[ Upstream commit b6d49cab44b567b3e0a5544b3d61e516a7355fad ]
Commit d1cbfd771ce8 ("ptp_clock: Allow for it to be optional") changed
all PTP-capable Ethernet drivers from `select PTP_1588_CLOCK` to `imply
PTP_1588_CLOCK`, "in order to break the hard dependency between the PTP
clock subsystem and ethernet drivers capable of being clock providers."
I don't think this one should be backported unless 3a9dd3ecb207 ("kconfig:
make 'imply' obey the direct dependency") is already backported to v5.6
(which I don't think it should either).
