Configure
the
firmware
variant
to
use.
This
is
for
SFN7000
and
SFN8000
series
adapters
only:
•
the
SFN7002F
adapter
is
factory
set
to
full
‐
feature
•
all
other
adapters
are
factory
set
to
auto.
Default
value
=
auto
‐
means
the
driver
will
select
a
variant
that
meets
its
needs:
•
the
VMware
driver
always
uses
full
‐
feature
•
otherwise,
ultra
‐
low
‐
latency
is
used.
The
ultra
‐
low
‐
latency
variant
produces
best
latency
without
support
for
TX
VLAN
insertion
or
RX
VLAN
stripping
(not
currently
used
features).
It
is
recommended
that
Onload
customers
use
the
ultra
‐
low
‐
latency
variant.
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
when
using
Onload
or
when
using
bonded
interfaces.
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.
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.
