["zhhyu7 (via GitHub)" <gi...@apache.org>]

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>
   ```
