ˆ rx_max_coalesce_frames
Configures the number of received frames before the NIC generates
receive interrupt. The valid range is from 0 to 100 and the default is 15.
This parameter and rx_coalesce_ticks cannot both have a value of 0. If
both parameters are set to 0, no receive interrupts are generated. It
should also be set significantly lower than rx_std_desc_cnt (and
rx_jumbo_desc_cnt if using jumbo frames). This parameter is not used
and is adjusted automatically if adaptive_coalesce is set to 1.
ˆ tx_coalesce_ticks
Configures the number of 1 usec ticks before the NIC generates
transmit interrupt after transmitting a frame. This parameter works in
conjunction with the tx_max_coalesce_frames parameter. Interrupt is
generated when either of these thresholds is exceeded. A value of 0
means this parameter is ignored and an interrupt is generated when
the tx_max_coalesce_frames threshold is reached. The valid range is
from 0 to 500 and the default is 400. This parameter is not used and is
adjusted automatically if adaptive_coalesce is set to 1.
ˆ tx_max_coalesce_frames
Configures the number of transmitted frames before the NIC
generates transmit interrupt. The valid range is from 0 to 100 and the
default is 40. This parameter and tx_coalesce_ticks cannot both have
a value of 0. If both parameters have a value of 0, no transmit
completion interrupt is generated. This parameter should always be
set lower than tx_pkt_desc_cnt. This parameter is not used and is
adjusted automatically if adaptive_coalesce is set to 1.
ˆ stats_coalesce_ticks
Configures the number of 1 usec ticks between periodic statistics
block DMAs. The valid range is from 0 to 3600000000, and the default
is 1000000 (1 sec.). Set this parameter to a value of 0 to disable
statistics updates. This parameter is not used and is set to default if
rx_adaptive_coalesce is set to 1.
ˆ enable_wol
Enables or disables magic packet Wake-On-LAN when the system is
shutdown. Note that not all systems support Wake-On-LAN. Choose
from the following selections:
– 0 magic packet Wake-On-LAN disabled (default)
– 1 magic packet Wake-On-LAN enabled
