System
Requirements
Refer
to
for
supported
Linux
Distributions.
NOTE:
Many
Linux
distributions
include
a
version
of
the
Solarflare
network
adapter
driver
that
is
taken
from
the
upstream
kernel.
This
driver
might
be
out
of
date,
and
might
not
support
the
latest
Solarflare
adapters
and
features.
To
update
the
supplied
driver,

adapters
support
the
hardware
timestamping
of
all
received
packets
‐
including
PTP
packets.
The
Linux
kernel
must
support
the
SO_TIMESTAMPING
socket
option
(2.6.30+)
to
allow
the
driver
to
support
hardware
packet
timestamping.
Therefore
hardware
packet
timestamping
is
not
available
in
RHEL
5.
Jumbo

Support
for
MTUs
(Maximum
Transmission
Units)
from
1500
bytes
to
9216
bytes.
