* cases that we would otherwise complain about: |
|
| 1313 |
* (1) board doesn't support a NIC but the implicit "-net nic" |

* requested one; we'd otherwise complain about more NICs being |
|
| 1315 |
* specified than we support, and also that the vlan set up by |
|
| 1316 |
* the implicit "-net user" didn't have any NICs connected to it |
|
| 1317 |
* (2) CONFIG_SLIRP not set: we'd otherwise complain about the |
|
| 1318 |
* implicit "-net nic" setting up a nic that wasn't connected to |
|
| 1319 |
* anything. |
