Title:
  [UBUNTU 20.04] s390x/pci: increase CONFIG_PCI_NR_FUNCTIONS to 512 in
  kernel config

Status in Ubuntu on IBM z Systems:
  Fix Committed
Status in linux package in Ubuntu:
  Fix Committed

Bug description:
  The current CONFIG_PCI_NR_FUNCTIONS setting (64) is not sufficient
  anymore for network adapters that support SRIOV and up to 130 PCI
  functions.

  Therefore we need to increase the CONFIG_PCI_NR_FUNCTIONS value to 512,
  within the kernel config for Ubuntu 20.04
