wilc1000: Add support for enabling CRC
The driver so far has always disabled CRC protection. This means any
data corruption that occurrs during the SPI transfers could go
undetected. This patch adds module parameters enable_crc7 and
enable_crc16 to selectively turn on CRC7 (for command transfers) and
CRC16 (for data transfers), respectively.
The default configuration remains unchanged, with both CRC7 and CRC16
off.
The performance impact of CRC was measured by running ttcp -t four
times in a row on a SAMA5 device:
