Subject: [PATCH net 1/2] selftests/net: so_txtime: fix parsing of start time stamp on 32 bit systems

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")
