XOnLimit
X-ON Limit - When Flow control is enabled, the GT-482xx
will send X-ON packet when the number of buffers for this
port going below (XOnLimit * 8) value
0x3 @1M (24)
0x43 @4M
(536)
31:24
HolLimit
HOL Limit - the GT-482xx discards packet when the Tx
queue exceeds TxThr limit and the number of buffers allo-
cated to this port exceed (HolLimit * 8)
0x7 @1M (56)
0x43 @4M
