[PULL 07/11] docs/about/removed-features: Document removed CLI options from QEMU v3.0 |

These CLI options had been removed/replaced in QEMU v3.0. Still, some
people might want to update from older versions to the recent QEMU version,
so we should give some recommendations for the replacements in our
documentation.

+
+The term "vlan" was very confusing for most users in this context (it's about
+specifying a hub ID, not about IEEE 802.1Q or something similar), so this
+has been removed. To connect one NIC frontend with a network backend, either
+use ``-nic ...`` (e.g. for on-board NICs) or use ``-netdev ...,id=n`` together
+with ``-device ...,netdev=n`` (for full control over pluggable NICs). To
+connect multiple NICs or network backends via a hub device (which is what
+vlan did), use ``-nic hubport,hubid=x,...`` or
+``-netdev hubport,id=n,hubid=x,...`` (with ``-device ...,netdev=n``) instead.
