Date: Mon,  9 May 2022 15:21:47 -0700	[thread overview]
Message-ID: <20220509222149.1763877-12-eric.dumazet@gmail.com> (raw)
In-Reply-To: <20220509222149.1763877-1-eric.dumazet@gmail.com>

From: Eric Dumazet <edumazet@google.com>

Set the TSO driver limit to GSO_MAX_SIZE (512 KB).

This allows the admin/user to set a GSO limit up to this value.

ip link set dev veth10 gso_max_size 200000
