[PATCH] rt2x00: Fix rt2800lib RF chip programming selection.

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Mirror the legacy Ralink driver with respect to rt2800 RF register programming. Execute
rt2800_config_channel_rt3x for all RF2020, RF3020, RF3021 & RF3022 chipsets when operating on RT3070
devices.
