Subject: Re: [PATCH net-2.6 2/2] sfc: SFE4002/SFN4112F: Widen temperature
 and voltage tolerances

From: Ben Hutchings <>
Date: Fri, 19 Feb 2010 23:34:03 +0000

> The temperature and voltage limits currently set on these boards are
> too conservative and will cause the driver to stop the net device
> erroneously in some systems.
> Based on a review of the chip datasheets and advice from the designer
> of these boards:
> - Raise the maximum board temperatures to the specified maximum ambient
>   temperatures for their PHYs plus the expected temperature bias of the
>   board
> - Raise the maximum controller temperature to 90 degrees
> - Lower the minimum temperatures to 0 degrees
> - Widen the voltage tolerances to at least +/- 10%
