Packets over 1518/1522/1526 bytes are oversized if LPE is 0b. If LPE is 1b, then an incoming packet is
considered oversized if it exceeds RLPML.LPML bytes.
If receives are not enabled, this register does not increment. These lengths are based on bytes in the
received packet from <Destination Address> through <CRC>, inclusively.
Note: The maximum size of a packet when LPE is 0b is fixed according to the
CTRL_EXT.Extended_VLAN bit and the detection of a VLAN tag in the packet.
14.9.36 Management Packets Received Count - MNGPRC
(040B4h; RC)
This register counts the total number of packets received that pass the management filters as
described in the Total Cost of Ownership (TCO) System Management Bus Interface Application Note.
Any packets with errors are not counted, except packets that are dropped because the management
receive FIFO is full.
14.9.37 Management Packets Dropped Count - MPDC
(040B8h; RC)
This register counts the total number of packets received that pass the management filters as
described in the Total Cost of Ownership (TCO) System Management Bus Interface Application Note and
then are dropped because the management receive FIFO is full. Management packets include any
packet directed to the manageability console (for example, BMC and ARP packets).
14.9.38 Management Packets Transmitted Count -
MNGPTC (040BCh; RC)
This register counts the total number of transmitted packets originating from the manageability path.
