herwise it should be returning error and no virtual irq will be allocated.
As per your return value it seems the device node is not getting
registered, perhaps the entry is
missing in DTS file. Try with just ioremap and see if virtual irq is
returned properly.

you should start the

Take a step forward and do some hands on. If any problem occurs then
post for specific help,
as porting itself is a big task and dosent have really straight forward steps.
Good Luck

hy the total bandwidth
should limit to less than 100 Mbps? At least 400Mbps should be expected, please
correct if I am wrong!

is all of the 4 ports should support 100Mbps

Then why bandwidth gets reduced when more than one port are

Any reason or suggestion I should check for this problem?
