Here is experimental patch for BCM57765 family controllers. I
don't have these controllers so the patch was not tested at all
except compile. Recent Broadcom controllers like BCM57765 support
EEE(Energy Efficient Ethernet) feature but it is not yet supported
by the patch.
Also it would good to see the output of "pciconf -lcbv" and dmesg
after applying the patch.
