From 2e59af3dcbdf11635c03f22bfc9706744465d589 Mon Sep 17 00:00:00 2001 From: Eric Dumazet Date: Wed, 2 Sep 2009 18:03:00 -0700 Subject: vlan: multiqueue vlan device vlan devices are currently not multi-queue capable. We can do that with a new rtnl_link_ops method, get_tx_queues(), called from rtnl_create_link() This new method gets num_tx_queues/real_num_tx_queues from real device. register_vlan_device() is also handled.
