Packet Socket API may reject SendTo service for TCP socket unexpectedly

When the firmware was configured via taglist to support more than 4 DPM packet services for Socket API, the firmware might reject a SendTo request for a TCP socket with status code ERR_HIL_OUTOFMEMORY or ERR_SOCK_SOULDBLOCK. The data is not sent to the communication peer. This happens when more than 4 SendTo services are active on the same socket and not yet confirmed by the firmware.

Workaround: Make sure that the application does not request more than 4 SentTo services in parallel for the same socket. There should be no more than 4 pending, unconfirmed SendTo services per TCP socket.
