* card is being used for dpmac 3-4. (X-M12-XFI could also have been used)

|
* And also that this card is connected to IO Slot 1 (could have been connected
|
|
|
|
* to any of the 8 IO slots (IO slot 1 - IO slot 8)).
|
|
|
|
* similarly, it is also being assumed that MDIO 1 is selected on X-M7-40G card
|
|
|
|
* used in serdes1 protocol 19 (could have selected MDIO 2)
|
|
|
|
* To override these settings "dpmac" environment variable can be used after
|
|
|
|
* defining "dpmac_override" in hwconfig environment variable.
|
|
|
|
* This table has limited serdes protocol entries. It can be expanded as per
|
|
|
|
* requirement.
