L4T Kernel update, driver for new chip

Hello. Our company designs hardware with a jetson-nano module and a custom board. Our board contains the chip lan743x, connected to the PCI-E host of Jetson-Nano.
Support for this chip in Linux starts at kernel 4.18 and more. We still have not succeeded in porting the driver to the 4.9 kernel included in the L4T.
Question: how soon will the Linux kernel update in L4T for jetson nano, is this at least in plans? Maybe you can advise something else?

Hi deadfis45,

To update the new Linux kernel is under planning, but no clear schedule yet, at least will not happened in this 1H/2020.
