Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net
Lots of overlapping changes. Also on the net-next side the XDP state management is handled more in the generic layers so undo the 'net' nfp fix which isn't applicable in net-next. Include a necessary change by Jakub Kicinski, with log message: ==================== cls_bpf no longer takes care of offload tracking. Make sure netdevsim performs necessary checks. This fixes a warning caused by TC trying to remove a filter it has not added. Signed-off-by: Jakub Kicinski <jakub.kicinski@netronome.com> Reviewed-by: Quentin Monnet <quentin.monnet@netronome.com> ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
