Description

PIC32C Received Packet Status.

This structure contains the status of a PIC32C received packet.

Members

MembersDescription

offset : 2Receive buffer offest, bits 13:12 of frame length for jumbo frame.
bSof : 1Start of frame.
bEof : 1End of frame.
bCFI : 1Concatenation Format Indicator.
vlanPriority : 3VLAN priority (if VLAN detected).
bPriorityDetected : 1Priority tag detected.
bVlanDetected : 1< VLAN tag detected.
bTypeIDMatch : 1< Type ID match.
bAddr4Match : 1< Address register 4 match.
bAddr3Match : 1< Address register 3 match.
bAddr2Match : 1< Address register 2 match.
bAddr1Match : 1< Address register 1 match.

Remarks

MACs have different hardware support for the received packet status.
