From 3310c3c3d4c05c0d13f32f08f978ba4813e2a39a Mon Sep 17 00:00:00 2001 From: Kevin Benton Date: Fri, 17 Apr 2015 04:28:58 -0700 Subject: [PATCH] Remove double queries in l3 DB get methods Two frequently called functions were querying the routerport table and the corresponding ports just to get the port ID. Then they were calling get_ports again with those port IDs, resulting in two queries to the port table when there should have only been one. This eliminates the second call to get_ports since all of the necessary data hase been retrieved from the port table.
