2.7.4
From: Xi Wang <[email protected]>
Because the current statistics for size 8192~12287 are only valid for GE,
the ranges of 8192~9216 and 9217~12287 are valid only for LGE/CGE, and are
always 0 for GE interfaces. it is easy to cause confusion when viewing the
packet statistics using the command ethtool -S.
This patch removes the 8192~12287 range of packet statistics and uses the
8192~9216 and 9217~12287 ranges for statistics. This change depends on the
firmware upgrade.

2.7.4
From: Yunsheng Lin <[email protected]>
There are two level of vlan tables in hardware, one is port vlan
which is shared by all functions, the other one is function
vlan table, each function has it's own function vlan table.
Currently, PF sets the port vlan table, and vf sets the function
vlan table, which will cause packet lost problem.
This patch fixes this problem by setting both vlan table, and
use hdev->vlan_table to manage thet port vlan table.

From: Huazhong Tan <[email protected]>
When phy exists, phy_addr must less than PHY_MAX_ADDR.
If not, hclge_mac_mdio_config should return error.
And for fiber(phy_addr=0xff), it does not need hclge_mac_mdio_config.

This patch fixes the handling of the check when number of vports
are detected to be more than available TPQs. Current handling causes
an out of bounds access in hclge_map_tqp().
Fixes: 7df7dad633e2 ("net: hns3: Refactor the mapping of tqp to vport")

2.7.4
From: Yunsheng Lin <[email protected]>
When mac supports DCB, but is in GE mode, it does not support
querying pfc stats, firmware returns error when trying to
query the pfc stats. this creates a lot of noise in the kernel
log when it prints the error log.
This patch fixes it by removing the error log, because it already
return the error to the user space, so the user should be aware of
the error.
