This patchset adds the support for PHC (PTP Hardware Clock)
in the ENA driver. The documentation part of the patchset
includes additional information, including statistics,
utilization and invocation examples through the testptp
utility.

David Arinzon (8):
 net: ena: Add PHC support in the ENA driver
 net: ena: PHC silent reset
 net: ena: Add device reload capability through devlink
 devlink: Add new "enable_phc" generic device param
 net: ena: Control PHC enable through devlink
 net: ena: Add debugfs support to the ENA driver
 net: ena: View PHC stats using debugfs
 net: ena: Add PHC documentation

Could you please add very simple devlink_port instance of flavour
PHYSICAL and link it with netdev? Having devlink instance without the
port related to the netdev looks a bit odd.

Thanks!
