Description
No Abort
When this bit is enabled, MAC will keep retry transmit current frame even
excessive collision otherwise it will abort current transmission due to
excessive collision.

TX Pause Time out
It is used to re-transmit a pause-on frame when pause timer expired and
receive buffer still not enough.
In 32-bit mode, this field should be set to 0x1F_E000 at 1000Mbps mode
and set to 0x7F_8000 at 10/100Mbps modes.
In 16-bit mode, this field should be set to 0xFFFF at 10/100/1000Mbps
modes. (Note: The bit 16 ~ 22 of this field are invalid in 16-bit mode.)

Description

RX Remainder Capacity Low-Bound
This field defines as the remainder capacity of RX buffer for pause
operation. If the flow control (bit12 of MAC_CFG0) is enabled, MAC will
send pause frame when the available space of receive buffer is less than
this value. The unit is 16-byte.

Description
Reserved
RX Remainder Capacity Upper-Bound
This field defines as upper bound of remainder size of RX buffer for pause
operation. If the flow control is enabled, MAC will stop to send pause
frame until the available space of receive buffer is more than this value.
The unit is 16-byte.
