Module Name:    src
Committed By:   jmcneill
Date:           Wed Apr 19 00:20:02 UTC 2017

Modified Files:
        src/sys/dev/ic: rtl8169.c rtl81x9reg.h rtl81x9var.h
        src/sys/dev/pci: if_re_pci.c

Log Message:
Performance improvements for PCIe and 8168 based devices:
 - When using the countdown timer for interrupt moderation on PCIe devices,
   use a timer rate value based on a 125MHz PCIe reference clock instead of
   33 MHz.
 - For 8168 based devices, ditch the countdown timer and instead use the
   (undocumented) hardware interrupt moderation feature.
 - Support TSOv4 on 8168D and later devices.
