-@Note: This interface is implemented to operate in zero-copy mode only:
-        - Rx buffers are allocated statically and passed directly to the LwIP stack,
-          they will return back to ETH DMA after been processed by the stack.
-        - Tx Buffers will be allocated from LwIP stack memory heap,
-          then passed to ETH HAL driver.
-
-@Notes:
-  1.a. ETH DMA Rx descriptors must be contiguous, the default count is 4,
-       to customize it please redefine ETH_RX_DESC_CNT in stm32xxxx_hal_conf.h
-  1.b. ETH DMA Tx descriptors must be contiguous, the default count is 4,
-       to customize it please redefine ETH_TX_DESC_CNT in stm32xxxx_hal_conf.h
-
-  2.a. Rx Buffers number must be between ETH_RX_DESC_CNT and 2*ETH_RX_DESC_CNT
-  2.b. Rx Buffers must have the same size: ETH_RX_BUFFER_SIZE, this value must
-       passed to ETH DMA in the init field (EthHandle.Init.RxBuffLen)
-  2.c  The RX Ruffers addresses and sizes must be properly defined to be aligned
-       to L1-CACHE line size (32 bytes).

-/**
- * \defgroup psock Protosockets library
- * @{
- *
- * The protosocket library provides an interface to the uIP stack that is
- * similar to the traditional BSD socket interface. Unlike programs
- * written for the ordinary uIP event-driven interface, programs
- * written with the protosocket library are executed in a sequential
- * fashion and does not have to be implemented as explicit state
- * machines.
- *
- * Protosockets only work with TCP connections.
- *
- * The protosocket library uses \ref pt protothreads to provide
- * sequential control flow. This makes the protosockets lightweight in
- * terms of memory, but also means that protosockets inherits the
- * functional limitations of protothreads. Each protosocket lives only
- * within a single function. Automatic variables (stack variables) are
- * not retained across a protosocket library function call.
- *
- * \note Because the protosocket library uses protothreads, local
- * variables will not always be saved across a call to a protosocket
- * library function. It is therefore advised that local variables are
- * used with extreme care.
- *
- * The protosocket library provides functions for sending data without
- * having to deal with retransmissions and acknowledgements, as well
- * as functions for reading data without having to deal with data
- * being split across more than one TCP segment.
- *
- * Because each protosocket runs as a protothread, the protosocket has to be
- * started with a call to PSOCK_BEGIN() at the start of the function
- * in which the protosocket is used. Similarly, the protosocket protothread can
- * be terminated by a call to PSOCK_EXIT().

- * uIP is a small implementation of the IP, UDP and TCP protocols (as
- * well as some basic ICMP stuff). The implementation couples the IP,
- * UDP, TCP and the application layers very tightly. To keep the size
- * of the compiled code down, this code frequently uses the goto
- * statement. While it would be possible to break the uip_process()
- * function into many smaller functions, this would increase the code
- * size because of the overhead of parameter passing and the fact that
- * the optimier would not be as efficient.
- *
- * The principle is that we have a small buffer, called the uip_buf,
- * in which the device driver puts an incoming packet. The TCP/IP
- * stack parses the headers in the packet, and calls the
- * application. If the remote host has sent data to the application,
- * this data is present in the uip_buf and the application read the
- * data from there. It is up to the application to put this data into
- * a byte stream if needed. The application will not be fed with data
- * that is out of sequence.
- *
- * If the application whishes to send data to the peer, it should put
- * its data into the uip_buf. The uip_appdata pointer points to the
- * first available byte. The TCP/IP stack will calculate the
- * checksums, and fill in the necessary header fields and finally send
- * the packet back to the peer.
