NetCP 1.5 available on newer K2 SoCs such as K2E and K2L introduced 3 variants of the ethss subsystem, 9 port, 5 port and 2 port. These have one host port towards the CPU and N external slave ports. To customize the driver for these new ethss sub systems, multiple compatibility strings are introduced. Currently some of parameters that are different on different variants such as number of ALE ports, stats modules and number of ports are defined through constants. These are now changed to variables in gbe_priv data that get set based on the compatibility string. This is required as there are no hardware identification registers available to distinguish among the variants of NetCP 1.5 ethss. However there is identification register available to differentiate between NetCP 1.4 vs NetCP 1.5 and the same is made use of in the code to differentiate them.
