Enumeration: 'clk2mb': 2500000, 'clk125k': 125000, 'clk19200b': 19230, 'clk32000b': 32051, 'clk833k': 833333, 'clk5mb': 5000000, 'clk1mb': 1250000, 'clk1200b': 1200, 'clk230k': 227272, 'clk2400b': 2401, 'clk625k': 625000, 'clk38400b': 38461, 'clk64k': 64102, 'clk420k': 416666, 'clk9600b': 9615, 'clk4800b': 4807, 'clk7200b': 7204, 'clk56k': 56818.

Allows control over the DMA burst cycle duration on MK5025 based products. This attribute is ignored for AN and ASN products. The default is always 8 short word bursts (ENABLED). There are only two cases in which this attribute should be changed. Case 1: In certain cases with DSDE and DSE link modules when one or both of the ethernet ports are suffering from excessive TxUflo or RxOflo errors, the BurstCount of one or both SYNC interfaces can be set to single short word bursts (DISABLED). The only modules for which this may be necessary are the DSDE (5430 - Dual Sync, Dual Enet) (module ID 112) and the DSE (5420 - Dual Sync, Single Enet) (module ID 116). If after making the change, the TxUflo or RxOflo errors persist on the ethernet or this SYNC interface starts to get UnderFlowTx or OverFlowRx errors, then the Link Module is overloaded and a more significant software configuration change or a hardware configuration change is needed. Case 2: When a SYNC interface on an mk5025 based Link Module is getting UnderFlowTx or OverFlowRx errors while running at bandwidths greater than 2Mbps, the errors may be eliminated by setting this attribute to unlimited burst mode (UNLIMITED). If after making the change, the errors persist or the same errors start on another SYNC interface or one of the ethernet interfaces on the same module starts to get TxUflo or RxOflo errors, then the Link Module is overloaded and a more significant software configuration change or a hardware configuration change is needed. For 6Mbps full duplex operation, this attribute will most likely need to be set to UNLIMITED and all other interfaces on this module will most likely have to be deconfigured. Enumeration: 'disabled': 2, 'unlimited': 3, 'enabled': 1.

FLAGSTREAMING will cause the fill character to alternate between Flags (0x7E) and Idles (0xFF), depending upon the current state of the line. For ISDN BRI Lines, DEFAULT, FORCE IDLES and FLAGSTREAMING all result in Idles (0xFF) as the fill character. For all other line types, DEFAULT, FORCE HDLC FLAGS and FLAGSTREAMING all result in HDLC Flags (0x7E) as the fill character. Leave this field at the default unless required for the attached device.
