28# Driver.conf file for Netxen 10-Gigabit Ethernet devices
29#
30# All the properties below can be set globally (i.e. for all instances
31# of ntxn), or on a per-instance basis.  See driver.conf(5) for details
32# of the syntax of global and per-instance properties.
33#
34# Properties specified in this file take effect when the driver is first
35# loaded, typically just after system boot.  Changes to the file will
36# therefore not take effect until the next reboot, but will be permanent
37# thereafter.
38#
39# Some of the driver's parameters can also be changed using ndd(8).
40# Changes made with ndd apply only to a specific instance (e.g. ntxn0).
41# They take effect immediately, but are lost if the driver is unloaded.

45# The properties below represents the number of receive and send descriptors
46# used. Default values alongwith min/max/restrictions are listed.
47#
48# rx_ring_size = 8192;		# min 64, max 32768, must be power-of-2.
49#				# default on 32 bit systems is 4096.

56# The properties below represents the bcopy threshold for Transmit and
57# Receive Frame size. Higher than this threshold gets Mapped.

64# The properties below represents the maximum mtu supported by ntxn device.
65# Use this to enable jumbo frame support. Max mtu supported on P2 is 8000
66# bytes, on P3 is 9000.

72# The property below dictates whether the driver emits informational
73# messages at card initialization time (useful for debugging). Can be
