41 /* DESCRIPTION */
42 /* */
43 /* This function causes the driver to be called from the IP helper */
44 /* thread in order to finish some deferred processing. A typical */
45 /* example of this is the transmit complete interrupt. Instead of */
46 /* loading the packet inside the transmit complete interrupt, the */
47 /* driver can setup some internal variables and call this routine */
48 /* to be called subsequently from the IP helper thread to finish */
49 /* the transmit complete interrupt processing. */
