This change adds support for the Linux PTP Hardware clock and timestamping functionality provided by the hardware. There are actually two cases that this timestamping is meant to support. The first case would be an ordinary clock scenario. In this configuration the host interface does not have access to BAR 4. However all of the host interfaces should be locked into the same boundary clock region and as such they are all on the same clock anyway. With this being the case they can synchronize among themselves and only need to adjust the offset since they are all on the same clock with the same frequency. The second case is a boundary clock scenario. This is a special case and would require both BAR 4 access, and a means of presenting a netdev per boundary region. The current plan is to use DSA at some point in the future to provide these interfaces, but the DSA portion is still under development.
