From 1cc574c41a8e4a901b822aad9c85a07e98a7b661 Mon Sep 17 00:00:00 2001 From: Huisong Li Date: Sat, 17 Jul 2021 10:02:56 +0800 Subject: [PATCH] net/hns3: fix Tx prepare after stop In some special scenarios, such as TSO scenarios, the user layer may need to call the tx_pkt_prepare(), and then call tx_pkt_burst() to send packets. If the return value of tx_pkt_parepare() isn't equal to the numbers of packets requested to send, warning message may be printed at the user layer. Currently, tx_pkt_prepare() is assigned to dummy function when dev_stop() is called in hns3 PMD. At this moment, if user layer continues to send packets, the warning message will always be printed. So this patch modifies the address to NULL.
