#
# 4.2 Options
#
# Two of the currently-defined extension headers -- the Hop-by-Hop
# Options header and the Destination Options header -- carry a variable
# number of type-length-value (TLV) encoded "options", of the following
# format:
#
# +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+- - - - - - - - -
# | Option Type | Opt Data Len | Option Data
# +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+- - - - - - - - -
#
# Option Type 8-bit identifier of the type of option.
#
# Opt Data Len 8-bit unsigned integer. Length of the Option
# Data field of this option, in octets.
#
# Option Data Variable-length field. Option-Type-specific
# data.
#
# =begin html
#
# The sequence of options within a header must be processed strictly in
# the order they appear in the header; a receiver must not, for
# example, scan through the header looking for a particular kind of
# option and process that option prior to processing all preceding
# ones.
#
#
# =end html
#
# The Option Type identifiers are internally encoded such that their
# highest-order two bits specify the action that must be taken if the
# processing IPv6 node does not recognize the Option Type:
#
# 00 - skip over this option and continue processing the header.
#
# =begin html
#
# 01 - discard the packet.
#
#
# =end html
#
# 10 - discard the packet and, regardless of whether or not the
# packet's Destination Address was a multicast address, send an
# ICMP Parameter Problem, Code 2, message to the packet's
# Source Address, pointing to the unrecognized Option Type.
#
# 11 - discard the packet and, only if the packet's Destination
# Address was not a multicast address, send an ICMP Parameter
# Problem, Code 2, message to the packet's Source Address,
# pointing to the unrecognized Option Type.
#
# The third-highest-order bit of the Option Type specifies whether or
# not the Option Data of that option can change en-route to the
# packet's final destination. When an Authentication header is present
# in the packet, for any option whose data may change en-route, its
# entire Option Data field must be treated as zero-valued octets when
# computing or verifying the packet's authenticating value.
#
# 0 - Option Data does not change en-route
#
# 1 - Option Data may change en-route
#
# The three high-order bits described above are to be treated as part
# of the Option Type, not independent of the Option Type. That is, a
# particular option is identified by a full 8-bit Option Type, not just
# the low-order 5 bits of an Option Type.
#
# The same Option Type numbering space is used for both the Hop-by-Hop
# Options header and the Destination Options header. However, the
# specification of a particular option may restrict its use to only one
# of those two headers.
#
# Individual options may have specific alignment requirements, to
# ensure that multi-octet values within Option Data fields fall on
# natural boundaries. The alignment requirement of an option is
# specified using the notation xn+y, meaning the Option Type must
# appear at an integer multiple of x octets from the start of the
# header, plus y octets. For example:
#
# 2n means any 2-octet offset from the start of the header.
# 8n+2 means any 8-octet offset from the start of the header,
# plus 2 octets.
