    Subject[ 03/78] tg3: Fix 5717 serdes powerdown problem
    3.3-stable review patch.  If anyone has any objections, please let me know.

    ------------------


    From: Matt Carlson <mcarlson@broadcom.com>

    [ Upstream commit 085f1afc56619bda424941412fdeaff1e32c21dc ]

    If port 0 of a 5717 serdes device powers down, it hides the phy from
    port 1. This patch works around the problem by keeping port 0's phy
    powered up.
