33 .Nd Packet-oriented transport for Non-Transparent Bridges
35 To load the driver as a module at boot, place the following line in
37 .Bd -literal -offset indent
38 ntb_transport_load="YES"
41 The following tunables are settable from the
44 .It Va hw.ntb_transport.debug_level
46 The default value is 0, higher means more verbose.

48 Configures queues allocation for consumer devices, separated by commas.
49 Each device can be configured as: "<name>[:<queues>]", where:
51 is a name of the driver which should attach the device (empty means any),
53 is a number of queues to allocate (empty means automatic),
54 The default configuration is empty string, which means single device
55 with one queue per memory window allowing any driver attachment.
60 driver attaches on top of the
62 driver to utilize its resources to create set of bidirectional queues,
63 delivering packets between the systems.
64 The primary purpose of this is to be used by
66 network interface, but other consumers may also be developed using KPI.
74 driver was developed by Intel and originally written by

76 Later improvements were done by
