Reload OSX driver (kext)

The driver is located at

/System/Library/Extensions/IONetworkingFamily.kext/Contents/PlugIns/AppleRTL815X*.kext
/Library/Extensions/AppleRTL815X*.kext

Here are the namespaces:

com.realtek.driver.AppleRTL815XEthernet
com.realtek.driver.AppleRTL815XComposite


See http://osxdaily.com/2015/06/24/load-unload-kernel-extensions-mac-os-x/
With normal operation with only the network cable plugged in, I only see com.realtek.driver.AppleRTL815XEthernet loaded.
# Unload
sudo kextunload /Library/Extensions/AppleRTL815XEthernet109.kext
sudo kextunload /Library/Extensions/AppleRTL815XComposite109.kext

# Load
sudo kextload /Library/Extensions/AppleRTL815XEthernet109.kext
sudo kextload /Library/Extensions/AppleRTL815XComposite109.kext

# Find if loaded
kextstat | grep com.realtek.driver.AppleRTL815XEthernet
kextstat | grep com.realtek.driver.AppleRTL815XComposite


Perhaps clear the Kernel cache
sudo rm -rf /System/Library/Caches/com.apple.kext.caches
