Bits 0-15: WAN Queue Overflow Interrupt Mask (WQOIM[16-1]) This register provides an interrupt bit mask to
filter out unwanted interrupts.

1A4h:
Default
Bits 0-15: WAN Queue Near Full Status (WQNFS[16-1]) This register indicates whether an impending overflow
condition has occurred on a WAN Queue, and the device initiated the discarding of incoming frames on a WAN
interface. This condition can occur if the transmit LAN interface is disabled, if the MAC has received excessive
pause flow control frames and completely filled the buffers for the transmit LAN while responding to the pause
requests, or if operating in half duplex mode with heavy LAN network congestion. This register is cleared each time
it is read.

0 = Bit mask disabled
1 = Bit mask enabled
0 = Normal operation
1 = At least one “Near Full” condition detected since last read, frames may have been discarded.
