    e1000e: Add support for BM PHYs on ICH9 · 97ac8cae
    Bruce Allan authored
    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.
