    bonding: correctly process non-linear skbs · ab12811c
    Andy Gospodarek authored
    It was recently brought to my attention that 802.3ad mode bonds would no
    longer form when using some network hardware after a driver update.
    After snooping around I realized that the particular hardware was using
    page-based skbs and found that skb->data did not contain a valid LACPDU
    as it was not stored there.  That explained the inability to form an
    802.3ad-based bond.  For balance-alb mode bonds this was also an issue
    as ARPs would not be properly processed.
    This patch fixes the issue in my tests and should be applied to 2.6.36
    and as far back as anyone cares to add it to stable.
    Thanks to Alexander Duyck <alexander.h.duyck@intel.com> and Jesse
    Brandeburg <jesse.brandeburg@intel.com> for the suggestions on this one.
