NET_NOINT indicates that uIP is 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

---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_TCP_READAHEAD_BUFSIZE
|

int "TCP/IP read-ahead buffer size"
|

default 562
|
|
---help---
|
|
Read-ahead buffers allows buffering of TCP/IP packets when there is no
|
|
receive in place to catch the TCP packet. In that case, the packet
|
|
will be retained in the NuttX read-ahead buffers.
|
|
|
|
This setting specifies the size of one TCP/IP read-ahead buffer.
|
|
This should best be a equal to the maximum packet size (NET_BUFSIZE).

config NET_NTCP_READAHEAD_BUFFERS

Read-ahead buffers allows buffering of TCP/IP packets when there is no
|
|
receive in place to catch the TCP packet. In that case, the packet
|
|
will be retained in the NuttX read-ahead buffers.
|
|
|
|
This setting specifies the number of TCP/IP read-ahead buffers This
|
|
value can be set to zero to disable all TCP/IP read-ahead buffering.
|
|
You might want to disable TCP/IP read-ahead buffering on a highly
|
|
memory constained system that does not have any TCP/IP packet rate
|
|
issues.
|
|
|
|
config NET_TCP_RECVDELAY
|
|
int "TCP Rx delay"
|
|
default 0
|
|
---help---
|
|
If NET_NTCP_READAHEAD_BUFFERS is zero, then there will be no buffering
|
|
of TCP/IP packets: Any TCP/IP packet received will be ACKed, but its contents
|
|
will be dropped in the bit-bucket.
|
|
|
|
One low-performance option is delay for a short period of time after a
|
|
TCP/IP packet is received to see if another comes right behind it. Then
|
|
the packet data from both can be combined. This option only makes since
|
|
if performance is not an issue and you need to handle short bursts of
|
|
small, back-to-back packets. The delay is in units of deciseconds.

---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).
