Here's yet another attempt tomove the XDP_QUERY_PROG{,_HW} code out
from the drivers to generic netdev code.
I took a bit different approach with the v3. In this revision I
introduced to a new netdev_xdp structure that tracks the XDP programs,
and instead of sharing the xdp_prog member between DRV and SKB (again,
they mutual exclusive). With this, there's no need for a special
"what-mode-am-I-in" flag for SKB/DRV.
Jakub, what's your thoughts on the special handling of XDP offloading?
Maybe it's just overkill? Just allocate space for the offloaded
program regardless support or not? Also, please review the
dev_xdp_support_offload() addition into the nfp code.
The last two patches move the attach flag checks to generic code, and
removes the flags member from netdev_bpf.
Please refer to the individual commit messages for more details.
The series passes test_offload.py from selftests. Thanks to Jakub for
pointing this out.
Thanks,
Björn
