Subject: [PATCH net-next 14/19] net: hns: delete redundancy ring enable operations
From: Daode Huang <huangdaode@...ilicon.com>
When network interface is enabled, the ring enable operation is
conducted twice. This patch deletes the redundancy code of ring enable,
and integrates hnae_ae_ops.toggle_queue_status other functions to
hns_ae_start.
