Identify Intel i225 or i226

Since the Intel i225 is approaching end-of-life (EOL), we have transitioned to the i226. You can use lspci to check which module is being used in the NRU-220S.

Because of JetPack 5.1.1 officially released driver doesn't support the i226, so we need to replace the driver in JetPack 5.1.1

Please verify that the driver is correct using with md5sum.

#check device ID
lspci -n | grep 8086 

#check driver md5sum at jetpack 5.1.1
md5sum /lib/modules/5.10.104-tegra/kernel/drivers/net/ethernet/intel/igc/igc.ko

i225

i226

Update igc.ko Jetpack 5.1.1

If you want to replace the Jetpack 5.1.1 igc.ko driver yourself, you can download the patch from the Neousys NAS
