The HIT_SUITE_LIST Parameter from HIPv2 (
http://tools.ietf.org/html/draft-ietf-hip-rfc5201-bis-08 ) is unsupported.
C&P from the draft:
5.2.10. HIT_SUITE_LIST
The HIT_SUITE_LIST parameter contains a list of the supported HIT
suite IDs of the Responder. The Responder sends the HIT_SUITE_LIST
in the signed part of the R1 packet. Based on the HIT_SUITE_LIST,
the Initiator can determine which source HITs are supported by the
Responder.

Length number of HIT Suite IDs
ID defines a HIT Suite ID supported by the host.
The list of IDs is ordered by preference of the
host. Each HIT Suite ID is one octet long. The four
higher-order bits of the ID field correspond to the
HIT Suite ID in the ORCHID OGA field. The four
lower-order bits are reserved and set to 0 and
ignored by the receiver.
The HIT Suite ID indexes a HIT Suite. HIT Suites are composed of
signature algorithms as defined in Section 5.2.9 and hash functions.
The ID field in the HIT_SUITE_LIST is defined as eight-bit field as
opposed to the four-bit HIT Suite ID and OGA field in the ORCHID.
This difference is a measure to accommodate larger HIT Suite IDs if
the 16 available values prove insufficient. In that case, one of the
16 values, zero, will be used to indicate that four additional bits
of the ORCHID will be used to encode the HIT Suite ID. Hence, the
current four-bit HIT Suite-IDs only use the four higher order bits in
the ID field. Future documents may define the use of the four lower-
order bits in the ID field.
The following HIT Suites ID are defined:
HIT Suite ID
RESERVED 0
RSA,DSA/SHA-256 1 (REQUIRED)
ECDSA/SHA-384 2 (RECOMMENDED)
ECDSA_LOW/SHA-1 3 (RECOMMENDED)
