RX Flow Control2
To enable RX flow control, driver MUST set this bit & bit8 of RX_CFG.
1 = enable Rx Flow control
0 = disable
Reserved, must set to ‘0s’ for normal operation

JamLT
R/W
6’h0
Define Jam Limit for backpressure collision account.
Normally set this field at 19h. It can avoid HUB port going to partition state due to
too many collisions. AX88780 will skip one frame collision backpressure when
collision counter equal to JamLT. The collision count will be reset to zero when
every transmit frame with no collision or receive a frame with no backpressure
collision.

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.

Description
Reserved
Driver must set this field to 23’h7F_8000 in initial stage for normal
operation. It is used to re-transmit a pause-on frame when pause timer
expired and receive buffer still not enough.
