TSN Frame Preemption Test on LS1028ARDB

Hi experts,

 

I am trying to perform the Qbu test on ENETC for the LS1028ARDB board (can be found in the OpenILUG_Rev1.10.pdf file, page 88). As I have only one LS1028ARDB board, I am testing the version where MAC0 is linked to SWP0. In fact the demo works but I still have some questions:

-  Does the command "qbuset --device eno0 --preemptable 0xfe" mean that traffic class #0 or the frames in queue #0 will be preempted?

- The port with the address 90:e2:ba:ff:ff:ff shouldn't be swp0 instead of eno0, as the traffic flows from eno0 to swp0, and the option -m of pktgen_twoqueue.sh specifies the destination MAC address?

- What does the value 0x111 that we have to write at the address 0x1fc100048 correspond to? And more generally, where can I find a document which gives more information about the registers 0x1fc100048 and 0x11f18 ?

 

Thank you for your help.
