Enable PTP Hardware Timestamp on 10GbE of NRU-230V-AWP

It seems that the built-in AQC113CS driver does not enable the hardware 1588 feature. Inspired by an article from the NVIDIA Developer Forum, we found that hardware PTP could be enabled by updating the AQC113CS driver to the devel version.

For JetPack 5.1.1 User

If you are using JetPack 5.1.1, please follow these steps to ensure the kernel sources are installed correctly.

# Install openssl 
sudo apt-get update
sudo apt-get install -y libssl-dev

# Download the kernel source to ~/Desktop
## Ref: https://developer.nvidia.com/embedded/jetson-linux-r3531
JP=/home/$USER/Desktop/JP511
DriverPackageBSPSources=https://developer.nvidia.com/downloads/embedded/l4t/r35_release_v3.1/sources/public_sources.tbz2/

mkdir -p $JP
cd $JP

wget -O driverSource.tar.gz $DriverPackageBSPSources

# Decompress Kernel Source
cd $JP
tar xvjf driverSource.tar.gz

cd $JP/Linux_for_Tegra/source/public
mkdir -p $JP/Linux_for_Tegra/sources
tar xvf kernel_src.tbz2 -C $JP/Linux_for_Tegra/sources

# Copy downloaded kernel sources to /usr/src/linux-headers 
cd $JP/Linux_for_Tegra/sources/kernel
sudo cp -pr * /usr/src/linux-headers-5.10.104-tegra-ubuntu20.04_aarch64/

# Test the kernel compile environment for kernel modules
cd /usr/src/linux-headers-5.10.104-tegra-ubuntu20.04_aarch64/kernel-5.10
sudo make modules_prepare

Install AQtion Devel Branch

cd ~/Desktop
git clone https://github.com/ctu-vras/AQtion/

cd AQtion/
sudo rmmod atlantic
sudo make
sudo make install 
sudo make load

# The the driver will be installed on
# /lib/modules/5.10.104-tegra/updates/drivers/net/ethernet/aquantia/atlantic/atlantic.ko

sudo reboot
