DescriptionSR number

through igssn, the driver will drop such packets. But the guest is not aware of such drops and

it continues to expect send completion for those packets. This situation results in gradual
reduction of # of usable descriptors for igssn which causes performance degradation over a
period and eventually the igssn interface experiences a hang.
