Issue Description

We are doing DVB-C with a MA5800 and a MA5633.
Now we want to change the symbol-rate from 6.875 to 6.900 because in Germany the default symbol rate Receivers are scanning is 6900.
I tried to create a test eqam-channel with the new symbol-rate and getting following error.
          cable eqam-channel 29 symbol-rate 6.900
  This operation will take several minutes, Please wait...
  Failure: The number of EQAM symbol-rate exceeds the system's actual capability


The symbol-rate 6.900 is special, it can be only configured without any other symbol-rate. This is a limitation of hardware.
  So, please delete all the configurations of current symbol-rate 6.875 first, after all the symbol-rate are deleted, then try to configure 6.900 again.
Example of delete channel 1:
Interface cable  frame x   //frame id
         cable eqam-channel  1  disable
Undo cable eqam-channel 1 frequency
