Main operation mode:
0 none: Non-fractured, supporting e.g. 100GE, 128GFC:
One client using all 4 physical lanes.
Register tables indexed by physical lane# only uses entry 0, unless otherwise specified.

indic_byp
Bypass error indication (to reduce latency):
0: Sync headers in the 66b words extracted from uncorrectable FEC codewords are
deliberately invalidated.
1: 66b words extracted from uncorrectable codewords are not explicitly marked bad.
When number of symbol errors in a block of 8192 consecutive codewords has
exceeded 417 with RS528 and 6380 with RS544, then sync header errors will be
generated towards the PCS layer for a period of 60ms to 75ms.
