Subject: [PATCH 24/26] 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.
