This patch fixes the bug that hardware configuration called
tc_size doesn't restore to the initial value when starting
the app, configuring PFC and then restarting the app,
because of the tc_mode didn't initial when rss is disabled.

From: "Wei Hu (Xavier)" <xavier_huwei@163.com>

When the application using VF device exits abnormally, for example,
when it is killed by 'kill -9', kernel PF netdev driver also stores
the corresponding configuration table entries of VF device.

This patch fixes it by adding message of deleting VF configuration
table entry corresponds to the revision of kernel hns3 netdev
driver, the new message is added to notify the kernel PF netdev
driver to clean up the VF configuration initialization during VF
initialization.

This revision is compatible with the old version of kernel hns3
netdev driver. The old version of kernel pf netdev driver will
ignore this message.

Ethernet minimum packet length is 64 bytes. If upper application
sends packets with less than 60 bytes in length(no CRC), driver
adds padding processing to avoid failure.

From: Chengchang Tang <tangchengchang@hisilicon.com>

This patch removes the macro 'HNS3_REG_MSG_DATA_OFFSET' which is used to
prevent the array from accessing violation and it limits the response data
length to be 4. but the limit value is too short to get some longer
information such as 6 byte MAC address.

This patch modify the length of response data from mailbox to allows the
response data length to be 8. So that the VF driver could get more data
from PF drvier by mailbox.

From: Huisong Li <lihuisong@huawei.com>

Currently, port link status is "up" in VF driver after user calling the
rte_eth_dev_stop API. This is unreasonable.

Therefore, this patch adjusts the strategy of getting link status from
PF driver for VF. VF drvier should stop getting link status from PF by
canceling the alarm that VF driver send mailbox message to PF driver,
when the rte_eth_dev_stop API is called. And VF driver should restore
the alarm when the rte_eth_dev_start API is called.

When setting duplicate vlan, hns3 driver will also add vlan entry
to vlan linked list, and this is unreasonable.

This patch adds checking whether the VLAN to be added already exists
in the linked list and preventing adding duplicate vlan.

From: Hao Chen <chenhao164@huawei.com>

This patch fixes the bug that hardware configuration called
tc_size doesn't restore to the initial value when starting
the app, configuring PFC and then restarting the app,
because of the tc_mode didn't initial when rss is disabled.

Fixes: c37ca66f2b27 ("net/hns3: support RSS")
