JETSON XAVIER NX intel AC-9260 driver

Hi,
I want to use network card of AC-9260 on jetson xavier nx.But I find it can’t work. My linux kernel is 4.9.201, and i can inquier it by command of ‘lspci’. Now, I still can’t connect to the wireless network by AC-9260. Is it related to the setting of the device tree? Specific information is as follows :

nvidia@nvidia-desktop:~$ lspci

0004:01:00.0 Network controller: Intel Corporation Wireless-AC 9260 (rev 29)

Intel 9260 provide the default driver for kernel 4.14+ as default. For jetson, the kernel version 4.9 need driver backport.
You can get the right backport driver here: kernel/git/iwlwifi/backport-iwlwifi.git - Backport tree for iwlwifi

hello,
Thank you very much, I have solved the problem。
