Subject: [net-next 0/7][pull request] L2 Fwd Offload & 10GbE Intel Driver Updates 2018-07-09

This patch series is meant to allow support for the L2 forward offload, aka
MACVLAN offload without the need for using ndo_select_queue.

The existing solution currently requires that we use ndo_select_queue in
the transmit path if we want to associate specific Tx queues with a given
MACVLAN interface. In order to get away from this we need to repurpose the
tc_to_txq array and XPS pointer for the MACVLAN interface and use those as
a means of accessing the queues on the lower device. As a result we cannot
offload a device that is configured as multiqueue, however it doesn't
really make sense to configure a macvlan interfaced as being multiqueue
anyway since it doesn't really have a qdisc of its own in the first place.

The big changes in this set are:
  Allow lower device to update tc_to_txq and XPS map of offloaded MACVLAN
  Disable XPS for single queue devices
  Replace accel_priv with sb_dev in ndo_select_queue
  Add sb_dev parameter to fallback function for ndo_select_queue
  Consolidated ndo_select_queue functions that appeared to be duplicates

The following are changes since commit c47078d6a33fd78d882200cdaacbcfcd63318234:
  tcp: remove redundant SOCK_DONE checks

Alexander Duyck (7):
  net-sysfs: Drop support for XPS and traffic_class on single queue
    device
  net: Add support for subordinate device traffic classes
  ixgbe: Add code to populate and use macvlan TC to Tx queue map
  net: Add support for subordinate traffic classes to netdev_pick_tx
  net: Add generic ndo_select_queue functions
  net: allow ndo_select_queue to pass netdev
  net: allow fallback function to pass netdev
