[dpdk-dev] [PATCH v2] examples/l2fwd_fork: fix message pool init

[Xueming Li]

Some invalid callback functions are provided to rte_pktmbuf_pool_init()
without their associated data causing a segmentation fault when the
function tries to use it. In this example, those callbacks are not
necessary, they can be safely replaced by NULL pointers.

Fixes: 95e8005a56e8 ("examples/l2fwd_fork: new app")
