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

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).
