Synopsis: A new protocol family, PF_IPOPTION, to handle IP options at socket interface

State-Changed-From-To: suspended->closed
State-Changed-By: bms
State-Changed-When: Mon Mar 26 14:36:38 UTC 2007
State-Changed-Why: 
It is unlikely this code will ever be committed.

Reasons:
1) This information can be obtained via cmsg so as to lie out-of-band
   of protocol data
2) This code is IPv4 specific
3) Most consumers of IP options and router alerts either live in the kernel,
   or have this information delivered via raw sockets.
