Merge branch '10GbE' of git://git.kernel.org/pub/scm/linux/kernel/git/jkirsher/next-queue
Jeff Kirsher says:
====================
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
