Hello,
As we are “stuck” with kernel 5.10 for the time being and a custom recompile is hard to maintain, how can we get the most used wifi drivers included/backported?
In the previous JetPack we had those realtek drivers included in the nvidia-l4t-kernel
package:
jetson@jetson:~$ ls /lib/modules/4.9.253-tegra/kernel/drivers/net/wireless/realtek/
rtl818x rtl8812au rtl8814au rtl8821au rtl8821cu rtl8822bu rtl8822ce rtl8xxxu rtlwifi
Now we only have those:
jetson@jetson:~$ ls /lib/modules/5.10.104-tegra/kernel/drivers/net/wireless/realtek/
rtl818x rtl8822ce rtl8xxxu rtlwifi
More to this, we now want to use another (newer) Wifi 6E card, using the MediaTek mt7921u, which has the driver merged on mainline kernel 5.12 (USB support in 5.18 and AP mode in 5.19), so we need a backported version.
Looking online, I found that OpenWRT 22.03.x did that already for kernel 5.10, so should be rather easy to include into tegra-kernel, I see the version of mt76
driver included in JetPack is older.
How can we compile this as a module? I think this would benefit the whole community.
