The existing logic is as is for a reason. There is no need to change
it to satisfy the main purpose of your patchset?

It is structured as one bit to test whether a timestamp is requested
and another to select among two variants usec/nsec. Just add another
layer of branching between new/old in cases where this distinction is
needed.

Please avoid code churn unless needed.

This patch makes it easier to add logic for 2 new socket time options.
But, if you prefer for all of the options to depend on SOCK_RCVTSTAMP
then I will drop it.
