ˆrx_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.

ˆtx_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.

ˆtx_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.

ˆstats_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.

ˆenable_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
