Recognise the new Packet Memory and RX Data Path counters.
The following counters are added:
rx_pm_{trunc,discard}_bb_overflow - burst buffer overflowed. This should not
occur if BB correctly configured.
rx_pm_{trunc,discard}_vfifo_full - not enough space in packet memory. May
indicate RX performance problems.
rx_pm_{trunc,discard}_qbb - dropped by 802.1Qbb early discard mechanism.
Since Qbb is not supported at present, this should not occur.
rx_pm_discard_mapping - 802.1p priority configured to be dropped. This should
not occur in normal operation.
rx_dp_q_disabled_packets - packet was to be delivered to a queue but queue is
disabled. May indicate misconfiguration by the driver.
rx_dp_di_dropped_packets - parser-dispatcher indicated that a packet should be
dropped.
rx_dp_streaming_packets - packet was sent to the RXDP streaming bus, ie. a
filter directed the packet to the MCPU.
rx_dp_emerg_{fetch,wait} - RX datapath had to wait for descriptors to be
loaded. Indicates performance problems but not drops.
These are only provided if the MC firmware has the
PM_AND_RXDP_COUNTERS capability. Otherwise, mask them out.
