And what would you think responds to the pings other than the CPU?

Just did a quick google to see what chipset and if a single chip is used for all the functions but didn't find anything enlightening, except for a possibly too simple to be true way of bypassing the shubs security.

The chipset and configuration of the SH has been discussed here previously.
The cable modem components are integrated in the main CPU. The LAN ports are handled by a dedicated switch chip.

If ping replies are not dealt with by the chips own routines and is affected by firmware, that could be another avenue.

Ping replies are dealt with by the OS kernel.

Well there is... There's packets that get through partly and are corrected by ECC and there's packets that do not get through on first attempt and are retried.

Don't even go there. You don't want to try it.
