config NET_ROUTE
bool "Routing table support"

Build in support for a routing table. See include/net/route.h
if NET_ROUTE

prompt "IPv4 routing table"
default ROUTE_IPv4_RAMROUTE
depends on NET_IPv4
config ROUTE_IPv4_RAMROUTE
bool "In-memory"
---help---
Select to used a IPv4 routing table RAM.
config ROUTE_IPv4_ROMROUTE
bool "Read-only"
---help---
Select to used a fixed read-only IPv4 routing table in FLASH or ROM.
In this case, the board-specific logic must provide a routing table
of the form of a simple array:
FAR const struct net_route_ipv4_s g_ipv4_routes[];
const unsigned int g_ipv4_nroutes;
NOTE: The read-only variable g_ipv4_nroutes must be set to the
actual number of valid entries in the array.
config ROUTE_IPv4_FILEROUTE
bool "File"
---help---
Select to used a IPv4 routing table in a file in a mounted file system.
endchoice # IPv4 routing table
config ROUTE_MAX_IPv4_RAMROUTES
int "Preallocated IPv4 routing table entries"
default 4
depends on ROUTE_IPv4_RAMROUTE
---help---
The number of preallocated of the IPv4 routing table entries. This
eliminates dynamica memory allocations, but limits the maximum size
of the in-memory routing table to this number.
config ROUTE_IPv4_CACHEROUTE
bool "In-memory IPv4 cache"
default n
depends on ROUTE_IPv4_FILEROUTE
---help---
Accessing a routing table on a file system before each packet is sent
can harm performance. This option will cache a few of the most
frequently used routing table entries in memory to reduce performance
issues.
config ROUTE_MAX_IPv4_CACHEROUTES
int "IPv4 cache size"
default 4
depends on ROUTE_IPv4_CACHEROUTE
---help---
This determines the maxium number of routes that can be cached in
memory.

config ROUTE_IPv6_RAMROUTE
bool "In-memory"
---help---
Select to use a IPv6 routing table RAM.
config ROUTE_IPv6_ROMROUTE
bool "Read-only"
---help---
Select to use a fixed read-only IPv6 routing table in FLASH or ROM.
In this case, the board-specific logic must provide a routing table
of the form of simply array:
FAR const struct net_route_ipv6_s g_ipv6_routes[];

NOTE: The read-only variable g_ipv6_nroutes must be set to the

config ROUTE_MAX_IPv6_RAMROUTES
int "Preallocated IPv6 routing table entries"
default 4
depends on ROUTE_IPv6_RAMROUTE
---help---
The number of preallocated of the IPv6 routing table entries. This

of the in-memory routing table to this number.

table will be accessed. This is a string and should not include
any traling '/'.
