TX-UUS-IMA
S/UNI-IMA-8 provides read access to the TX LSM in
RIPP link context records. Note after link start-up, it is
up to PM to put the LSM into UNUSABLE state.
R-131
RX-UUS-IMA
S/UNI-IMA-8 provides read access to the RX LSM in
link context records. Note after link start-up, it is up to
PM to put the LSM into UNUSABLE state.

TX-UUS-IMA-FE
S/UNI-IMA-8 may generate an interrupt once FE TX
LSM enters UNUSABLE state.
RX-UUS-IMA-FE S/UNI-IMA-8 may generate an interrupt once FE RX
LSM enters UNUSABLE state.
