[Qemu-devel] [PATCH 3/6] Fixup info_str formatting

[Mark McLoughlin <markmc@redhat.com>]

The VLANClientState::info_str format isn't terribly consistent and
this patch moves towards it just containing the param strings
separated by a comma.

The type/model string is removed from info_str, and 'info network'
instead displays the vlan client name with the info_str.

There's a horrible little hack in net_cleanup() to parse a tap
client's info_str which I've also fixed up. The hack probably
shouldn't exist at all, though.
