Configuring
the
Solarflare
Adapter
The
drivers
will
be
loaded
as
part
of
the
as
part
of
the
installation.
However
the
adapter
will
not
be
configured
(adding
IP
address
and
netmask).
Each
Solarflare
network
adapter
interface
will
be
named
sfxge<n>
where
<n>
is
a
unique
identifier.
There
will
be
one
interface
per
physical
port
on
the
Solarflare
adapter.
To
configure
the
interface
and
bring
it
up
to
allow
data
to
pass,
enter
the
following:
ifconfig
sfxge<n>
inet
<IPv4
address>
netmask
<netmask>
up
This
configures
the
interface
and
initializes
it
with
the
up
command.
NOTE:
This
method
of
configuring
is
temporary.
If
you
reboot
your
computer
the
settings
will
be
lost.
To
make
these
settings
permanent,
create
entries
in
the
configuration
file
as
described
below.
Using
IPv6
To
configure
using
IPv6,
create
an
IPv6
interface
sfxge<n>
interface
with
a
link
local
IPv6
address
by
entering:
ifconfig
sfxge<n>
inet6
<IPv6
address>
prefixlen
<IPv6
prefix
length>
This
uses
automatic
link
‐
local
address
configuration,
which
is
enabled
by
default
in
FreeBSD.
It
will
give
an
IPv6
interface
name
of
sfxge<n>:1
Using

To
use
this
option,
add:
ifconfig_sfxge<n>="inet
