Summary: incomplete support for AF_PACKET in socketmodule.c

Initial Comment:
A comment in the source documents the AF_PACKET address
format:
- an AF_PACKET socket address is a tuple containing a
string
  specifying the ethernet interface and an integer
specifying
  the Ethernet protocol number to be received. For example:
  ("eth0",0x1234).  Optional 3rd,4th,5th elements in
the tuple
  specify packet-type and ha-type/addr -- these are
ignored by
  networking code, but accepted since they are returned
by the
  getsockname() method.

The part that says "these are ignored by networking
code," is clearly innacurate when comparing with the
packet(7) man page:
    "(...)Packets sent  through a  SOCK_DGRAM  packet
socket get a suitable physical layer header based on
the information in the sockaddr_ll destination address
 before  they are queued.(...)"

Attached patch copies the passed in addr into the
sockaddr structure.  It is against Python 2.3.4.
