Bug Description

[Impact]
hns hardware supports vlan TSO but driver does not set the flag.

[Test Case]
Performance run through vlan TSO shall reach limitation.

[Fix]
0d581ba311a2 net: hns: add support for vlan TSO

[Regression Risk]
Patch restricted to hns3 driver.

"""[Bug Description]
When add vlan to the net ports, the performance is almost 50% lower than no vlan.

[Steps to Reproduce]
1.add vlan to net port(10G fibre);
2.add ip to this vlan;
3.run iperf to test the performance;

[Actual Results]
iperf result is about 5~6Gbp/s

[Expected Results]
iperf result is about 9.4Gbp/s

[Reproducibility]
Conditionally Recur

[Additional information]
Hardware: D05
Firmware: NA
Kernel: NA

[Resolution]
The hip07 chip support vlan TSO, adds NETIF_F_TSO and NETIF_F_TSO6 flags to vlan_features."""

This bug is awaiting verification that the kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-disco' to 'verification-done-disco'. If the problem still exists, change the tag 'verification-needed-disco' to 'verification-failed-disco'.

If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed.
