.RE
.TP
.B \-i \-\-driver
Queries the specified network device for associated driver information.
.TP
.B \-d \-\-register\-dump
Retrieves and prints a register dump for the specified network device.
The register format for some devices is known and decoded others
are printed in hex.
When
.I raw
is enabled, then ethtool dumps the raw register data to stdout.
If
.I file
is specified, then use contents of previous raw register dump, rather
than reading from the device.
.TP
.B \-e \-\-eeprom\-dump
Retrieves and prints an EEPROM dump for the specified network device.
When raw is enabled, then it dumps the raw EEPROM data to stdout. The
length and offset parameters allow dumping certain portions of the EEPROM.
Default is to dump the entire EEPROM.
.RS 4
.TP
.BI raw \ on|off
.TP
.BI offset \ N
.TP
.BI length \ N
.RE
.TP
.B \-E \-\-change\-eeprom
If value is specified, changes EEPROM byte for the specified network device.
offset and value specify which byte and it's new value. If value is not
specified, stdin is read and written to the EEPROM. The length and offset
parameters allow writing to certain portions of the EEPROM.
Because of the persistent nature of writing to the EEPROM, a device-specific
magic key must be specified to prevent the accidental writing to the EEPROM.
.TP
.B \-k \-\-show\-features \-\-show\-offload
Queries the specified network device for the state of protocol
offload and other features.
.TP
.B \-K \-\-features \-\-offload

network device. The following feature names are built-in and others
may be defined by the kernel.

Specifies whether Rx ntuple filters and actions should be enabled
.TP
.A2 rxhash on off
Specifies whether receive hashing offload should be enabled
.RE

Initiates adapter-specific action intended to enable an operator to
easily identify the adapter by sight. Typically this involves
blinking one or more LEDs on the specific network port.

.RE
.TP
.B \-P \-\-show\-permaddr

auto-negotiation is enabled.
.TP
.B \-S \-\-statistics
Queries the specified network device for standard (IEEE, IETF, etc.), or NIC-
and driver-specific statistics. NIC- and driver-specific statistics are
requested when no group of statistics is specified.
NIC- and driver-specific statistics and standard statistics are independent,
devices may implement either, both or none. There is little commonality between
naming of NIC- and driver-specific statistics across vendors.
.RS 4

All following options only apply if
.B \-s
was specified.
.RS 4
.TP
.BI speed \ N
Set speed in Mb/s.

with just the device name as an argument will show you the supported device speeds.
.TP
.BI lanes \ N
Set number of lanes.
.TP
.A2 duplex half full
Sets full or half duplex mode.
.TP
.A4 port tp aui bnc mii fibre da
Selects device port.
.TP
.BR master-slave \ \*(MS
Configure MASTER/SLAVE role of the PHY. When the PHY is configured as MASTER,
the PMA Transmit function shall source TX_TCLK from a local clock source. When
configured as SLAVE, the PMA Transmit function shall source TX_TCLK from the
clock recovered from data stream provided by MASTER. Not all devices support this.

.TE
.TP
.A3 mdix auto on off
Selects MDI-X mode for port. May be used to override the automatic
detection feature of most adapters. An argument of \fBauto\fR means
automatic detection of MDI status, \fBon\fR forces MDI-X (crossover)
mode, while \fBoff\fR means MDI (straight through) mode. The driver
should guarantee that this command takes effect immediately, and if
necessary may reset the link to cause the change to take effect.
.TP
.A2 autoneg on off
Specifies whether autonegotiation should be enabled. Autonegotiation
is enabled by default, but in some network devices may have trouble
with it, so you can disable it if really necessary.
.TP
.BI advertise \ N
Sets the speed and duplex advertised by autonegotiation. The argument is
a hexadecimal value using one or a combination of the following values:
