Subject: tools: bpftool: don't pass FEATURES_DUMP to libbpf
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=dc989d2ce2c2bc4b5cdc92a9d2c8a5c857448475;p=openwrt%2Fstaging%2Fblogic.git

tools: bpftool: don't pass FEATURES_DUMP to libbpf

bpftool does not export features it probed for, i.e.
FEATURE_DUMP_EXPORT is always empty, so don't try to communicate
the features to libbpf.  It has no effect.
