1 not_deskew All RX lanes locked but the alignment markers were not unique or the skew was too
large.
This is an event signal, so use .not_align above instead to determine the alignment
state.
Restarts the synchronization.
Only applicable when RSFEC_CORE_CFG.frac = none (100GE/128GFC).

0 not_align RX lanes not aligned (state).
