* For each "interface" (NIC, host stack, PIPE, VALE switch port) bound to
* a file descriptor, the mmap()ed region contains a (logically readonly)
* struct netmap_if pointing to struct netmap_ring's.
*
* There is one netmap_ring per physical NIC ring, plus one tx/rx ring
* pair attached to the host stack (this pair is unused for non-NIC ports).
*
* All physical/host stack ports share the same memory region,
* so that zero-copy can be implemented between them.
* VALE switch ports instead have separate memory regions.
*
* The netmap_ring is the userspace-visible replica of the NIC ring.
* Each slot has the index of a buffer (MTU-sized and residing in the
* mmapped region), its length and some flags. An extra 64-bit pointer
* is provided for user-supplied buffers in the tx path.
*
* In user space, the buffer address is computed as
* (char *)ring + buf_ofs + index * NETMAP_BUF_SIZE
*
* Added in NETMAP_API 11:
*
* + NIOCREGIF can request the allocation of extra spare buffers from
* the same memory pool. The desired number of buffers must be in
* nr_arg3. The ioctl may return fewer buffers, depending on memory
* availability. nr_arg3 will return the actual value, and, once
* mapped, nifp->ni_bufs_head will be the index of the first buffer.
*
* The buffers are linked to each other using the first uint32_t
* as the index. On close, ni_bufs_head must point to the list of
* buffers to be released.
*
* + NIOCREGIF can request space for extra rings (and buffers)
* allocated in the same memory space. The number of extra rings
* is in nr_arg1, and is advisory. This is a no-op on NICs where
* the size of the memory space is fixed.
*
* + NIOCREGIF can attach to PIPE rings sharing the same memory
* space with a parent device. The ifname indicates the parent device,
* which must already exist. Flags in nr_flags indicate if we want to
* bind the master or slave side, the index (from nr_ringid)
* is just a cookie and does not need to be sequential.
*
* + NIOCREGIF can also attach to 'monitor' rings that replicate
* the content of specific rings, also from the same memory space.
*
* Extra flags in nr_flags support the above functions.
* Application libraries may use the following naming scheme:
* netmap:foo all NIC ring pairs
* netmap:foo^ only host ring pair
* netmap:foo+ all NIC ring + host ring pairs
* netmap:foo-k the k-th NIC ring pair
* netmap:foo{k PIPE ring pair k, master side
* netmap:foo}k PIPE ring pair k, slave side
*
* Some notes about host rings:
*
* + The RX host ring is used to store those packets that the host network
* stack is trying to transmit through a NIC queue, but only if that queue
* is currently in netmap mode. Netmap will not intercept host stack mbufs
* designated to NIC queues that are not in netmap mode. As a consequence,
* registering a netmap port with netmap:foo^ is not enough to intercept
* mbufs in the RX host ring; the netmap port should be registered with
* netmap:foo*, or another registration should be done to open at least a
* NIC TX queue in netmap mode.
*
* + Netmap is not currently able to deal with intercepted trasmit mbufs which
* require offloadings like TSO, UFO, checksumming offloadings, etc. It is
* responsibility of the user to disable those offloadings (e.g. using
* ifconfig on FreeBSD or ethtool -K on Linux) for an interface that is being
* used in netmap mode. If the offloadings are not disabled, GSO and/or
* unchecksummed packets may be dropped immediately or end up in the host RX
* ring, and will be dropped as soon as the packet reaches another netmap
* adapter.

/*
* ioctl names and related fields
*
* NIOCTXSYNC, NIOCRXSYNC synchronize tx or rx queues,
* whose identity is set in NIOCREGIF through nr_ringid.
* These are non blocking and take no argument.
*
* NIOCGINFO takes a struct ifreq, the interface name is the input,
* the outputs are number of queues and number of descriptor
* for each queue (useful to set number of threads etc.).
* The info returned is only advisory and may change before
* the interface is bound to a file descriptor.
*
* NIOCREGIF takes an interface name within a struct nmre,
* and activates netmap mode on the interface (if possible).
*
* The argument to NIOCGINFO/NIOCREGIF overlays struct ifreq so we
* can pass it down to other NIC-related ioctls.
*
* The actual argument (struct nmreq) has a number of options to request
* different functions.
* The following are used in NIOCREGIF when nr_cmd == 0:
*
* nr_name (in)
* The name of the port (em0, valeXXX:YYY, etc.)
* limited to IFNAMSIZ for backward compatibility.
*
* nr_version (in/out)
* Must match NETMAP_API as used in the kernel, error otherwise.
* Always returns the desired value on output.
*
* nr_tx_slots, nr_tx_slots, nr_tx_rings, nr_rx_rings (in/out)
* On input, non-zero values may be used to reconfigure the port
* according to the requested values, but this is not guaranteed.
* On output the actual values in use are reported.
*
* nr_ringid (in)
* Indicates how rings should be bound to the file descriptors.
* If nr_flags != 0, then the low bits (in NETMAP_RING_MASK)
* are used to indicate the ring number, and nr_flags specifies
* the actual rings to bind. NETMAP_NO_TX_POLL is unaffected.
*
* NOTE: THE FOLLOWING (nr_flags == 0) IS DEPRECATED:
* If nr_flags == 0, NETMAP_HW_RING and NETMAP_SW_RING control
* the binding as follows:
* 0 (default) binds all physical rings
* NETMAP_HW_RING | ring number binds a single ring pair
* NETMAP_SW_RING binds only the host tx/rx rings
*
* NETMAP_NO_TX_POLL can be OR-ed to make select()/poll() push
* packets on tx rings only if POLLOUT is set.
* The default is to push any pending packet.
*
* NETMAP_DO_RX_POLL can be OR-ed to make select()/poll() release
* packets on rx rings also when POLLIN is NOT set.
* The default is to touch the rx ring only with POLLIN.
* Note that this is the opposite of TX because it
* reflects the common usage.
*
* NOTE: NETMAP_PRIV_MEM IS DEPRECATED, use nr_arg2 instead.
* NETMAP_PRIV_MEM is set on return for ports that do not use
* the global memory allocator.
* This information is not significant and applications
* should look at the region id in nr_arg2
*
* nr_flags is the recommended mode to indicate which rings should
* be bound to a file descriptor. Values are NR_REG_*
*
* nr_arg1 (in) The number of extra rings to be reserved.
* Especially when allocating a VALE port the system only
* allocates the amount of memory needed for the port.
* If more shared memory rings are desired (e.g. for pipes),
* the first invocation for the same basename/allocator
* should specify a suitable number. Memory cannot be
* extended after the first allocation without closing
* all ports on the same region.
*
* nr_arg2 (in/out) The identity of the memory region used.
* On input, 0 means the system decides autonomously,
* other values may try to select a specific region.
* On return the actual value is reported.
* Region '1' is the global allocator, normally shared
* by all interfaces. Other values are private regions.
* If two ports the same region zero-copy is possible.
*
* nr_arg3 (in/out) number of extra buffers to be allocated.
*
*
*
* nr_cmd (in) if non-zero indicates a special command:
* NETMAP_BDG_ATTACH and nr_name = vale*:ifname
* attaches the NIC to the switch; nr_ringid specifies
* which rings to use. Used by vale-ctl -a ...
* nr_arg1 = NETMAP_BDG_HOST also attaches the host port
* as in vale-ctl -h ...
*
* NETMAP_BDG_DETACH and nr_name = vale*:ifname
* disconnects a previously attached NIC.
* Used by vale-ctl -d ...
*
* NETMAP_BDG_LIST
* list the configuration of VALE switches.
*
* NETMAP_BDG_VNET_HDR
* Set the virtio-net header length used by the client
* of a VALE switch port.
*
* NETMAP_BDG_NEWIF
* create a persistent VALE port with name nr_name.
* Used by vale-ctl -n ...
*
* NETMAP_BDG_DELIF
* delete a persistent VALE port. Used by vale-ctl -d ...
