and CONFIG_NET_DMA is enabled.
Default: 4096
+tcp_thin_linear_timeouts - BOOLEAN
+ Enable dynamic triggering of linear timeouts for thin streams.
+ If set, a check is performed upon retransmission by timeout to
+ determine if the stream is thin (less than 4 packets in flight).
+ As long as the stream is found to be thin, up to 6 linear
+ timeouts may be performed before exponential backoff mode is
+ initiated. This improves retransmission latency for
+ non-aggressive thin streams, often found to be time-dependent.
+ For more information on thin streams, see
+ Documentation/networking/tcp-thin.txt
+ Default: 0
+
+tcp_thin_dupack - BOOLEAN
+ Enable dynamic triggering of retransmissions after one dupACK
+ for thin streams. If set, a check is performed upon reception
+ of a dupACK to determine if the stream is thin (less than 4
+ packets in flight). As long as the stream is found to be thin,
+ data is retransmitted on the first received dupACK. This
+ improves retransmission latency for non-aggressive thin
+ streams, often found to be time-dependent.
+ For more information on thin streams, see
+ Documentation/networking/tcp-thin.txt
+ Default: 0
+
UDP variables:
udp_mem - vector of 3 INTEGERs: min, pressure, max
conf/{all,interface}/proxy_arp is set to TRUE,
it will be disabled otherwise
+proxy_arp_pvlan - BOOLEAN
+ Private VLAN proxy arp.
+ Basically allow proxy arp replies back to the same interface
+ (from which the ARP request/solicitation was received).
+
+ This is done to support (ethernet) switch features, like RFC
+ 3069, where the individual ports are NOT allowed to
+ communicate with each other, but they are allowed to talk to
+ the upstream router. As described in RFC 3069, it is possible
+ to allow these hosts to communicate through the upstream
+ router by proxy_arp'ing. Don't need to be used together with
+ proxy_arp.
+
+ This technology is known by different names:
+ In RFC 3069 it is called VLAN Aggregation.
+ Cisco and Allied Telesyn call it Private VLAN.
+ Hewlett-Packard call it Source-Port filtering or port-isolation.
+ Ericsson call it MAC-Forced Forwarding (RFC Draft).
+
shared_media - BOOLEAN
Send(router) or accept(host) RFC1620 shared media redirects.
Overrides ip_secure_redirects.
or hardware address changes.
arp_accept - BOOLEAN
- Define behavior when gratuitous arp replies are received:
- 0 - drop gratuitous arp frames
- 1 - accept gratuitous arp frames
+ Define behavior for gratuitous ARP frames who's IP is not
+ already present in the ARP table:
+ 0 - don't create new entries in the ARP table
+ 1 - create new entries in the ARP table
+
+ Both replies and requests type gratuitous arp will trigger the
+ ARP table to be updated, if this setting is on.
+
+ If the ARP table already contains the IP address of the
+ gratuitous arp frame, the arp table will be updated regardless
+ if this setting is on or off.
+
app_solicit - INTEGER
The maximum number of probes to send to the user space ARP daemon
Default: 5
max_addresses - INTEGER
- Number of maximum addresses per interface. 0 disables limitation.
- It is recommended not set too large value (or 0) because it would
- be too easy way to crash kernel to allow to create too much of
- autoconfigured addresses.
+ Maximum number of autoconfigured addresses per interface. Setting
+ to zero disables the limitation. It is not recommended to set this
+ value too large (or to zero) because it would be an easy way to
+ crash the kernel by allowing too many addresses to be created.
Default: 16
disable_ipv6 - BOOLEAN
