Subject: [PATCH net-next V2 0/4] igb: auxiliary PHC functions for the i210.

From: Richard Cochran <>

* ChangeLog
** V2
   - Add missing serialization in the reset function
   - Reset the auxiliary functions along with the rest
   - Guard against spurious SYS_WRAP interrupts (these occur in the
     82580 device from time to time)

This patch series adds three features: time stamping external events,
producing a periodic output signal, and an internal PPS event. The
i210 PCIe card has a 6 pin header with SDP0-3, making it easy to try
out this new functionality.

An earlier version of this series was posted way back in May, 2013,
but that version lacked a good way to assign functions to the pins. In
the mean time, the PHC core has a standard method to configure the
pins, and this series makes use of it.


Richard Cochran (4):
  igb: refactor time sync interrupt handling
  igb: serialize access to the time sync interrupt registers.
  igb: enable internal PPS for the i210.
  igb: enable auxiliary PHC functions for the i210.
