 * Processing routines for buffers arranged in the DHCP/BOOTP option format
 * (see https://tools.ietf.org/html/rfc1533)
 *
 * Summarising the format: the buffer is a sequence of options. All options
 * begin with a tag octet, which uniquely identifies the option.  Fixed-
 * length options without data consist of only a tag octet.  Only options PAD
 * (0) and END (255) are fixed length.  All other options are variable-length
 * with a length octet following the tag octet.  The value of the length
 * octet does not include the two octets specifying the tag and length.  The
 * length octet is followed by "length" octets of data.
 *
 * Option data may be a sequence of sub-options in the same format. The data
 * content of the encapsulating option is one or more encapsulated sub-options,
 * with no terminating END tag is required.
 *
 * To be valid, the top-level sequence of options should be terminated by an
 * END tag. The buffer should be padded with the PAD byte.
 *
 * When stored to NVRAM, the DHCP option format buffer is preceded by a
 * checksum octet. The full buffer (including after the END tag) contributes
 * to the checksum, hence the need to fill the buffer to the end with PAD.

/*
 * Packed stream mode is documented in SF-112241-TC.
 * The general idea is that, instead of putting each incoming
 * packet into a separate buffer which is specified in a RX
 * descriptor, a large buffer is provided to the hardware and
 * packets are put there in a continuous stream.
 * The main advantage of such an approach is that RX queue refilling
 * happens much less frequently.
 *
 * Equal stride packed stream mode is documented in SF-119419-TC.
 * The general idea is to utilize advantages of the packed stream,
 * but avoid indirection in packets representation.
 * The main advantage of such an approach is that RX queue refilling
 * happens much less frequently and packets buffers are independent
 * from upper layers point of view.
