Setting Values for Optional Properties

83840-546-00 N
num_vfs
Use the num_vfs parameter to active SR-IOV. For example:
modprobe bnx2x num_vfs=<num of VFs, 1..64>
The actual number of VFs are derived from this parameter, as well as the VF
maximum value configured by CCM.
autogreen
The
autogreen
parameter forces the specific AutoGrEEEN behavior.
AutoGrEEEn is a proprietary, pre-IEEE standard Energy Efficient Ethernet (EEE)
mode supported by some 1000BASE-T and 10GBASE-T RJ45 interfaced
switches.
By default, the driver uses the NVRAM configuration settings per port. When this
module parameter is set, it can override the NVRAM configuration settings to
force AutoGrEEEN to either the active (
1
) or inactive (
2
) state. The default value
of
0
sets the port to use the NVRAM settings.
native_eee
The
native_eee
parameter can force specific IEEE 802.3az Energy Efficient
Ethernet (EEE) behavior, which is supported on some 1000BASE-T and
10GBASE-T RJ45 interfaced switches.
By default, the driver uses the NVRAM configuration settings per port. If this
parameter is set, it can force EEE to be enabled, and the value will be used as the
idle time (
1–FFFFFh
or
1,048,575
) required before entering transmit LPI.
Set
native_eee
to
-1
to forcefully disable EEE. Set
native_eee
to
0
(default)
to use the NVRAM settings.
eee
The
eee
parameter sets the EEE transmit low power idle (LPI) mode timer. A
value of
0
uses the NVRAM settings. A value of
1
disables the timer.
(
0
=NVRAM settings,
1
=force disabled)
tx_switching
The
tx_switching
parameter sets the L2 Ethernet send direction to test each
transmitted packet. If the packet is intended for the transmitting NIC port, it is
hair-pin looped back by the adapter.
This parameter is relevant only in multifunction (NPAR) mode, especially in
virtualized environments.
