resend same queue tx burst

[Lokesh Chakka]

hi,

I've written a small piece of code(PFA) for sending packets. I'm facing two
issues here :
In rte_pktmbuf_append, if I pass dev_info.max_mtu, it's failing. however,
if I set 1500, it is able to allocate.
Is there a way to allocate dev_info.max_mtu(9702) ?

I want to send the same queue multiple times using rte_eth_tx_burst. First
time, it is sending. But the second time it is giving an error.

Can someone help me understand?

Thanks & Regards
