Attempting to create a host-interface with an invalid af_packet name
causes a crash, as we attempt to read the contents of a null ptr.

Normally af_packet sets next0 = next_index on each cycle. It works for the most cases.
But if vlib_validate_buffer_enqueue_x1() changes the next_index (from NEXT_ETHERNET to NEXT_DROP for example)
then the following next0 will have the wrong value, and the correct packet will be dropped.
AF_PACKET_IF_MODE_IP handles this case, but AF_PACKET_IF_MODE_ETHERNET doesn't.

Type: improvement
This patch implements support to check the host interface offload
capabilities.
NOTE: this check is only done once when interface is being created.
Any changes to the cap of host interface after that will not reflect
changes to af_packet interface in VPP.

af_packet does not process data until the interface is UP. If after interface creation, but before it is UP, the host interfaces are flooded, then blocking case may occur - VPP interface will never be able to process the data.
If the EDGE_TRIGGERED flag is set, the event will not arrive, because nothing new is happening anymore (probably because the queue is already full).
Therefore, we need to use LEVEL_TRIGGERED (default value), which indicates that there is still unprocessed data (accumulated after interface creation, but before it was UP).

Type: fix
In vpp, file descriptor handler closes the fd upon error
if there is no error handling function is registered.
This patch fixes the issue for af_packet interface by
registering the error handling function.
Errors will also be gracefully logged.
