Correct, this is only TX.  Since it sounds likely some hardware might
only be able to offload TX, we decided to configure TX and RX
separately.  Using the OpenSSL patches, it should be transparent to
users even if only one side is offloaded.

The software RX patches exist but haven't been polished up yet.
