> 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.
