- Promiscuous mode
- Port hardware statistics
- Jumbo frames
+- Scatter-Gather IO support
- Link state information
+- MAC/VLAN filtering
+- MTU update
- SR-IOV VF
- Multiple queues for TX
- Lock-free Tx queue
as it is the most performance effective way for packet allocation and Tx buffer
recycling on OCTEON TX SoC platform.
-CRC striping
-~~~~~~~~~~~~
+CRC stripping
+~~~~~~~~~~~~~
The OCTEON TX SoC family NICs strip the CRC for every packets coming into the
host interface irrespective of the offload configuration.
is fixed and cannot be changed. So, even when the ``rxmode.max_rx_pkt_len``
member of ``struct rte_eth_conf`` is set to a value lower than 32k, frames
up to 32k bytes can still reach the host interface.
+
+Maximum mempool size
+~~~~~~~~~~~~~~~~~~~~
+
+The maximum mempool size supplied to Rx queue setup should be less than 128K.
+When running testpmd on OCTEON TX the application can limit the number of mbufs
+by using the option ``--total-num-mbufs=131072``.
