rx_eth_crc_err
Number
of
packets
received
where
the
CRC
did
not
match
the
internally
generated
CRC
value.
This
is
the
total
of
all
receive
channels
receiving
CRC
errors.
rx_mcast_mismatch
Number
of
unsolicited
multicast
packets
received.
Unwanted
multicast
packets
can
be
received
because
a
connected
switch
simply
broadcasts
all
packets
to
all
endpoints
or
because
the
connected
switch
is
not
able
or
not
configured
for
IGMP
snooping
‐
a
process
from
which
it
learns
which
endpoints
are
interested
in
which
multicast
streams.
rx_frm_trunc
Number
of
frames
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
frame
‐
marking
it
as
such
and
discard
the
remainder.
The
driver
on
seeing
a
'partial'
packet
which
has
been
truncated
will
discard
it.
rx_merge_events
Number
of
RX
completion
events
where
more
than
one
RX
descriptor
was
completed.
rx_merge_packets
Number
of
packets
delivered
to
the
host
through
merge
events.
tx
‐
0.tx_packets
Per
TX
queue
transmitted
packets.
tx_1.tx_packets
Per
TX
queue
transmitted
packets.
rx_0.rx_packets
Per
RX
queue
received
packets.
rx_1.rx_packets
Per
RX
queue
received
packets.
