[dpdk-stable] [PATCH 19.11.9 2/3] net/hns3: fix processing Tx offload flags

[Min Hu (Connor)]

From: Chengchang Tang <tangchengchang at huawei.com>

[ upstream commit a1d0caa92c7fe43cef7a9f6ac4772e0eecd4a011 ]

Currently, if the PKT_TX_TCP_SEG and PKT_TX_TCP_CKSUM offload flags set
in the same time, hns3 PMD can not process the descriptors correctly.

This patch fixes it by adding the processing of this situation.
