This patch introduces the netdev_macsec structure. It will be used in the kernel to exchange information between the common MACsec implementation (macsec.c) and the MACsec hardware offloading implementations. This structure contains a command (struct netdev_macsec_command) and pointers to MACsec specific structures which contain the actual MACsec configuration.
