+ description:
+ The MAC address can optionally be increased (or decreased using
+ negative values) from the original value read (from a nvmem cell
+ for example). This can be used if the mac is read from a dedicated
+ partition and must be increased based on the number of device
+ present in the system. The increment will not overflow/underflow to
+ the other bytes if it's over 255 or 0.

description:
Two new bindings are now supported by the of_net driver to increase (or decrease) a mac-address. This can be very useful in case where the system extract the mac-address for the device from a dedicated partition and have a generic mac-address that needs to be incremented based on the device number. - mac-address-increment-byte is used to tell what byte must be incremented (if not set the last byte is increased) - mac-address-increment is used to tell how much to increment of the extracted mac-address decided byte.
