|

* 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.
