How to create packet and send out with USDPAA

[tuyendinh]

Hi,

I am using T4240 board and I want to create arp packet with DPAA and send out interface. I am using bman_acquire function to alloc buffer to create packet, but it can not. It always segmentation fault when i use bman_acquire.

- Why is not alloc buffer with bman_acquire?

- How to create packet with USDPAA?

Thanks very much!
