Subject: [PATCH] net/hns3: fix processing Tx offload flags
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.
Fixes: fb6eb9009f41 ("net/hns3: fix Tx checksum with fixed header length")
