[PATCH net-next 1/2] selftests: drv-net: pace ethtool_std_stats packet generation

[Jakub Kicinski <kuba@kernel.org>]

mausezahn defaults to sending packets back to back at the maximum rate,
which can cause packet loss, especially if receiver is running a debug
kernel. Space the generated packets out (-d 10usec), like ethtool_rmon
already does.
