API Call Reference List of APIs
unsigned int
value
32 bit value.
OUTPUT The set bits in the value parameter are reset in the configuration
register.
RETURN None.
unsigned int ethernetGetConfigReg(ETH_PORT ethPortNum)
This function returns the configuration register value of the given
ethernet port.
INPUT
ETH_PORT
ethPortNum
OUTPUT None.
Ethernet Port number. See ETH_PORT enum.
RETURN Port configuration register value.
bool etherInitRxDescRing(ETH_PORT_INFO *pEthPortCtrl, ETH_QUEUE rxQueue,int
rxDescNum, int rxBuffSize,unsigned int rxDescBaseAddr,unsigned int
rxBuffBaseAddr)
This function prepares a Rx chained list of descriptors and packet
buffers in a form of a ring. The routine must be called after port
initialization routine and before port start routine. The Ethernet
SDMA engine uses CPU bus addresses to access the various
devices in the system (i.e. DRAM). This function uses the ethernet
struct 'virtual to physical' routine (set by the user) to set the ring
with physical addresses.
INPUT
ETH_PORT_INFO
*pEthPortCtrl
ETH_QUEUE
rxQueue
Ethernet Port Control struct.
Number of Rx queue.
int rxDescNum Number of Rx descriptors
