* Name: pkt_input
|
|
*
|
|
* Description:
|
|
* Handle incoming packet input
|
|
*
|
|
* This function provides the interface between Ethernet device drivers and
|
|
* packet socket logic. All frames that are received should be provided to
|
|
* pkt_input() prior to other routing.
|
|
*
|
|
* Parameters:
|
|
* dev - The device driver structure containing the received packet
|
|
*
|
|
* Return:
|
|
* OK The packet has been processed and can be deleted
|
|
* ERROR There is a matching connection, but could not dispatch the packet
|
|
* yet. Useful when a packet arrives before a recv call is in
|
|
* place.
|
|
*
|
|
* Assumptions:
|
|
* Called from the network diver with the network locked.
