Title:
net: hns: Avoid hang when link is changed while handling packets
Status in linux package in Ubuntu:
Incomplete
Bug description:
[Impact]
If an admin uses ethtool to change the link speed or duplex setting while the
hardware is still processing packets, a hardware hang may result.
[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.
