This results in a panic when the send completion runs. The\nexact panic varies depending on what elements of the container structure\nget corrupted. The fix is to use the correct expression in\n_pad_sdma_tx_descs() to test the need to expand the descriptor array.\n\nWith this patch the crashes are no longer reproducible and the machine is\nstable.",
