Subject: [PATCH net-next v2 01/11] ice: prefix clock timer command enumeration values with ICE_PTP
From: Sergey Temerkhanov <sergey.temerkhanov@...el.com>
The ice driver has an enumeration for the various commands that can be
programmed to the MAC and PHY for setting up hardware clock operations.
Prefix these with ICE_PTP so that they are clearly namespaced to the ice
driver.
