@@ -22,6 +22,10 @@ Optional properties:
 - use-ncsi: Use the NC-SI stack instead of an MDIO PHY. Currently assumes
   rmii (100bT) but kept as a separate property in case NC-SI grows support
   for a gigabit link.
+- mac-address-increment: Increment the MAC address taken by GMA command via
+  NC-SI. Specifies a signed number to be added to the host MAC address as
+  obtained by the OEM GMA command. If not specified, 1 is used by default
+  for Broadcom and Intel network cards, 0 otherwise.
 - no-hw-checksum: Used to disable HW checksum support. Here for backward
   compatibility as the driver now should have correct defaults based on
   the SoC.
