this patch uses grep to test whether the net_tstamp.h header has HWTSTAMP_TX_ONESTEP_SYNC flag defined. If it doesn't then we can simply define it with the correct value. This works because proper drivers should just report that the value is not allowed if they don't support onestep mode. This is the cleanest way to ensure that linuxptp will still work on kernels which have not defined the one step flag, and also works for any distributions which backport the feature.
