Mock implementation of NETMAP routines is located in ena_netmap.c/.h files. All code is protected under the DEV_NETMAP macro. Makefile was updated with files and flag. As ENA driver provide own implementations of (un)likely it must be undefined before including NETMAP headers. ena_netmap_attach function is called on the end of NIC attach. It fills structure with NIC configuration and callbacks. Then provides it to netmap_attach. Similarly netmap_detach is called during ena_detach. Three callbacks are used. nm_register is implemented by ena_netmap_reg. It is called when user space application open or close NIC in NETMAP mode. Current action is recognized based on onoff parameter: true means on and false off. As NICs rings need to be reconfigured ena_down and ena_up are reused. When user space application wants to receive new packets from NIC nm_rxsync is called, and when there are new packets ready for Tx nm_txsync is called.
