Re: [patch] usbnet: add timestamping support

Quoting Michael Riesch [off-list ref]:

I considered to put these calls between #ifdef's to make them dependent
on CONFIG_NETWORK_PHY_TIMESTAMPING. I decided not to do so because except
the check whether the current packet is a PTP packet (and this check
should be fast) no overhead occurs. But let me know your opinion about
that one.

Come to think of it the #ifdef's are definitely unnecessary because these
functions are no-ops with CONFIG_NETWORK_PHY_TIMESTAMPING not set.

Michael
