Subject: [PATCH] configure: Don't fail on missing bpftool
|
||||||
|

||||||
|

|
||||||
|
Instead of bailing out of configure if bpftool is not found, just disable
|
||||||
|
compilation of the tools that require it (i.e., xdp-bench, xdp-monitor and
|
||||||
|
xdp-trafficgen which use BPF skeletons).
