Function Documentation

int RawEthRxPacket

(

PBM_Handle

hPkt

)

Description
This routine is the API interface routine which is called by the NIMU layer when the ethernet type doesnt match any of the well know standard ethernet types. This function checks if a raw ethernet socket object exists for the ethernet type in the packet and if so enqueus in the socket buffer for the application to receive.

Parameters:

[in]

hPkt

Handle to the packet which is to be passed up the NDK stack.

Return values:

	-1	- Error
	0	- Success

int RawEthTxPacket	(	HANDLE	hRawEthSock,
		char *	pBuffer,
		int	len
	)

Description
The function is the interface routine which is called to send a packet via a raw ethernet socket object.

Parameters:

[in]	hRawEthSock	Handle to the Raw ethernet socket.
[in]	pBuffer	Handle to the data buffer that needs to be sent
[in]	len	length of the data

Return values:

0

- Successfully sent out the packet. ENOBUFS - Error allocating memory for the packet. Packet not sent out.

int RawEthTxPacketNC	(	HANDLE	hRawEthSock,
		char *	pBuffer,
		int	len,
		HANDLE	hPkt
	)

Description
The function is the interface routine which is called to send a packet without any copy via a raw ethernet socket object.

Parameters:

[in]	hRawEthSock	Handle to the Raw ethernet socket.
[in]	pBuffer	Handle to the data buffer that needs to be sent
[in]	len	length of the data
[in]	hPkt	Handle to the packet that needs to be sent

Return values:

0

- Successfully sent out the packet. EINVAL - Bad Packet / Buffer handles, packet not sent out.
