Whups, yeah - so was I :) I thought for sure I had enabled -proposed
on my D05
Anyway, I was also an idiot and didn't realize I could just check our
weekly scheduled tests and see that the (correct) -proposed kernels
had both booted fine on D05, so I didn't need to do that test
manually.

  [Impact]
  The 1G NICs on the Huawei XR320 system do not detect link on initial boot, 
resulting in broken networking. This is a regression caused by:

308c6cafde01 ("net: hns: All ports can not work when insmod hns ko

  While that fixed an issue with phys after reloading the driver, it
  caused an issue with some phys on initial load.

  [Fix]
  This was addressed by upstream commit c77804be53369 ("net: hns: Fix WARNING

this issue.

  [Regression Risk]
  Restricted to the hns driver, which is only used by certain HiSilicon SOCs.

Yeah, the commit message describes a different problem than the one
you are seeing, but I suspect you were also broken by 308c6cafde01,
because that added the phy_stop() call.

It stops the underlying phy, but it should be started again when the
interface is brought up (hns_nic_net_up()). I don't know why it isn't
- perhaps another side-effect of calling phy_stop() before
phy_start(). Thanks for testing - I'll get this fix submitted.

OK, thanks. Unfortunately, there's no smoking gun there, so I've
started a bisect and uploaded another test kernel to
https://launchpad.net/~dannf/+archive/ubuntu/xr320/+packages. Can you
give that a try once it finishes building?

Could you save 'dmesg' output of the bad kernel to a file and upload
that once you reboot to working networking?

Title:
  HiSilicon HNS ethernet broken in 4.15.0-45

Status in linux package in Ubuntu:
  Incomplete
Status in linux source package in Bionic:
  Incomplete
Status in linux source package in Cosmic:
  Incomplete
Status in linux source package in Disco:
  Incomplete

Bug description:
  A number of HiSilicon patches were backported in
  https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1810457 from
  5.0rc1.

  Subsequently, I lost networking on my Huawei TaiShan XR320 boards.

  There are 6 commits to drivers/net/ethernet/hisilicon/hns between
  5.0rc1 and (current) 5.0rc8 - and I know my networking works fine with
  a 5.0rc8 mainline build.

  Can we do another update run for the next 4.15.0 kernel service
  release, to include HiSilicon changes from 5.0rc8?
