> 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
> and are available in the git repository at:
>   git://git.kernel.org/pub/scm/linux/kernel/git/jkirsher/next-queue 10GbE

Pulled, thanks Jeff.
