Subject: [PATCH v4 net-next 0/2] 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 v3:
- Club patches 2 and 3 to avoid bisect issues.
- Modified license in xgbe-smn.h to match the license in all the other files.
- Modified the function get_pcs_index_and_offset() to reflect the name.

Raju Rangoju (2):
  amd-xgbe: reorganize the code of XPCS access
  amd-xgbe: add support for Crater ethernet device
