netdev: introduce new NETIF_F_HW_SWITCH_OFFLOAD feature flag for switch device offloads
This is a high level feature flag for all switch asic offloads
switch drivers set this flag on switch ports. Logical devices like
bridge, bonds, vxlans can inherit this flag from their slaves/ports.
The patch also adds the flag to NETIF_F_ONE_FOR_ALL, so that it gets
propagated to the upperdevices (bridges and bonds).
