            Bug ID: 1834
           Summary: [dpdk-25.11-rc2] Segmentation fault in Rx offload
                    testcase
           Product: DPDK
           Version: unspecified
          Hardware: All
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: Normal
         Component: testpmd
          Assignee: dev at dpdk.org
          Reporter: jiawenwu at trustnetic.com
  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.
