Application uses different pool to allocate direct and indirect
mbufs which are further spliced together to consturct a fragmented
packet and same is transmitted over the port which is configured
with DEV_TX_OFFLOAD_MBUF_FAST_FREE enabled i.e. all segments
must belong to the same pool. But constructed packet violates
the conditions.

So fixing DEV_TX_OFFLOAD_MBUF_FAST_FREE flag during device
configuration.
