Description
TCP/IP MAC Event.
TCP/IP MAC Events Codes.
This enumeration defines all the possible events that can be reported by the MAC to the stack.
Depending on the type of the hardware Ethernet/Wi-Fi interface, etc., not all events are possible.
Members
| Members | Description |
|---|---|
| TCPIP_MAC_EV_NONE = 0x0000 | no event. |
| TCPIP_MAC_EV_RX_PKTPEND = 0x0001 | RX triggered events: A receive packet is pending. |
| TCPIP_MAC_EV_RX_OVFLOW = 0x0002 | RX triggered events: RX FIFO overflow (system level latency, no descriptors, etc.). |
| TCPIP_MAC_EV_RX_BUFNA = 0x0004 | RX triggered events: no RX descriptor available to receive a new packet. |
| TCPIP_MAC_EV_RX_ACT = 0x0008 | RX triggered events: There's RX data available. |
| TCPIP_MAC_EV_RX_DONE = 0x0010 | RX triggered events: A packet was successfully received. |
| TCPIP_MAC_EV_RX_FWMARK = 0x0020 | RX triggered events: the number of received packets is greater than or equal to than the RX Full Watermark. |
| TCPIP_MAC_EV_RX_EWMARK = 0x0040 | RX triggered events: the number of received packets is less than or equal to than the RX Empty Watermark. |
| TCPIP_MAC_EV_RX_BUSERR = 0x0080 | RX triggered events: a bus error encountered during an RX transfer. |
| TCPIP_MAC_EV_TX_DONE = 0x0100 | TX triggered events: A packet was transmitted and its status is available. |
| TCPIP_MAC_EV_TX_ABORT = 0x0200 | TX triggered events: a TX packet was aborted by the MAC (jumbo/system underrun/excessive defer/late collision/excessive collisions). |
| TCPIP_MAC_EV_TX_BUSERR = 0x0400 | TX triggered events: a bus error encountered during a TX transfer. |
| TCPIP_MAC_EV_CONN_ESTABLISHED = 0x0800 | Connection triggered events: Connection established. |
| TCPIP_MAC_EV_CONN_LOST = 0x1000 | Connection triggered events: Connection lost. |
| TCPIP_MAC_EV_RX_ALL = (TCPIP_MAC_EV_RX_PKTPEND|TCPIP_MAC_EV_RX_OVFLOW| TCPIP_MAC_EV_RX_BUFNA|TCPIP_MAC_EV_RX_ACT| TCPIP_MAC_EV_RX_DONE|TCPIP_MAC_EV_RX_FWMARK| TCPIP_MAC_EV_RX_EWMARK|TCPIP_MAC_EV_RX_BUSERR) | Useful Masks: all RX related events. |
| TCPIP_MAC_EV_TX_ALL = (TCPIP_MAC_EV_TX_DONE|TCPIP_MAC_EV_TX_ABORT|TCPIP_MAC_EV_TX_BUSERR) | Useful Masks: all TX related events. |
| TCPIP_MAC_EV_RXTX_ERRORS = (TCPIP_MAC_EV_RX_OVFLOW|TCPIP_MAC_EV_RX_BUFNA| TCPIP_MAC_EV_RX_BUSERR|TCPIP_MAC_EV_TX_ABORT| TCPIP_MAC_EV_TX_BUSERR) | Abnormal traffic/system events: Action should be taken accordingly by the stack (or the stack user). |
| TCPIP_MAC_EV_CONN_ALL = (TCPIP_MAC_EV_CONN_ESTABLISHED|TCPIP_MAC_EV_CONN_LOST) | Mask of all Connection related events. |
