XON Received Count - XONRXC (0x04048; R)
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)
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.
XOFF Received Count - XOFFRXC (0x04050; R)
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)
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)
This register counts the number of unsupported flow control frames that are received.
