  The Qualcomm IPQ4019 includes an internal 5 ports switch, which is
connected to the CPU through the internal IPQESS Ethernet controller.

Add support for this internal interface, which is internally connected to a
modified version of the QCA8K Ethernet switch.

This Ethernet controller only support a specific internal interface mode
for connection to the switch.

Please use scripts/get_maintainers.pl to get a list of necessary people
and lists to CC.  It might happen, that command when run on an older
kernel, gives you outdated entries.  Therefore please be sure you base
your patches on recent Linux kernel.

You skipped the actual maintainers of the file.

Best regards,
Krzysztof
