Merge branch 'bpf-xdp-fwd-sample-improvements'
Jesper Dangaard Brouer says:
====================
V3: Hopefully fixed all issues point out by Yonghong Song
V2: Addressed issues point out by Yonghong Song
- Please ACK patch 2/3 again
- Added ACKs and reviewed-by to other patches
This patchset is focused on improvements for XDP forwarding sample
named xdp_fwd, which leverage the existing FIB routing tables as
described in LPC2018[1] talk by David Ahern.
The primary motivation is to illustrate how Toke's recent work
improves usability of XDP_REDIRECT via lookups in devmap. The other
patches are to help users understand the sample.
I have more improvements to xdp_fwd, but those might requires changes
to libbpf. Thus, sending these patches first as they are isolated.
