Merge branch 'bpf-nfp-programmable-rss'

Jakub Kicinski says:

====================
This small series adds a feature which extends BPF offload beyond
a pure host processing offload and firmly into the realm of
heterogeneous processing.  Allowing offloaded XDP programs to set
the RX queue index opens the door for defining fully programmable
RSS/n-tuple filter replacement.  In fact the device datapath will
skip the RSS processing completely if BPF decided on the queue
already, making the XDP program replace part of the standard NIC
datapath.

We hope some day the entire NIC datapath will be defined by BPF :)
