Subject: [PATCH net-next 2/5] net: dsa: qca: Make the QCA8K hardware library available globally
The Qualcomm QCA8K Ethernet switch is already supported in the kernel, as a
DSA switch. However, the Qualcomm IPQ4019 SoC contains an internal modified
QCA8K switch that does not fit into the DSA model, since it uses an
out-of-band tagging protocol.
Move the qca8k.h header file out of the QCA8K DSA driver so that the
upcoming IPQ4019 QCA8K switchdev driver can include it.
Refactor qca8k-common into a separate module so that the IPQESS driver can
be built as a module.
