-* Calxeda SATA Controller
-
-SATA nodes are defined to describe on-chip Serial ATA controllers.
-Each SATA controller should have its own node.
-
-Required properties:
-- compatible : compatible list, contains "calxeda,hb-ahci"
-- interrupts : <interrupt mapping for SATA IRQ>
-- reg : <registers mapping>
-
-Example:
- sata@ffe08000 {
- compatible = "calxeda,hb-ahci";
- reg = <0xffe08000 0x1000>;
- interrupts = <115>;
- };
-
Required properties:
- compatible : "fsl,sgtl5000".
+- reg : the I2C address of the device
+
Example:
codec: sgtl5000@0a {
(if tcp_adv_win_scale > 0) or bytes-bytes/2^(-tcp_adv_win_scale),
if it is <= 0.
Possible values are [-31, 31], inclusive.
- Default: 2
+ Default: 1
tcp_allowed_congestion_control - STRING
Show/set the congestion control choices available to non-privileged
net.core.rmem_max. Calling setsockopt() with SO_RCVBUF disables
automatic tuning of that socket's receive buffer size, in which
case this value is ignored.
- Default: between 87380B and 4MB, depending on RAM size.
+ Default: between 87380B and 6MB, depending on RAM size.
tcp_sack - BOOLEAN
Enable select acknowledgments (SACKS).
