bridge: cfm: Kernel space implementation of CFM. CCM frame TX added.
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()
