[pve-devel] [PATCH manager v2 08/13] ui: form: add MultiPCISelector

[Dominik Csapak <d.csapak@proxmox.com>]

this is a grid field for selecting multiple pci devices at once, like we
need for the mapped pci ui. There we want to be able to select multiple
devices such that one gets selected automatically

we can select a whole slot here, but that disables selecting the
individual functions of that device. we can also not select multiple
devices with different properties (e.g. vendor) so that the user
cannot select a set of pci devices which are not similar
