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

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

---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).

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

issues.

config NET_TCP_RECVDELAY

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.

bool "Enable packet splitting"

default n

---help---
|
|
send() will not return until the the transfer has been ACKed by the
|
|
recipient. But under RFC 1122, the host need not ACK each packet
|
|
immediately; the host may wait for 500 MS before ACKing. This
|
|
combination can cause very slow performance with small transfers are
|
|
made to an RFC 1122 client. However, the RFC 1122 must ACK at least
|
|
every second (odd) packet.
|
|
|
|
This option enables logic to trick the RFC 1122 host be exploiting
|
|
this last RFC 1122 requirement: If an odd number of packets were to
|
|
be sent, then send() will split the last even packet to guarantee
|
|
that an even number of packets will be sent and the RFC 1122 host
|
|
will ACK the final packet immediately.

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).
