Subject: [PATCH net-next 12/12] net: hns3: add HNAE3_RESTORE_CLIENT interface in enet module
From: Yunsheng Lin <linyunsheng@...wei.com>
The HNAE3_INIT_CLIENT interface is also used when changing tc
configuration, vlan/mac hardware table does not need to be restored
when tc configuration changes.
This patch adds a HNAE3_RESTORE_CLIENT interface to restore the
vlan/mac hardware table when resetting.
