Subject: [RFC PATCH v2 45/45] selftests: mptcp: random ethtool tweaking
Date: Wed,  2 Oct 2019 16:36:55 -0700	[thread overview]
Message-ID: <20191002233655.24323-46-mathew.j.martineau@linux.intel.com> (raw)
In-Reply-To: <20191002233655.24323-1-mathew.j.martineau@linux.intel.com>

From: Florian Westphal <fw@strlen.de>

Instead of unconditionally disabling TSO in ns3, turn off any of
gso/tso/gro in ns3 and/or ns4.

This gets us various combinations of GRO/GSO/TSO without a large
impact on test time.
