zhhyu7 opened a new pull request, #17899:
URL: https://github.com/apache/nuttx/pull/17899
## Summary
urgent data needs to be treated as normal data when CONFIG_NET_TCPURGDATA
disable. some test sets will verify this behavior, correct the processing logic.
## Impact
tcp urgent data.
## Testing
sim:matter with host and disable CONFIG_NET_TCPURGDATA.
test code on the host:
```
#define SERVER_IP "10.0.1.2"
#define PORT 7777
#define BUFFER_SIZE 1024
sockfd = socket(AF_INET, SOCK_STREAM, 0);
connect(sockfd, (struct sockaddr *)&server_addr, sizeof(server_addr));
send(sockfd, "oob", strlen("oob"), MSG_OOB);
send(sockfd, "hello", strlen("hello"), 0);
```
test code on the NuttX:
```
#define SERVER_IP "0.0.0.0"
#define PORT 7777
#define BUFFER_SIZE 1024
server_fd = socket(AF_INET, SOCK_STREAM, 0);
bind(server_fd, (struct sockaddr *)&server_addr, sizeof(server_addr));
listen(server_fd, 5);
client_fd = accept(server_fd, (struct sockaddr *)&client_addr, &addr_len);
ret = recv(client_fd, buffer, BUFFER_SIZE, 0);
printf("Received message: [%d] %s\n", ret, buffer);
```
test log without this change:
```
NuttShell (NSH) NuttX-12.12.0
MOTD: username=admin password=Administrator
nsh> hello
Received message: [5] hello
nsh>
```
test log with this change:
```
NuttShell (NSH) NuttX-12.12.0
MOTD: username=admin password=Administrator
nsh> hello
Received message: [8] oobhello
nsh>
```
