rx_priority_pause_frames The number of Ethernet priority pause frames (priority flow control)
received per port.
tx_priority_pause_frames The number of Ethernet priority pause frames transmitted per port.
pmem_fifo_overflow_drop Received packets dropped when an internal FIFO going into main
packet buffer tank (PMEM) overflows.
jabber_events The number jabber packets received. Jabber packets are packets
that are longer than the maximum size Ethernet frames and that
have bad CRC.
rx_drops_no_pbuf Packets dropped due to lack of available HW packet buffers used to
temporarily hold the received packets.
rx_drops_no_erx_descr Received packets dropped due to the input receive buffer descriptor
FIFO overflowing.
rx_drops_no_tpre_descr Packets dropped because the internal FIFO to the offloaded TCP
receive processing block is full. This could happen only for offloaded
iSCSI or FCoE traffic.
rx_drops_too_many_frags Received packets dropped when they need more than 8 receive
buffers. This counter will always be 0.
forwarded_packets The number of packets generated by ASIC internally. These packets
are not handed to the host. This counter is shared across ports and
all functions (NIC/FCoE/iSCSI).
rx_drops_mtu Received packets dropped when the frame length is more than 9018
bytes.
eth_red_drops Received packets dropped due to ASIC’s Random Early Drop policy.
on_die_temperature Die temperature on the ASIC.
link_down_reason The reason ASIC signaled the link status as down. The various values
are:
0 – Link down due to reasons other than those listed here.
1 – Link down caused by Dynamic Control channel protocol.
3 - Link down triggered by Virtual NIC configuration (for example:
zero bandwidth assigned to a VNIC).
4 – Link down caused by Ethernet Pause frame flooding.
5 – Link down due to physical thermal temperature going up.
Table E-2 Transmit/Receive Queue Statistics
Statistic Description
rxq<x>:rx_bytes The number bytes received by the driver.
rxq<x>:rx_pkts The number of packets received by the driver.
rxq<x>:rx_compl The number of receive completions signaled to the driver by ASIC.
rxq<x>:rx_mcast_pkts The number of multicast packets received by the driver.
