Subject: [PATCH 0/3 net-next] Bring sizeof(net_device) down to < 2K bytes

The size of struct net_device crossed the 2K boundary a while ago which
is a waste in combination with many net namespaces. This series brings
the size of struct net_device down to well below 2K in total size with
a typical configuration. Some reserves a several holes leave room for
further expansion.

Thomas Graf (3):
  e1000: Allocate pm_qos_req as needed
  net_device: Reorder members to fill holes
  net_device: Add minimal padding to allow for net_device pointer
    alignment

@Jeff: I only boot tested the e1000 in a virtual machine.
