Description
1 - 64 Default value: 32
Number of the transmit descriptors per transmit queue. The actual
value is rounded up to the next multiple of 8. Allowed values:
64 to 4096 (default = 1024)
Number of the transmit descriptors per receive queue. The actual
value is rounded up to the next multiple of 8. Allowed values:
64 to 4096 (default = 1024)
The interval of receive interrupts is defined in 2 usec units enabling
interval range from zero to 8160 usec (0xFF0). Setting the rx_itr to
zero enables immediate interrupt. Allowed values:
0 to 4080 (default = 25)
The interval of transmit interrupts is defined in 2 usec units enabling
interval range from zero to 8160 usec (0xFF0). Setting the tx_itr to
zero enables immediate interrupt. Allowed values:
0 to 4080 (default = 25)
Maximum number of packet to receive per interrupt. Allowed values:
16 to 4096 (default = 1024)
Packet size to determine bcopy or not during receive. Allowed
values:
0 to 9216 (default = 128)
Packet size to determine bcopy or not during transmit. Allowed
values: 0 ~ 9216, 128 by default
0 to 9216 (default = 128)
