6.4.3. Linux MACsec Driver Kernel Module
The Linux MACsec Driver acts as communicating medium between userspace applications. For example, IP Tool or WPA supplicant and MACsec IP + McDMA driver.
It exposes Netlink and RtnlLink interface for interaction with the IP Tool and uses macsec_ops() functionality to interact with the IP driver.
The Linux MACsec driver is responsible for creating the macsec0 interface over a parent interface mentioned in the IP tool command line. It uses the created interface to configure or get the Tx/Rx secure association details by calling respective macsec_ops().
