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.

I went over the man page again, and it looks good to me.
Great work and thanks for following up Willem!
Ping, Michael, any progress on this one? Lets not get this work
lost somewhere as it happened in March last year ...
Thanks,
Daniel
