Subject: [PATCH 1/3] rsi: Rename the file rsi_91x_pkt.c to rsi_91x_hal.c
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'
Signed-off-by: Prameela Rani Garnepudi <prameela.j04cs@...il.com>
