To: kvalo; +Cc: linux-kernel, prameela.garnepudi, Prameela Rani Garnepudi
The file rsi_91x_hal.c will contain new firmware loading method for
RSI 9113 chipset. So this file will have device specific operations.
As the file 'rsi_91x_pkt.c' contains code for preparing device
(frimware understandable) specific descriptors for the transmit frames,
it is moved to 'rsi_91x_hal.c'

If you send a new version of the patchset mark it as "[PATCH v2]". Also
I don't see a changelog anywhere, what has changed since the version you
posted last December?
Please read:

The file rsi_91x_hal.c will contain new firmware loading method for
RSI 9113 chipset. So this file will have device specific operations.
As the file 'rsi_91x_pkt.c' contains code for preparing device
(frimware understandable) specific descriptors for the transmit frames,
it is moved to 'rsi_91x_hal.c'
