6.4.4. IP Tool

The IP Tool is used to configure transmit/receive secure associations and channels. It configures the IEEE Std 802.1AE (MAC security) keys for a particular MACsec type interface.

The Linux MACsec driver and IP Tool uses rtnetlink and genetlink APIs to handle the input commands. Rtnetlink creates and sets up the net device whereas the genetlink APIs are used to set up transmit and receive secure associations on a MACsec device.

The MACsec IP driver provides read/write APIs to configure the CSR region of the MACsec HW FPGA.
