[Test Case] While traffic is in-progress, use ethtool to change link speed/duplex. [Fix] Fixes have been applied upstream: 455c4401fe7a5 net: hns: add netif_carrier_off before change speed and duplex 31fabbee8f5c6 net: hns: add the code for cleaning pkt in chip [Regression Risk] The only Ubuntu-supported system that uses this driver is the HiSilicon D05 board, on which the fix was explicitly tested.
