Subject: [PATCH v3 18/22] wifi: nxpwifi: add core files
Nxpwifi is a two modules driver: one for core layer and
another one is for bus driver.
Core layer supports needed functions to allow bus driver
to create an working instance for the bus driver.
Struct nxpwifi_if_ops is defined to allow bus driver to hook
callback functions to core layer for the operations of bus
related functions.
