RX_LID_ALLOC
32 bit vector in which each bit indicates
whether the LID value represented by
the bit index is occupied. For example,
Bit 31 corresponds to LID value 31, bit
0 corresponds to LID 0, and so on.
‘0’: LID has not been allocated to any
links.
‘1’: LID has been allocated to one of
the RX links in the group.

Last_Scci_phy_link
_id
Physical link ID of the rx link on which
the last “analyzable” ICP cell comes. A
ICP cell is considered analyzable if
1). the current processing cycle is ICP
and
2). the ICP cell is valid, and
3). the ICP cell carries a new SCCI, or
the ICP cell comes from the same link
of the last analyzed ICP cell; and
4). RX_IMA_ID matches the configured
value (or if no value is configured, the
value captured from the first ICP cell if
group is started/restarted)

RX_TRL_VALID
This indicates whether in the RX IDCC
the TRL of the current group has been
turned on or not. TRL is identified by
the RX_TRL_PHY_ID field, which is
translated from the TX_TRL_ LID in the
incoming ICP cells, after it is validated
by RIPP. ‘0’: Invalid. TRL off.
