Limitations
Users
are
advised
to
refer
to
the
Solarflare
net
driver
release
notes
for
details
of
all
limitations.
Per
Port
Configuration
For
initial
releases,
all
PFs
on
a
physical
port
have
the
same
expansion
ROM
configuration
where
PXE/UEFI
settings
are
stored.
This
means
that
all
PFs
will
PXE
boot
or
none
will
attempt
to
PXE
boot.
Users
should
ensure
that
a
DHCP
server
responds
to
the
first
MAC
address.
The
PF
(pf
‐
count)
configuration
is
a
global
setting
and
applies
to
all
physical
ports
on
an
adapter.
It
is
not
currently
possible
to
configure
ports
individually.
PTP
PTP
can
only
run
on
the
primary
physical
function
of
each
physical
port
and
is
not
supported
on
VF
interfaces.
