heh. Fastest way to change the observed speed of the internet I've yet seen.
---------- Forwarded message --------- From: <[email protected]> Date: Fri, Jul 8, 2022 at 8:51 AM Subject: [PATCH net] pktgen: Fix the inaccurate bps calculation To: <[email protected]>, <[email protected]>, <[email protected]>, <[email protected]>, <[email protected]> Cc: <[email protected]>, Gao Feng <[email protected]> From: Gao Feng <[email protected]> The prior codes use 1000000 as divisor to convert to the Mbps. But it isn't accurate, because the NIC uses 1024*1024 from bps to Mbps. The result of the codes is 1.05 times as the real value, even it may cause the result is more than the nic's physical rate.
