The packet socket manual page does not list all socket options.
This patch adds descriptions of the common packet socket options
PACKET_AUXDATA, PACKET_FANOUT, PACKET_RX_RING, PACKET_STATISTICS,
PACKET_TX_RING
and the ring-specific options
PACKET_LOSS, PACKET_RESERVE, PACKET_TIMESTAMP, PACKET_VERSION
It does not yet add descriptions for
PACKET_COPY_THRESH, PACKET_HDRLEN, PACKET_ORIGDEV,
PACKET_TX_HAS_OFF, PACKET_TX_TIMESTAMP, PACKET_VNET_HDR
It tries to balance being informative with exposing kernel detail
that is unlikely to be used by most readers or that may change
frequently. For implementation details, the manpage points to the
documentation in kernel Documentation/networking. Let me know if
options should be added or removed.
Source: PACKET_FANOUT, PACKET_RX_RING and PACKET_VERSION are in
/tools/testing/net/psock_fanout.c in the latest Linux kernel source
tree. PACKET_STATISTICS was in the first version of that test.
PACKET_TX_RING I have used elsewhere. The other options are based
on reading kernel code.

The use of "symbols" in the existing description is confusing;
it's "bytes". Other fixes as well.

It is helpful to have a short description about what the different
functions in string.h do.

Incorporate some of the existing material in the page
into the STYLE GUIDE, and add a lot more material, mainly
drawn from the "Global changes" sections in the release
changelogs.

Change "NULL pointer: to "NUL " or null pointer".
POSIX uses the term "null pointer", not "NULL pointer".
