9.2.7.16 XOFF Received Count - XOFFRXC (0x04050; R)
9.2.7.17
Field
XOFFRXC
Bit(s)
31:0
Initial
Value
0x0
Description
Number of XOFF packets received.
This register counts the number of XOFF packets received. XOFF packets can use the
global address, or the station address. This register only increments if receives are
enabled.
XOFF Transmitted Count - XOFFTXC (0x04054; R)
9.2.7.18
Field
XOFFTXC
Bit(s)
31:0
Initial
Value
0x0
Description
Number of XOFF packets transmitted.
This register counts the number of XOFF 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.
FC Received Unsupported Count - FCRUC (0x04058; RW)
9.2.7.19
Field
FCRUC
Bit(s)
31:0
Initial
Value
0x0
Description
Number of unsupported flow control frames received.
This register counts the number of unsupported flow control frames that are received.
The FCRUC counter is incremented when a flow control packet is received that matches
either the reserved flow control multicast address (in FCAH/L) or the MAC station
address, and has a matching flow control type field match (to the value in FCT), but has
an incorrect op-code field. This register only increments if receives are enabled.
Packets Received [64 Bytes] Count - PRC64 (0x0405C; RW)
Field
PRC64
Bit(s)
31:0
Initial
Value
0
Description
Number of packets received that are 64 bytes in length.
This register counts the number of good packets received that are exactly 64 bytes
(from <Destination Address> through <CRC>, inclusively) in length. Packets that are
counted in the Missed Packet Count register are not counted in this register. This
register does not include received flow control packets and increments only if receives
are enabled.
