attribute display is a bit difficult to read. 

     > 1x SDB/HRPD DoS Indicator (Reserved)
          .000 0001 = Type: Short Data Indicator (0x01)
          Length: 0x02
          0... .... .... .... = Short Data Indicator(SDI): Reserved

     > 1x SDB/HRPD DoS Indicator (packet suitable for 1x SDB or HRPD DOS transmission)
          .000 0001 = Type: Short Data Indicator (0x01)
          Length: 0x02
          1... .... .... .... = Short Data Indicator(SDI): packet suitable for 1x SDB or HRPD DOS transmission

     > Flow Control Indicator (XOFF, INDEFINITE)
         Length: 0x02
         1... .... .... .... = Flow Control Indicator: XOFF
         .1.. .... .... .... = Duration Indicator: INDEFINITE:
   
   Unless expanded, they will look like
     > 1x SDB/HRPD DoS Indicator (Reserved)
     > 1x SDB/HRPD DoS Indicator (packet suitable for 1x SDB or HRPD DOS transmission)
     > Flow Control Indicator (XOFF, INDEFINITE)

   This will make it really easy for me in everyday debugging in the lab.

Let me know if this is OK with you.

Also, can you spare a moment and let me know how you got the PPP dissection working? I tried my best to figure out the code path but could not figure it out :-)

Thanks
Ravi

Checked in alongside some changes to the way the GRE information is
displayed and making the PPP dissector display the payload.

Hi

Attached file contains a minor fix for 3GPP2 A11 Session Update and a
set of capture files .cap and decoded .txt files.

Please apply the patch to the source tree at your convenience.

I will update the Wiki pages as soon as possible.

Thanks
Ravi
