Fix CMIS and preemphasis lane mapping issues #508

Open jemifdo opened 4 months ago

jemifdo commented 4 months ago

CMIS port db is updated dynamically on DPB
check_datapath_init_pending is disabled as it need to be done for different lanes sequentially instead of concurrent
Preemphasis to lane map now works when not all lanes of the port are used
get_physical_to_logical is now sorted to generated the correct preemphasis values

@prgeor I mean the case where 1x100G breakout mode is used in an 8 lane port (with speed 25G per lane) and for this the preemphasis dict must have values only the first four lanes. Remaining 4 lanes are unused by the port.
