Setting Values for Optional Properties
47 BC0054508-00 M
tx_switching
The tx_switching parameter sets the L2 Ethernet send direction to test each
transmitted packet. If the packet is intended for the transmitting NIC port, it is
hair-pin looped back by the adapter.
This parameter is relevant only in multifunction (NPAR) mode, especially in
virtualized environments.
full_promiscous
The full_promiscous parameter extends the existing promiscuous mode
settings to accept all unmatched unicast packets on the interface.
By default, this parameter is disabled (set to
0).
fairness_threshold
The fairness_threshold parameter enables firmware thresholds for physical
functions (PFs) in multifunction (MF) mode where more than one PF is configured
on a single, physical Ethernet port.
By default, this parameter is disabled (set to
0).
poll
This optional debug parameter is used for timer-based polling.
mrrs
The mrrs optional debug parameter overrides the maximum read request size
(MRRS) of the hardware. Valid values are in the range of 0–3.
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.
