The newer adapters are only supported with up to 9K (9014 bytes) packet sizes. Some of the older, but still available, PCI-x adapters allow setting 16K (16128 bytes) packet sizes.
These are the available copper gigabit adapters that have the 16K packet support in the driver:
- Intel(R) PRO/1000 MT Server Adapter
- Intel(R) PRO/1000 MT Dual Port Server Adapter
- Intel(R) PRO/1000 GT Quad Port Server Adapter
- Intel(R) PRO/1000 GT Desktop Adapter

The Linux driver for the Intel® 10 Gigabit AT2 Server Adapter is capable of a maximum MTU setting for Jumbo Frames of 16110 bytes, which coincides with the maximum Jumbo Frames size of 16128. This adapter is capable of 1000BASE-T as well as 10GBASE-T, so you could use it in place of a gigabit adapter to get larger frame size support. However, the Windows driver has the 9014 byte MTU limit.
