SUSE Linux Enterprise Server 12 Service Pack 1 (SLES 12 SP1)
On a running system, one can use either
echo 32 >/proc/sys/net/ipv4/tcp_min_tso_segsor
sysctl -w net.ipv4.tcp_min_tso_segs=32
To make the change permanent, either add line "net.ipv4.tcp_min_tso_segs = 32" to /etc/sysctl.conf, or the preferred solution is to create a new file with ".conf" extension containing "net.ipv4.tcp_min_tso_segs = 32" and put it in /etc/sysctl.d.
