Field Documentation

volatile uint32_t rflpc_eth_rx_status_t::status_hash_crc

hash CRC calculated from source and destination address.

• Bits 8:0 : CRC calcultated from the source address
• Bits 24:16 : CRC calcultated from the destination address

Definition at line 155 of file ethernet.h.

volatile uint32_t rflpc_eth_rx_status_t::status_info

Receive status return flags.

• Bits 10:0 : Size of the received data (-1 encoded)
• Bit 18 : Control frame
• Bit 19 : VLAN frame
• Bit 20 : Fail frame filter. The remainder of the frame will be discarded
• Bit 21 : Multicast frame
• Bit 22 : Broadcast frame
• Bit 23 : CRC error
• Bit 24 : Symbol error reported by PHY
• Bit 25 : Length Error
• Bit 26 : Range error
• Bit 27 : Alignement erro
• Bit 28 : Receive overrun
• Bit 29 : No more descriptor and the frame is to big to fit in the data buffer
• Bit 30 : Last flag. This is the last fragment of the frame
• Bit 31 : Error occured.
