This is very interesting and I'm curious to see how you balance the
tx and rx values. If I know the expected delay is x and I measure
delay y, how do I distribute the (x-y) difference to the tx and rx
comp values? Is there some symmetry in the RX and TX timestamping
error?
Anyway, could you please confirm the new txcomp and rxcomp options in
the hwtimestamp directive work for you as expected?
