> Subject: [PATCH] e1000e: fix timing for 82579 Gigabit Ethernet controller
>
> After an upgrade to Linux kernel v4.x the hardware timestamps of the
> 82579 Gigabit Ethernet Controller are different than expected.
> The values that are being read are almost four times as big as before
> the kernel upgrade.
>
> The difference is that after the upgrade the driver sets the clock
> frequency to 25MHz, where before the upgrade it was set to 96MHz. Intel
> confirmed that the correct frequency for this network adapter is 96MHz.
