2.7.4
From: Jian Shen <[email protected]>
Currently hclgevf_update_port_base_vlan_info() may be called when
VF is resetting, which may cause hns3_nic_net_open() being called
twice unexpectedly.
So fix it by adding a reset check for it, and extend critical
region for rntl_lock in hclgevf_update_port_base_vlan_info().

2.7.4
From: Yunsheng Lin <[email protected]>
The linear and frag data part may be changed when the skb is expanded
or lineared in skb_cow_head() or skb_checksum_help(), which is called
by hns3_fill_skb_desc(), so the linear len return by skb_headlen()
before the calling of hns3_fill_skb_desc() is unreliable.
Move hns3_fill_skb_desc() before the calling of skb_headlen() to fix
this bug.

When device is resetting or reset failed, firmware is unable to
handle mailbox. VLAN should not be configured in this case.

2.7.4
From: Yonglong Liu <[email protected]>
When the queue depth and queue parameters are modified, there is
a low probability that TX timeout occurs. The two operations cause
the link to be down or up when the watchdog is still working. All
queues are stopped when the link is down. After the carrier is on,
all queues are woken up. If the watchdog detects the link between
the carrier on and wakeup queues, a false TX timeout occurs.
So fix this issue by modifying the sequence of carrier on and queue
wakeup, which is symmetrical to the link down action.
