It is probably a good idea to resend. It will make it easier for
Richard if the patches are in his mailbox.

Cc: Richard is not so obvious as it should be, since
./scripts/get_maintainers.pl would not of suggested it, since you are
not modify the PTP core. It takes a bit of experience to know this.

This is the second time something like this has happened recently for
Intel Ethernet drivers. The other case was making use of the LED
subsystem from within an Ethernet driver, and the LED subsystem
maintainers were not Cc:. It would be good if the Intel Maintainers
actually took notice of this, they have the experience to know better.

I noticed your patches are not threaded. Did you use git send-email?
It normally does thread a patchset. The threading keeps the patchset
together, which can be important for some of the bots which scoop up
patches in emails and run tests on them. Please see if you can fix
that in the resend.
