@@ -30,16 +30,24 @@ neigh/default/gc_thresh3 - INTEGER
Maximum number of neighbor entries allowed. Increase this
when using large numbers of interfaces and when communicating
with large numbers of directly-connected peers.
+ Default: 1024
neigh/default/unres_qlen_bytes - INTEGER
The maximum number of bytes which may be used by packets
queued for each unresolved address by other network layers.
(added in linux 3.3)
+ Seting negative value is meaningless and will retrun error.
+ Default: 65536 Bytes(64KB)
neigh/default/unres_qlen - INTEGER
The maximum number of packets which may be queued for each
unresolved address by other network layers.
(deprecated in linux 3.3) : use unres_qlen_bytes instead.
+ Prior to linux 3.3, the default value is 3 which may cause
+ secluded packet loss. The current default value is calculated
+ according to default value of unres_qlen_bytes and true size of
+ packet.
+ Default: 31
mtu_expires - INTEGER
Time, in seconds, that cached PMTU information is kept.
