19 * txdesc header.
20 * FIX: This might need own value that would be allocated especially for Prism2
21 * txdesc; ETH_P_CONTROL is commented as "Card specific control frames".
22 * However, these skb's should have only minimal path in the kernel side since
23 * prism2_send_mgmt() sends these with dev_queue_xmit() to prism2_tx(). */
