HedongGao opened a new pull request, #3284:
URL: https://github.com/apache/nuttx-apps/pull/3284
## Summary
The Nuttx network protocol stack supports the Vlan module, and netlib needs
to support Vlan related apis.
## Impact
Users can add or delete Vlan interfaces through the netlib api interface.
## Testing
`
#include <stdio.h>
#include <string.h>
#include <unistd.h>
#include <errno.h>
#include <netutils/netlib.h>
#define TEST_IFNAME "eth0" // Change to your actual base interface name
#define TEST_VLANID 100 // VLAN ID to test
#define TEST_VLANIF "eth0.100" // Expected VLAN interface name
int main(void)
{
int ret;
printf("Testing netlib_add_vlan()...\n");
ret = netlib_add_vlan(TEST_IFNAME, TEST_VLANID);
if (ret == 0)
{
printf("netlib_add_vlan: SUCCESS (added VLAN %d to %s)\n",
TEST_VLANID, TEST_IFNAME);
}
else
{
printf("netlib_add_vlan: FAILED (errno=%d: %s)\n", errno,
strerror(errno));
return 1;
}
// Optionally, you can check if the VLAN interface exists here
// For simplicity, we just try to delete it
// printf("Testing netlib_del_vlan()...\n");
// ret = netlib_del_vlan(TEST_VLANIF);
// if (ret == 0)
// {
// printf("netlib_del_vlan: SUCCESS (deleted VLAN interface %s)\n",
TEST_VLANIF);
// }
// else
// {
// printf("netlib_del_vlan: FAILED (errno=%d: %s)\n", errno,
strerror(errno));
// return 1;
// }
printf("VLAN add/delete test completed.\n");
return 0;
}
