Version information: 20140812_rtl8192EU_linux_v4.3.1.1_11320 2014-08-12 version 4.3.1.1_11320 Source: ftp://files.dlink.com.au/products/DWA-131/REV_E/Drivers/DWA-131_Linux_driver_v4.3.1.1.zip This version does not currently work on newer kernels, but it does contain USB ID 2001:3319, which a lot of other repos in GitHub does not.

/*
|
|
* linux/byteorder_generic.h
|
|
* Generic Byte-reordering support
|
|
*
|
|
* Francois-Rene Rideau <fare@tunes.org> 19970707
|
|
* gathered all the good ideas from all asm-foo/byteorder.h into one file,
|
|
* cleaned them up.
|
|
* I hope it is compliant with non-GCC compilers.
|
|
* I decided to put __BYTEORDER_HAS_U64__ in byteorder.h,
|
|
* because I wasn't sure it would be ok to put it in types.h
|
|
* Upgraded it to 2.1.43
|
|
* Francois-Rene Rideau <fare@tunes.org> 19971012
|
|
* Upgraded it to 2.1.57
|
|
* to please Linus T., replaced huge #ifdef's between little/big endian
|
|
* by nestedly #include'd files.
|
|
* Francois-Rene Rideau <fare@tunes.org> 19971205
|
|
* Made it to 2.1.71; now a facelift:
|
|
* Put files under include/linux/byteorder/
|
|
* Split swab from generic support.
|
|
*
|
|
* TODO:
|
|
* = Regular kernel maintainers could also replace all these manual
|
|
* byteswap macros that remain, disseminated among drivers,
|
|
* after some grep or the sources...
|
|
* = Linus might want to rename all these macros and files to fit his taste,
|
|
* to fit his personal naming scheme.
|
|
* = it seems that a few drivers would also appreciate
|
|
* nybble swapping support...
|
|
* = every architecture could add their byteswap macro in asm/byteorder.h
|
|
* see how some architectures already do (i386, alpha, ppc, etc)
|
|
* = cpu_to_beXX and beXX_to_cpu might some day need to be well
|
|
* distinguished throughout the kernel. This is not the case currently,
|
|
* since little endian, big endian, and pdp endian machines needn't it.
|
|
* But this might be the case for, say, a port of Linux to 20/21 bit
|
|
* architectures (and F21 Linux addict around?).

|
|
|

/*
|
|
* The following macros are to be defined by <asm/byteorder.h>:
|
|
*
|
|
* Conversion of long and short int between network and host format
|
|
* ntohl(__u32 x)
|
|
* ntohs(__u16 x)
|
|
* htonl(__u32 x)
|
|
* htons(__u16 x)
|
|
* It seems that some programs (which? where? or perhaps a standard? POSIX?)
|
|
* might like the above to be functions, not macros (why?).
|
|
* if that's true, then detect them, and take measures.
|
|
* Anyway, the measure is: define only ___ntohl as a macro instead,
|
|
* and in a separate file, have
|
|
* unsigned long inline ntohl(x){return ___ntohl(x);}
|
|
*
|
|
* The same for constant arguments
|
|
* __constant_ntohl(__u32 x)
|
|
* __constant_ntohs(__u16 x)
|
|
* __constant_htonl(__u32 x)
|
|
* __constant_htons(__u16 x)
|
|
*
|
|
* Conversion of XX-bit integers (16- 32- or 64-)
|
|
* between native CPU format and little/big endian format
|
|
* 64-bit stuff only defined for proper architectures
|
|
* cpu_to_[bl]eXX(__uXX x)
|
|
* [bl]eXX_to_cpu(__uXX x)
|
|
*
|
|
* The same, but takes a pointer to the value to convert
|
|
* cpu_to_[bl]eXXp(__uXX x)
|
|
* [bl]eXX_to_cpup(__uXX x)
|
|
*
|
|
* The same, but change in situ
|
|
* cpu_to_[bl]eXXs(__uXX x)
|
|
* [bl]eXX_to_cpus(__uXX x)
|
|
*
|
|
* See asm-foo/byteorder.h for examples of how to provide
|
|
* architecture-optimized versions
