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.

The following operands are supported:

MTU size

MTU size in bytes.

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.
