From 0c838ff1ade71162775afffd9e5c6478a60bdca6 Mon Sep 17 00:00:00 2001 From: "David S. Miller" Date: Mon, 31 Jan 2011 16:16:50 -0800 Subject: ipv4: Consolidate all default route selection implementations. Both fib_trie and fib_hash have a local implementation of fib_table_select_default(). This is completely unnecessary code duplication. Since we now remember the fib_table and the head of the fib alias list of the default route, we can implement one single generic version of this routine. Looking at the fib_hash implementation you may get the impression that it's possible for there to be multiple top-level routes in the table for the default route. The truth is, it isn't, the insert code will only allow one entry to exist in the zero prefix hash table, because all keys evaluate to zero and all keys in a hash table must be unique.
