---help---
To maximize throughput, an endpoint can be configured for ping-pong
operation. When this is done the input and output endpoint with the same
address are used in the same direction. The CPU or DMA Controller can
then read/write one data buffer while the USB module writes/reads from
the other buffer. This gives double buffered communication.

* Name: pkt_recvfrom

* Description:
* Implements the socket recvfrom interface for the case of the AF_INET

* is connection-oriented.
*
* If 'from' is not NULL, and the underlying protocol provides the source
* address, this source address is filled in. The argument 'fromlen' is
* initialized to the size of the buffer associated with from, and
* modified on return to indicate the actual size of the address stored
* there.
*
* Parameters:
* psock A pointer to a NuttX-specific, internal socket structure
* buf Buffer to receive data
* len Length of buffer
* flags Receive flags
* from Address of source (may be NULL)
* fromlen The length of the address structure
*
* Returned Value:
* On success, returns the number of characters received. If no data is
* available to be received and the peer has performed an orderly shutdown,
* recv() will return 0. Otherwise, on errors, a negated errno value is
* returned (see recvfrom() for the list of appropriate error values).

* determined by the address space of the socket 'psock'.
*
* If the socket 'psock' is of type SOCK_DGRAM then 'addr' is the address
* to which datagrams are sent by default, and the only address from which
* datagrams are received. If the socket is of type SOCK_STREAM or
* SOCK_SEQPACKET, this call attempts to make a connection to the socket
* that is bound to the address specified by 'addr'.
*
* Generally, connection-based protocol sockets may successfully
* inet_connect() only once; connectionless protocol sockets may use
* inet_connect() multiple times to change their association.
* Connectionless sockets may dissolve the association by connecting to
* an address with the sa_family member of sockaddr set to AF_UNSPEC.
*
* Parameters:
* psock Pointer to a socket structure initialized by psock_socket()
* addr Server address (form depends on type of socket)
* addrlen Length of actual 'addr'

* is connection-oriented.
