URL: https://github.com/apache/nuttx/issues/11223
When running Nuttx `sim:tcpblaster` in GDB , I am encountering a problem to
access the network.
I cannot seem to access or to ping either the gateway or dns 8.8.8.8.
I tried to set kernel capabilities of gdb to access the tap device but no
success
```
sudo setcap cap_net_admin+ep /usr/bin/gdb
```
Nuttx version: master branch b5d640acc
Here is some logs wit hNetwork Debug Features enabled.
Ping failure:
