That driver, e1000e, uses a plain old "work" to process the Tx time stamp. Plain "work' runs at the lowest priority in Linux. On a busy system, even higher delays than 100 ms are possible. The way to fix this is change the driver to use the PTP kworker thread by moving the "work" code to the .do_aux_work callback. Then you can set the kernel thread's schedule to SCHED_FIFO at high priority using the chrt command.
