config NET_NOINTS |
|
bool "Not interrupt driven" |
|
default n |
|
---help--- |
|
NET_NOINT indicates that uIP not called from the interrupt level. |
|
If NET_NOINTS is defined, critical sections will be managed with semaphores; |
|
Otherwise, it assumed that uIP will be called from interrupt level handling |
|
and critical sections will be managed by enabling and disabling interrupts. |

config NET_MULTIBUFFER |
|
bool "Use multiple device-side I/O buffers" |
|
default n |
|
---help--- |
|
Traditionally, uIP has used a single buffer for all incoming and |
|
outgoing traffic. If this configuration is selected, then the |
|
driver can manage multiple I/O buffers and can, for example, |
|
be filling one input buffer while sending another output buffer. |
|
Or, as another example, the driver may support queuing of concurrent |
|
input/ouput and output transfers for better performance. |

config NET_SLIP |
|
bool "SLIP support" |
|
default n |
|
---help--- |
|
Enables building of the SLIP driver. SLIP requires |
|
at least one IP protocol selected and the following additional |
|
network settings: NET_NOINTS and NET_MULTIBUFFER. |
|
|
|
NET_BUFSIZE *must* be set to 296. Other optional configuration |
|
settings that affect the SLIP driver: NET_STATISTICS. |
|
Default: Ethernet |
|
|
|
SLIP supports point-to-point IP communications over a serial port. |
|
The default data link layer for uIP is Ethernet. If NET_SLIP is |
|
defined in the NuttX configuration file, then SLIP will be supported. |
|
The basic differences between the SLIP and Ethernet configurations is |
|
that when SLIP is selected: |
|
|
|
* The link level header (that comes before the IP header) is omitted. |
|
* All MAC address processing is suppressed. |
|
* ARP is disabled. |
|
|
|
If NET_SLIP is not selected, then Ethernet will be used (there is |
|
no need to define anything special in the configuration file to use |
|
Ethernet -- it is the default). |
|
|
|
