This function is used to enable OAM functions (other than loopback) for a
particular channel. The channel (embedded within OamConfig - see below) must
have been configured for firmware OAM (not host OAM) for these configurations
to take effect. More than one function may be enabled at one time.
If more than one function is enabled, they must all be of the same level, all
F4(VP) or all F5(VC).
The usage of the OamConfig parameter is described through the table below. To
initiate firmware OAM, set one or more bits in OamConfig corresponding to the
various OAM functions. To disable firmware OAM functions, set bit 30 along
with any other combination of bits to shutdown various OAM functions at once.
e2e - end to end, seg - segment, CC - continuity check,
AIS - Alarm Indication Signal
