This is the second commit of the implementation of the CFM protocol
according to 802.1Q section 12.14.
Functionality is extended with CCM frame transmission.
Interface is extended with these functions:
br_cfm_cc_rdi_set()
br_cfm_cc_ccm_tx()
br_cfm_cc_config_set()
A MEP Continuity Check feature can be configured by
br_cfm_cc_config_set()
The Continuity Check parameters can be configured to be used when
transmitting CCM.
A MEP can be configured to start or stop transmission of CCM frames by
br_cfm_cc_ccm_tx()
The CCM will be transmitted for a selected period in seconds.
Must call this function before timeout to keep transmission alive.
A MEP transmitting CCM can be configured with inserted RDI in PDU by
br_cfm_cc_rdi_set()
