From ab35cd4b8f42b5e4a9338949581a510e98503b28 Mon Sep 17 00:00:00 2001 From: Eric Dumazet Date: Tue, 19 May 2009 15:16:34 -0700 Subject: sch_teql: Use net_device internal stats We can slightly reduce size of teqlN structure, not duplicating stats structure in teql_master but using stats field from net_device.stats for tx_errors and from netdev_queue for tx_bytes/tx_packets/tx_dropped values.
