ev_rx_recovery
Not
supported.
ev_rx_frm_trunc
Number
of
packets
truncated
because
an
internal
FIFO
is
full.
As
a
packet
is
received
it
is
fed
by
the
MAC
into
a
128K
FIFO.
If
for
any
reason
the
PCI
interface
cannot
keep
pace
and
is
unable
to
empty
the
FIFO
at
a
sufficient
rate,
the
MAC
will
be
unable
to
feed
more
of
the
packet
to
the
FIFO.
In
this
event
the
MAC
will
truncate
the
packet
marking
it
as
such,
and
discard
the
remainder.
The
driver
on
seeing
a
'partial'
packet
which
has
been
truncated
will
discard
it.
ev_rx_tobe_disc
Number
of
packets
marked
by
the

the
following:

unicast
address
and
unicast
promiscuous
mode
is
not
enabled
•
packet
is
a
pause

•

length
discrepancy
•
internal
