rdt_setmtu(1M) System Administration Commands rdt_setmtu(1M)NAME
rdt_setmtu - set the MTU size in RSMRDT driver
SYNOPSIS
/usr/cluster/bin/rdt_setmtu [MTU size]
DESCRIPTION
The rdt_setmtu command takes number of bytes as new MTU size and sets the global MTU size in RSMRDT driver. The RSMRDT driver uses the new
MTU size for all the new instantiations of RSM connections. The existing RSM connections continue to use the old MTU size value. The MTU
size should be a multiple of 64(0x40) bytes otherwise rdt_setmtu does not set the MTU size in RSMRDT driver and returns an error. The
rdt_setmtu when running without any argument, displays the MTU size of RSMRDT driver.
You can use this command only in the global zone.
OPERANDS
The following operands are supported:
MTU size MTU size in bytes.
EXIT STATUS
The following exit values are returned:
0 Successful completion.
1 An error occurred while setting MTU size.
This utility writes an error message to stderr when it exits with non-zero status.

IXG(4) BSD Kernel Interfaces Manual IXG(4)NAME
ixg -- Intel(R) 10Gb Ethernet driver
SYNOPSIS
ixg* at pci? dev ? function ?
DESCRIPTION
The ixg driver provides support for PCI 10Gb Ethernet adapters based on the Intel(R) 82598EB and 82599 10 GbE Controllers. The driver sup-
ports Jumbo Frames, TCP Segmentation Offload (TSO).
For questions related to hardware requirements, refer to the documentation supplied with your Intel 10GbE adapter. All hardware requirements
listed apply to use with NetBSD.
Support for Jumbo Frames is provided via the interface MTU setting. Selecting an MTU larger than 1500 bytes with the ifconfig(8) utility
configures the adapter to receive and transmit Jumbo Frames. On NetBSD, the maximum MTU size for Jumbo Frames is 9000 bytes.
This driver version supports VLANs. For information on enabling VLANs, see ifconfig(8).
HARDWARE
The ixg driver supports the following cards:
o Intel(R) 10 Gigabit XF SR/AF Dual Port Server Adapter
o Intel(R) 10 Gigabit XF SR/LR Server Adapter
o Intel(R) 82598EB 10 Gigabit AF Network Connection
o Intel(R) 82598EB 10 Gigabit AT CX4 Network Connection
DIAGNOSTICS
ixg%d: Unable to allocate bus resource: memory A fatal initialization error has occurred.
ixg%d: Unable to allocate bus resource: interrupt A fatal initialization error has occurred.
ixg%d: watchdog timeout -- resetting The device has stopped responding to the network, or there is a problem with the network connection
(cable).
SUPPORT

SEE ALSO arp(4), netintro(4), vlan(4), ifconfig(8)HISTORY
The ixg device driver comes from FreeBSD, where it is called ixgbe(4). It first appeared in NetBSD 6.0.
AUTHORS
The ixg driver was written by Intel Corporation <freebsdnic@mailbox.intel.com>. It was imported from FreeBSD into NetBSD by
David Young <dyoung@NetBSD.org>.
BUGS
The hardware supports a maximum MTU of 16114 bytes, but the NetBSD port of the driver supports only 9000 bytes.
The hardware supports Message-Signalled Interrupts (MSI and MSI-X) and Receive-Side Scaling (RSS), however, these features are not enabled in
the NetBSD driver at this time.
