Sure, I just moved your pgrep check into function (it's in the same commit):
make_background_tcp_traffic()
{
	pgrep -x netstress > /dev/null && return

	local port=$(tst_get_unused_port ipv${ipver} stream)
	local ip="${1:-$(tst_ipaddr)}"

	netstress -R 3 -g $port > /dev/null 2>&1 &
	tst_rhost_run -s -c "netstress -l -H $ip -g $port"
}


Kind regards,
Petr
