    ldmvsw: disable tso and gso for bridge operations · bc221a34
    Shannon Nelson authored
    The ldmvsw driver is specifically for supporting the ldom virtual
    networking by running in the primary ldom and using the LDC to connect
    the remaining ldoms to the outside world via a bridge.  With TSO and GSO
    supported while connected the bridge, things tend to misbehave as seen
    in our case by delayed packets, enough to begin triggering retransmits
    and affecting overall throughput.  By turning off advertised support for
    TSO and GSO we restore stable traffic flow through the bridge.
