Subject: sch_teql: Use net_device internal stats
X-Git-Tag: v2.6.31-rc1~330^2~354
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=ab35cd4b8f42;p=karo-tx-linux.git

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.
