This source code is based on realtek official source, VMware-ESXI-67U3-ODP and VMware-TOOLS-10.2.0-ODP.

Just do these steps:

• Prepare the building environment, I did it on CentOS 7

• Log in with root, make a folder name 'build' on /, make folder toolchain and vsphere in /build.

• Copy and extract gcc-4.8.0, binutils-2.22, glibc-2.3.4-2.41 to /build/toolchain/src

• Compile the toolchain, dest path is /build/toolchain/lin64

• Extract and copy vmkdrivers-gpl from 67U3-ODP to /build/vsphere

• Copy build-r8125.sh to /build/vsphere/vmkdrivers-gpl/

• Copy r8125 folder to /build/vsphere/vmkdrivers-gpl/vmkdrivers/src_9/drivers/net

• Run build-r8125.sh
