Subject: [PATCH] merge raw4_opt with raw_sock

From: Arnaldo Carvalho de Melo <[email-masked]>
Date: Fri, 14 Jan 2005 20:13:25 -0200

Hi David,

	Now the raw_sock one, available at:

bk://kernel.bkbits.net/acme/connection_sock-2.6

	Later today I'll reclone and redo the SCTP and IPv6 bits,
then the connection_sock introduction.

- Arnaldo

  [RAW] merge raw_sock with raw_opt
  
  No need for two structs, follow the new inet_sock layout
  style.
