The Gianfar Ethernet Driver
-Sysfs File description
Author: Andy Fleming <afleming@freescale.com>
Updated: 2005-07-28
-SYSFS
-
-Several of the features of the gianfar driver are controlled
-through sysfs files. These are:
-
-bd_stash:
-To stash RX Buffer Descriptors in the L2, echo 'on' or '1' to
-bd_stash, echo 'off' or '0' to disable
-
-rx_stash_len:
-To stash the first n bytes of the packet in L2, echo the number
-of bytes to buf_stash_len. echo 0 to disable.
-
-WARNING: You could really screw these up if you set them too low or high!
-fifo_threshold:
-To change the number of bytes the controller needs in the
-fifo before it starts transmission, echo the number of bytes to
-fifo_thresh. Range should be 0-511.
-
-fifo_starve:
-When the FIFO has less than this many bytes during a transmit, it
-enters starve mode, and increases the priority of TX memory
-transactions. To change, echo the number of bytes to
-fifo_starve. Range should be 0-511.
-
-fifo_starve_off:
-Once in starve mode, the FIFO remains there until it has this
-many bytes. To change, echo the number of bytes to
-fifo_starve_off. Range should be 0-511.

OVERVIEW
@@ -864,3 +866,82 @@
This is used to allocate a null RxRPC key that can be used to indicate
anonymous security for a particular domain.
+
+
+=======================
+CONFIGURABLE PARAMETERS
+=======================
+
+The RxRPC protocol driver has a number of configurable parameters that can be
+adjusted through sysctls in /proc/net/rxrpc/:
+
+ (*) req_ack_delay
+
+ The amount of time in milliseconds after receiving a packet with the
+ request-ack flag set before we honour the flag and actually send the
+ requested ack.
+
+ Usually the other side won't stop sending packets until the advertised
+ reception window is full (to a maximum of 255 packets), so delaying the
+ ACK permits several packets to be ACK'd in one go.
+
+ (*) soft_ack_delay
+
+ The amount of time in milliseconds after receiving a new packet before we
+ generate a soft-ACK to tell the sender that it doesn't need to resend.
+
+ (*) idle_ack_delay
+
+ The amount of time in milliseconds after all the packets currently in the
+ received queue have been consumed before we generate a hard-ACK to tell
+ the sender it can free its buffers, assuming no other reason occurs that
+ we would send an ACK.
+
+ (*) resend_timeout
+
+ The amount of time in milliseconds after transmitting a packet before we
+ transmit it again, assuming no ACK is received from the receiver telling
+ us they got it.
+
+ (*) max_call_lifetime
+
+ The maximum amount of time in seconds that a call may be in progress
+ before we preemptively kill it.
+
+ (*) dead_call_expiry
+
+ The amount of time in seconds before we remove a dead call from the call
+ list. Dead calls are kept around for a little while for the purpose of
+ repeating ACK and ABORT packets.
+
+ (*) connection_expiry
+
+ The amount of time in seconds after a connection was last used before we
+ remove it from the connection list. Whilst a connection is in existence,
+ it serves as a placeholder for negotiated security; when it is deleted,
+ the security must be renegotiated.
+
+ (*) transport_expiry
+
+ The amount of time in seconds after a transport was last used before we
+ remove it from the transport list. Whilst a transport is in existence, it
+ serves to anchor the peer data and keeps the connection ID counter.
+
+ (*) rxrpc_rx_window_size
+
+ The size of the receive window in packets. This is the maximum number of
+ unconsumed received packets we're willing to hold in memory for any
+ particular call.
+
+ (*) rxrpc_rx_mtu
+
+ The maximum packet MTU size that we're willing to receive in bytes. This
+ indicates to the peer whether we're willing to accept jumbo packets.
+
+ (*) rxrpc_rx_jumbo_max
+
+ The maximum number of packets that we're willing to accept in a jumbo
+ packet. Non-terminal packets in a jumbo packet must contain a four byte
+ header plus exactly 1412 bytes of data. The terminal packet must contain
+ a four byte header plus any amount of data. In any event, a jumbo packet
+ may not exceed rxrpc_rx_mtu in size.
