By default, the NIC operates at autosense.
Note that only 1000mbps_fd and 1000mbps_hd
types are available for fiber adapter.
vlan=x - Specifies the VLAN ID. If vlan=0, the
vlan=[0|1] - Specifies the VLAN ID. If vlan=0, the
Virtual Local Area Network (VLAN) function is
disable.
jumbo=x - Specifies the jumbo frame support. If jumbo=1,
jumbo=[0|1] - Specifies the jumbo frame support. If jumbo=1,
the NIC accept jumbo frames. By default, this
function is disabled.
Jumbo frame usually improve the performance
int gigabit.
int_count - Rx frame count each interrupt.
int_timeout - Rx DMA wait time for an interrupt. Proper
values of int_count and int_timeout bring
rx_coalesce=n - Rx frame count each interrupt.
rx_timeout=n - Rx DMA wait time for an interrupt. Proper
values of rx_coalesce and rx_timeout bring
a conspicuous performance in the fast machine.
Ex. int_count=5 and int_timeout=750
Ex. rx_coalesce=5 and rx_timeout=750
tx_coalesce=n - Tx transmit count each TxComp interrupt.
Setting value larger than 1 will improve
performance, but this is possible to lower
stability in slow UP machines. By default,
tx_coalesce=1. (dl2k)
tx_flow=[1|0] - Specifies the Tx flow control. If tx_flow=1,
the Tx flow control enable.
rx_flow=[1|0] - Specifies the Rx flow control. If rx_flow=1,
the Rx flow control enable.
