PTP Limitations
---------------
NICs using the Intel Ice NIC driver may report the following in the ``ptp4l``
logs, which might coincide with a |PTP| port switching to ``FAULTY`` before
re-initializing.

ptp4l[80330.489]: timed out while polling for tx timestamp
ptp4l[80330.489]: increasing tx_timestamp_timeout may correct this issue, but it is likely caused by a driver bug
This is due to a limitation of the Intel Ice driver. The recommended workaround
is to set the ``tx_timestamp_timeout`` parameter to 700 (ms) in the ``ptp4l``
config.
