Subject: [PATCH] samples/bpf: Fix tc and ip path in xdp2skb_meta.sh
Date:   Tue, 10 Jul 2018 00:04:18 +0900
Message-Id: <20180709150418.32034-1-treeze.taeung@gmail.com>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

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

  # which tc
  /sbin/tc

So use 'which' command instead of absolute path of tc and ip

Fixes: 36e04a2d78d9 ("samples/bpf: xdp2skb_meta shows transferring info from XDP to SKB")
