From fa0b2d1d2196dd46527a8d028797e2bca5930a92 Mon Sep 17 00:00:00 2001 From: Thomas Graf Date: Mon, 26 Mar 2007 17:38:53 -0700 Subject: [PATCH] [NET] fib_rules: Add no-operation action The use of nop rules simplifies the usage of goto rules and adds more flexibility as they allow targets to remain while the actual content of the branches can change easly.
