[PATCH 1/8] wcn36xx: initialize device defaults on start

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

 



Set up default configuration for the device when we call start.
The defaults come from dumps from the prima driver for the same
hardware.

This fixes transmit A-MPDU; previously only one MPDU would be
sent per A-MPDU due to missing MAX_MPDUS_IN_AMPDU setting.
