82583V GbE Controller—Driver Programing Interface
9.2.7.12 Carrier Extension Error Count - CEXTERR (0x0403C; R)
9.2.7.13
Field
CEXTERR
Bit(s)
31:0
Initial
Value
0x0
Description
Number of packets received with a carrier extension error.
This register counts the number of packets received in which the carrier extension error
was signaled across the GMII interface. The PHY propagates carrier extension errors to
the MAC when an error is detected during the carrier extended time of a packet
reception. An extension error is signaled by the PHY by the encoding of 0x1F on the
receive data inputs while RX_ER is asserted to the MAC. This register only increments if
receives are enabled and the device is operating at 1000 Mb/s.
Receive Length Error Count - RLEC (0x04040; R)
Note:
9.2.7.14
Field
RLEC
Bit(s)
31:0
Initial
Value
0x0
Description
Number of packets with receive length errors.
This register counts receive length error events. A length error occurs if an incoming
packet passes the filter criteria but is undersized or oversized. Packets less than 64
bytes are undersized. Packets over 1522 bytes are oversized if LongPacketEnable is 0b.
The 82583V does not support setting LPE to 1b.
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.
XON Received Count - XONRXC (0x04048; R)
9.2.7.15
Field
XONRXC
Bit(s)
31:0
Initial
Value
0x0
Description
Number of XON packets received.
This register counts the number of XON packets received. XON packets can use the
global address, or the station address. This register only increments if receives are
enabled.
XON Transmitted Count - XONTXC (0x0404C; R)
Field
XONTXC
Bit(s)
31:0
Initial
Value
0x0
Description
Number of XON packets transmitted.
This register counts the number of XON packets transmitted. These can be either due
to queue fullness, or due to software initiated action (using SWXOFF). This register only
increments if transmits are enabled.
