From: Marc Kleine-Budde <mkl@pengutronix.de>

commit 97926d5a847ca1758ad8702ce591e3b05a701e0d upstream.

This patch fixes the parsing of the cmd line supplied start time on 32
bit systems. A "long" on 32 bit systems is only 32 bit wide and cannot
hold a timestamp in nano second resolution.

Fixes: 040806343bb4 ("selftests/net: so_txtime multi-host support")
