[E1000-devel] [PATCH net-next V3 1/2] igb: add PTP Hardware Clock code

This patch adds a source file implementing a PHC. Only the basic clock operations have been implemented, although the hardware would offer some ancillary functions. The code is fairly self contained and is not yet used in the main igb driver. Every timestamp and clock read operation must consult t

[E1000-devel] [PATCH net-next V3 0/2] igb: ptp hardware clock

* ChangeLog ** V3 - Driver compiles even without CONFIG_PTP_1588_CLOCK. - Timestamping always works, even when PTP code missing or fails. ** V2 - Fixed wrong bit shifting in the 82576 code. - Explained the timestamp locking with a comment in the code. - Preserved the comments from th
