Most ULP modes in cxgbe's TOE are enabled on the fly when a protocol is needed (e.g. ULP_MODE_ISCSI is enabled by cxgbei when offloading a connection using iSCSI, and ULP_MODE_TLS is enabled when RX TLS keys are programmed for a TOE connection). The one exception to this is ULP_MODE_TCPDDP. Currently the cxgbe driver enables ULP_MODE_TCPDDP when a TOE connection is first created. However, since DDP connections cannot be converted to other connection types, this requires some special handling in the driver. For example, iSCSI daemons use the SO_NO_DDP socket option to ensure TOE connections use ULP_MODE_NONE so they can be converted to ULP_MODE_ISCSI. Similarly, using TLS receive offload (ULP_MODE_TLS) requires disabling TCP DDP for new connections by default. This commit changes cxgbe to instead switch a connection from ULP_MODE_NONE to ULP_MODE_TCPDDP when a connection first attempts to use TCP DDP via aio_read(2). This permits connections to always start as ULP_MODE_NONE and switch to a protocol-specific mode as needed.
