Daniel has brought to my attention the fact that qede is the only driver that currently supports XDP but still fails any program where xdp_adjust_head is set on the bpf_prog. This series is meant to remedy this and align qede with the rest of the driver, making it possible to remove said field.
Patch #1 contains a minor cache-saving optimization for latter patches. Patches #2 & #3 address existing issues with the qede implementation [#2 should have been a part of this as it addresses something that's affected by the additional headroom; #3 is simply here for the ride]. Patches #4 & #5 add the necessary logic in driver for ingress headroom, the first adding the infrastrucutre needed for supporting the headroon [as currently qede doesn't support such], and the second removing the existing XDP limitation. Dave, Please consider applying this to `net-next'.
