-Subject: [PATCH] ath10k: support bus and device specific API 1 BDF selection
-
-Some ath10k IPQ40xx devices like the MikroTik hAP ac2 and ac3 require the
-BDF-s to be extracted from the device storage instead of shipping packaged
-API 2 BDF-s.
-
-This is required as MikroTik has started shipping boards that require BDF-s
-to be updated, as otherwise their WLAN performance really suffers.
-This is however impossible as the devices that require this are release
-under the same revision and its not possible to differentiate them from
-devices using the older BDF-s.
-
-In OpenWrt we are extracting the calibration data during runtime and we are
-able to extract the BDF-s in the same manner, however we cannot package the
-BDF-s to API 2 format on the fly and can only use API 1 to provide BDF-s on
-the fly.
-This is an issue as the ath10k driver explicitly looks only for the
-board.bin file and not for something like board-bus-device.bin like it does
-for pre-cal data.
-Due to this we have no way of providing correct BDF-s on the fly, so lets
-extend the ath10k driver to first look for BDF-s in the
-board-bus-device.bin format, for example: board-ahb-a800000.wifi.bin
-If that fails, look for the default board file name as defined previously.
