Subject: [PATCH net-next v2 0/5] amd-xgbe: add support for AMD Crater

Add support for a new AMD Ethernet device called "Crater". It has a new
PCI ID, add this to the current list of supported devices in the
amd-xgbe devices. Also, the BAR1 addresses cannot be used to access the
PCS registers on Crater platform, use the indirect addressing via SMN
instead.

Changes since v1:
- PCI config accesses can race with other drivers performing SMN accesses
  so, fall back to AMD SMN API to avoid race.
- add the xgbe_ prefix to new functions

Raju Rangoju (5):
  amd-xgbe: reorganize the code of XPCS access
  amd-xgbe: reorganize the xgbe_pci_probe() code path
  amd-xgbe: add support for new XPCS routines
  amd-xgbe: Add XGBE_XPCS_ACCESS_V3 support to xgbe_pci_probe()
  amd-xgbe: add support for new pci device id 0x1641
