e1000e: Add support for BM PHYs on ICH9
This patch adds support for the BM PHY, a new PHY model being used on ICH9-based implementations. This new PHY exposes issues in the ICH9 silicon when receiving jumbo frames large enough to use more than a certain part of the Rx FIFO, and this unfortunately breaks packet split jumbo receives. For this reason we re-introduce (for affected adapters only) the jumbo single-skb receive routine back so that people who do wish to use jumbo frames on these ich9 platforms can do so. Part of this problem has to do with CPU sleep states and to make sure that all the wake up timings are correctly we force them with the recently merged pm_qos infrastructure written by Mark Gross. (See http://lkml.org/lkml/2007/10/4/400). To make code read a bit easier we introduce a _IS_ICH flag so that we don't need to do mac type checks over the code.
