From d6a4e26afb80c049e7f94e1b7b506dcda61eee88 Mon Sep 17 00:00:00 2001 From: Eric Dumazet Date: Tue, 26 May 2015 08:55:28 -0700 Subject: tcp: tcp_tso_autosize() minimum is one packet By making sure sk->sk_gso_max_segs minimal value is one, and sysctl_tcp_min_tso_segs minimal value is one as well, tcp_tso_autosize() will return a non zero value. We can then revert 843925f33fcc293d80acf2c5c8a78adf3344d49b ("tcp: Do not apply TSO segment limit to non-TSO packets") and save few cpu cycles in fast path.
