This change enable support for the QCA headers in QCA83337 driver.
A 2 bytes header will be added by the switch on every incoming packet
to identify the ingress port, and the DSA tagging code will add a
similar 2 bytes header to control which port is used to send a
particular packet.

QCA tags are used on QCA ar8xxx switch family. This change adds support
for encap/decap using 2 bytes header mode.

This patch contains initial init & registration code for QCA8337. It
will detect a QCA8337 switch, if present and declared in DT/platform.
Each port will be represented through a standalone net_device interface,
as for other DSA switches. CPU can communicate with any of the ports by
setting an IP@
MIB counters can now be reported through each switch port by using
"ethtool -S".

This patch is adding support for port6 specific options to device tree.
They can be used to setup the second xMII interface, and connect it to
one of the switch port.

ethtool has a register dump command, which should already be supported
by the current code in net/dsa/slave

Normally the program attachment place (like sockets, qdiscs) takes
care of rcu protection and calls bpf_prog_put() after a grace period.
The programs stored inside prog_array may not be attached anywhere,
so prog_array needs to take care of preserving rcu protection.
Otherwise bpf_tail_call() will

About rx zerocopy, I have a question:
