insecure ‐ filters=

enabled|disabled
If enabled bypass filter security on non ‐ privileged
functions. This is for SFN7000 and SFN8000 series adapters
only. This reduces security in virtualized environments. The
default is disabled. When enabled a function (PF or VF) can
insert filters not qualified by their own permanent MAC
address. This is a requirement and should be enabled when
using Onload or when using bonded interfaces. This is a
global option and applies to all ports on the NIC.
mac ‐
spoofing=default|enabled|disabled
If enabled, non ‐ privileged functions can create unicast
filters for MAC addresses that are not associated with them.
This is for SFN7000 and SFN8000 series adapters only.
The default is disabled.
Changes to this setting with
sfboot
require a cold reboot to
become effective. This is a global option and applies to all
ports on the NIC.
rx ‐ dc ‐ size=8|16|32|64 Specifies the size of the descriptor cache for each receive
queue. This is for SFN7000 and SFN8000 series adapters
only. The default is:
•
16
if the
port ‐ mode
supports the maximum number of
connectors for the adapter
•
32
if the
port ‐ mode
supports a reduced number of
connectors.
change ‐ mac=
default|enabled|disabled
This is for SFN7000 and SFN8000 series adapters only.
Change the unicast MAC address for a non ‐ privileged
function on this port. This is a global option and applies to
all physical ports on the NIC.
tx ‐ dc ‐ size=8|16|32|64
Specifies the size of the descriptor cache for each transmit
queue. This is for SFN7000 and SFN8000 series adapters
only. The default is:
•
32
if the
port ‐ mode
supports the maximum number of
connectors for the adapter
•
64
if the
port ‐ mode
supports a reduced number of
connectors.
vi ‐ count=<vi count> Sets the total number of virtual interfaces that will be
available on the NIC.
event ‐ merge ‐ timeout=

<timeout in nanoseconds>
Specifies the timeout in nanoseconds for RX event merging.
A timeout of 0 means that event merging is disabled.
