The Linux kernel supports a hardware time stamping mode that allows
sending a one step sync message. This commit adds support for this mode
by expanding the time stamp type enumeration. In order to enable this
mode, the configuration must specify both hardware time stamping and set
the twoStepFlag to false.
We still do not support the one step peer delay request mechanism since
there is neither kernel nor hardware support for it at this time.

Although the UDP/IPv4 layer does not need any state per instance (other
than the two file descriptors), the raw Ethernet layer will need this.
