commit a497e47d4aec37aaf8f13509f3ef3d1f6a717d88 upstream.

If we do a zero size allocation then it will oops.  Also we can't be
sure the user passes us a NUL terminated string so I've added a
terminator.

This code can only be triggered by root.

All of the rtlwifi drivers have an error in the routine that tests if the data is "special". If it is, the subsequant transmission will be at the lowest rate to enhance reliability. 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 as the TX rate is too high. Based on suggestions by Joe Perches, the entire routine is rewritten. One of the local headers contained duplicates of some of the ETH_P_XXX definitions. These are deleted.
