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 transmit and receive Jumbo Frames.
Xframe adapters support Jumbo Frames up to 9600 bytes.
For Jumbo frames, the driver will try to allocate physically contiguous buffers.
Failures to do so may degrade the performance.
To resolve such problems, please visit

where additional information and a kernel patch can be found.
For more information on configuring this device, see
ifconfig(8).
