[Bug libc/11027] New: Class Selector Codepoints not deprecated

[philipp at redfish-solutions dot com]

It was correctly pointed out (offline) that the comments in bug #10789 give the
appearance that the DSCP values have completely obsoleted all previous uses of
the IP ToS field.

That's not correct.  The CSx values (CS0..CS7) may (and often do) coexist with
the Assured Forwarding (AFxx) values.

Indeed CS1 precedes the series AF11..AF13, CS2 precedes the series AF21..AF23,
etc. and CS6 immediately succeeds EF.

Where do these names come from?

And if, as you suggest, these names are preferred over the IPTOS_PREC* names
then the latter should be defined in terms of your macros, not the other way around.

Patch for netinet/ip.h to add Class Selector definitions

This expresses IPTOS_PREC_xxx in terms of IPTOS_CLASS_yyy, and not the
converse, as Ulrich was requesting.

Uli: I've made these changes as per your request.  Can we have some movement on
this please, or are there other requirements?  Thanks.
