Subject: [PATCH 26/31] net: hns3: call hns3_nic_net_open() while doing
|
|
HNAE3_UP_CLIENT
|
|
Origin: https://git.kernel.org/linus/e888402789b9db5de4fcda361331d66dbf0cd9fd
|
|
|
|
For HNAE3_DOWN_CLIENT calling hns3_nic_net_stop(), HNAE3_UP_CLIENT
|
|
should call hns3_nic_net_open(), since if the number of queue or
|
|
the map of TC has is changed before HHAE3_UP_CLIENT is called,
|
|
it will cause problem.
|
|
|
|
Also the HNS3_NIC_STATE_RESETTING flag needs to be cleared before
|
|
hns3_nic_net_open() called, and set it back while hns3_nic_net_open()
|
|
failed.
|
|
|
|
