+ [DECNet] fib: Fix out of bound access of dn_fib_props[]
+
+ Backported from 2.6. Found and fixed from Thomas Graf :
+
+ Fixes a typo which caused fib_props[] to have the wrong size
+ and makes sure the value used to index the array which is
+ provided by userspace via netlink is checked to avoid out of
+ bound access.
