In v3.0.1-rc6 release network block macaddr value converts from upper to lower case

Network Block

Seems it is related with:
#1139

Adding resources:

      + network {
          + bridge    = "vmbr0"
          + firewall  = false
          + id        = 0
          + link_down = false
          + macaddr   = "AC:15:11:99:D5:11"
          + model     = "virtio"
          + tag       = 1111
        }

Removing resources:

      - network {
          - bridge    = "vmbr0" -> null
          - firewall  = false -> null
          - id        = 0 -> null
          - link_down = false -> null
          - macaddr   = "ac:15:11:99:d5:11" -> null
          - model     = "virtio" -> null
          - mtu       = 0 -> null
          - queues    = 0 -> null
          - rate      = 0 -> null
          - tag       = 1111 -> null
        }

I have some macaddr manipulations after VM provisioning (with provisioner "local-exec") and due to this change this action fails:

│ Error: Provider produced inconsistent final plan
│ 
│ When expanding the plan for terraform_data.* to include new values learned so far during apply, provider "terraform.io/builtin/terraform" produced an invalid new value for .triggers_replace[0]: was
│ cty.StringVal("AC:15:11:99:D5:11"), but now cty.StringVal("ac:15:11:99:d5:11").
│ 
│ This is a bug in the provider, which should be reported in the provider's own issue tracker.

@maksimsamt this was done on purpose to enforce the same case pve uses when it generates a mac address from the ui. As switching the case of the mac address counts as disconnecting and reconnecting the network interface.

Also, all mac address formats are valid, even octal as we use the binary representation of the mac address.

Would using lower-case mac addresses in your be a solution for you?

Personally prefer upper-case mac address, so could make it default to uppercase.

@Tinyblargon,

Yes, already changed in my solution logic to use lower case values.

Personally prefer upper-case mac address, so could make it default to uppercase.

The same to me, upper-case mac address is more readable.

@maksimsamt gonna try to figure out if i can preserve the format when returning it.

I'll add it to RC7.
