Drivers match devices when i2c_client.driver_name and the driver name are
the same; this approach is used in several other busses that don't have
device typing support in the hardware. The driver and module name should
match, so hotplug/coldplug mechanisms will modprobe the driver.
The probe function is called when an entry in the id_table name field
matches the device's name. It is passed the entry that was matched so
the driver knows which one in the table matched.

the ability to dynamically add and remove new addresses for the SCTP
associations.
1: Enable extension.
0: Disable extension.
Default: 0
addip_noauth_enable - BOOLEAN
Dynamic Address Reconfiguration (ADD-IP) requires the use of
authentication to protect the operations of adding or removing new
addresses. This requirement is mandated so that unauthorized hosts
would not be able to hijack associations. However, older
implementations may not have implemented this requirement while
allowing the ADD-IP extension. For reasons of interoperability,
we provide this variable to control the enforcement of the

with older implementations.

attempt deciding that the remote end is unreachable. If this value
is exceeded, the association is terminated.
Default: 10
max_init_retransmits - INTEGER
The maximum number of retransmissions of INIT and COOKIE-ECHO chunks
that an association will attempt before declaring the destination
unreachable and terminating.
Default: 8
path_max_retrans - INTEGER
The maximum number of retransmissions that will be attempted on a given
path. Once this threshold is exceeded, the path is considered
unreachable, and new traffic will use a different path when the
association is multihomed.

rto_initial - INTEGER

in calculating round trip times. This is the initial time interval
for retransmissions.

is the largest time interval that can elapse between retransmissions.

is the smallest time interval the can elapse between retransmissions.

Determines if the receive buffer is attributed to the socket or to
association. SCTP supports the capability to create multiple
associations on a single socket. When using this capability, it is
possible that a single stalled association that's buffering a lot
of data may block other associations from delivering their data by
consuming all of the receive buffer space. To work around this,
the rcvbuf_policy could be set to attribute the receiver buffer space
to each association instead of the socket. This prevents the described
blocking.
1: rcvbuf space is per association
0: recbuf space is per socket

sndbuf_policy - INTEGER
Similar to rcvbuf_policy above, this applies to send buffer space.
1: Send buffer is tracked per association
0: Send buffer is tracked per socket.

Number of pages allowed for queueing by all SCTP sockets.
min: Below this number of pages SCTP is not bothered about its
memory appetite. When amount of memory allocated by SCTP exceeds
this number, SCTP starts to moderate memory usage.
pressure: This value was introduced to follow format of tcp_mem.
max: Number of pages allowed for queueing by all SCTP sockets.
Default is calculated at boot time from amount of available memory.
