Subject: [PATCH net-next 5/6] selftests: mptcp: turn rp_filter off on each NIC
Date: Tue, 22 Jun 2021 12:25:22 -0700	[thread overview]
Message-ID: <20210622192523.90117-6-mathew.j.martineau@linux.intel.com> (raw)
In-Reply-To: <20210622192523.90117-1-mathew.j.martineau@linux.intel.com>

From: Yonglong Li <liyonglong@chinatelecom.cn>

To turn rp_filter off we should:

  echo 0 > /proc/sys/net/ipv4/conf/default/rp_filter

and

  echo 0 > /proc/sys/net/ipv4/conf/all/rp_filter

before NIC created.
