pure virtual |
Gets memory buffer alignment preference.
Gets preferred memory buffer alignment of the EMAC device. IP stack may or may not align link out memory buffer chains using the alignment.
Implemented in EMW3080B_EMAC, and WICED_EMAC.
|
pure virtual |
Return interface name.
name | Pointer to where the name should be written |
size | Maximum number of character to copy |
Implemented in EMW3080B_EMAC, and WICED_EMAC.
|
pure virtual |
Returns size of the underlying interface HW address size.
Implemented in EMW3080B_EMAC, and WICED_EMAC.
|
pure virtual |
Return interface-supplied HW address.
Copies HW address to provided memory, addr
has to be of correct size see get_hwaddr_size
HW address need not be provided if this interface does not have its own HW address configuration; stack will choose address from central system configuration if the function returns false and does not write to addr.
addr | HW address for underlying interface |
Implemented in EMW3080B_EMAC, and WICED_EMAC.
|
pure virtual |
Set HW address for interface.
Provided address has to be of correct size, see get_hwaddr_size
Called to set the MAC address to actually use - if get_hwaddr is provided the stack would normally use that, but it could be overridden, for example for test purposes.
addr | Address to be set |
Implemented in EMW3080B_EMAC, and WICED_EMAC.
|
pure virtual |
Sends the packet over the link.
That can not be called from an interrupt context.
buf | Packet to be send |
