From: Mark Cave-Ayland <mark.cave-ayland@xxxxxxxxxxxx>
All of the rtlwifi drivers have an error in the routine that tests if
the received data is "special". The 16-bit quantity is big-endian, but
was being extracted in native CPU mode. One of the effects of this bug
is to inhibit association under some conditions.
A statement that would have made the code correct had been changed to
a comment. Rather than just reinstating that code, the fix here passes
sparse tests.
