From: Rafał Miłecki <[email protected]> Driver's main init/attach function brcmf_attach() was handling both: wiphy allocation and driver initialization. It meant getting a new wiphy on every init (initial, resume, error recovery).
For supplicants/authenticators and Linux users it's move convenient to have the same wiphy over driver's lifetime. It allows e.g. automatic recovery after a firmware crash. This patchset was tested on BCM4366 (PCIe) and BCM43430 (SDIO). Right now only PCIe makes use of keeping the same wiphy. I got RPi Zero W so I'm planning to add firmware crash recovery & keep wiphy for SDIO in the future.
