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.
