The bug was traced to commit
203e4615ee9d9fa8d3506b9d0ef30095e4d5bc90
staging: vt6656: removed custom definitions of Ethernet packet types

In that patch, definitions in include/linux/if_ether.h replaced ones
in tether.h which had both big and little endian definitions.

include/linux/if_ether.h only refers to big endian values, cpu_to_be16
should be used for the correct endian architectures.

There have been reports about not being able to use access-points on channel 12 and 13 or having connectivity issues when these channels were part of the selected regulatory domain. Upon switching to these channels the brcmsmac driver suspends the transmit dma fifos. This patch resumes them upon handing over the first received beacon to mac80211.

Client data was assigned to iio_dev structure in probe but in
