testcase
Product: DPDK
Version: unspecified
Hardware: All

Target Milestone: ---
There is a bug introduced by:
Commit 066f3d9cc21c ("ethdev: remove callback checks from fast path")
In test case 139.4 <Rx offload per-port setting in command-line>, testpmd set
fwd csum, and only enable Rx csum offload. Meanwhile, driver like txgbe set
'dev->tx_pkt_prepare = NULL' since Tx offload is disabled. Thus
rte_eth_tx_prepare() calls null pointer cause segmentation fault in
pkt_burst_checksum_forward(), bacause NULL check was removed.
