I am modifying l2fwd example to inject additional packets.
I am successfully allocating mbufs with rte_pktmbuf_alloc, but weird
problems started to occur (feels likes concurrency problems).
I enabled DEBUGs in config file and now my application started crashing on:
PANIC in rte_mbuf_sanity_check:
bad ref cnt

Aborted (core dumped)
Maybe I am allocating mbufs from incorrect core?
But which core should I use? (Other packets are allocated automatically by
PMD)
Thanks
