Title:
  hns3: Retrieve RoCE MSI-X config from firmware

Status in linux package in Ubuntu:
  Fix Committed
Status in linux source package in Bionic:
  Fix Committed

Bug description:
  [Impact]
  MSI-X configuration is hardcoded in the hns3 driver, but the actual 
configuration may change across revisions. Query firmware for the MSI-X 
offset/numbers instead.

  [Test Case]
  Regression testing: Confirm that, on existing hardware, the same MSIs are 
allocated before and after the patch.

  grep hns /proc/interrupts  | grep MSI | cut -d: -f1 > msi.old
  grep hns /proc/interrupts  | grep MSI | cut -d: -f1 > msi.new
  diff -u msi.old msi.new

  [Fix]
  375dd5e43212 net: hns3: Refine the MSIX allocation for PF
  07acf909ee33 net: hns3: Fix MSIX allocation issue for VF

  [Regression Risk]
  Restricted to a single driver, only used on HiSilicon SoCs.
