use_random_vf_mac
When this parameter is enabled (set to 1), all created VFs will have a random
forced MAC.
By default, this parameter is disabled (set to
0).
debug
The debug parameter sets the default message level (msglevel) on all adapters in
the system at one time.
To set the message level for a specific adapter, issue the
ethtool -s command.
RSS
Use the optional RSS parameter to specify the quantity of receive side scaling
queues. RSS= –1 disables RSS queues.
max_vfs
Use the optional parameter max_vfs to enable a specific quantity of virtual
functions. Values for max_vfs can be 1 to 64, or set max_vfs=0 (default) to
disable all virtual functions.
enable_vxlan_ofld
Use the optional parameter enable_vxlan_ofld to enable VXLAN task
offloads with TX TSO and TX CSO.
enable_default_queue_filters
Use the optional parameter enable_default_queue_filters to enable the
classification filters on the default queue. The hardware supports a total of 512
classification filters that are equally divided among the ports of an adapter. For
example, a quad-port adapter has 128 filters per port. For NPAR configuration,
filters are applied on the default queue to support traffic switching between the
partitions belonging to the same physical port.
When the quantity of filters exceeds the hardware limits, the message, Rx
filters on NetQ Rx Queue 0 exhausted appears in the vmkernel logs.
The message indicates that the hardware filter limit was reached and no further
entries can be added. You can disable filters on the default queue by setting the
enable_default_queue_filters parameter to 0, which disables traffic
switching between the partitions.
