[pve-devel] [PATCH ifupdown2] patch: fix bond mac address at boot.

[Alexandre Derumier <aderumier@odiso.com>]

since systemd v241, like for bridge, the bond mac is setup
randomly at boot, instead inherit from first slave.

Then, on next ifreload, ifupdown2 was already fixing it,
but with an down/up of the bond (with potentials impact on the network).

This patch have been sent upstream:
https://github.com/CumulusNetworks/ifupdown2/pull/270

This patch is applying fine too for ifupdown2 for proxmox7
