samples/bpf: Fix tc and ip paths in xdp2skb_meta.sh

2018-08-24T11:07:06+00:00

[ Upstream commit b9626f45abccd044f8048269c67720f0719f2d4e ] The below path error can occur: # ./xdp2skb_meta.sh --dev eth0 --list ./xdp2skb_meta.sh: line 61: /usr/sbin/tc: No such file or directory So just use command names instead of absolute paths of tc and ip. In addition, it allow callers to redefine $TC and $IP paths Fixes: 36e04a2d78d9 ("samples/bpf: xdp2skb_meta shows transferring info from XDP to SKB") Reviewed-by: Jesper Dangaard Brouer Signed-off-by: Taeung Song Acked-by: Jesper Dangaard Brouer Signed-off-by: Daniel Borkmann Signed-off-by: Sasha Levin Signed-off-by: Greg Kroah-Hartman
