 * ============================================================================
+* Mar 15, 2002  Arnaldo C. Melo  o Use wp_sk()->num, as it isnt anymore in sock
 * Apr 25, 2000  Nenad Corbic     o Added the ability to send zero length packets.
 * Mar 13, 2000  Nenad Corbic	 o Added a tx buffer check via ioctl call.
 * Mar 06, 2000  Nenad Corbic     o Fixed the corrupt sock lcn problem.
