[pve-devel] [PATCH proxmox-firewall 1/3] nftables: add support for auto-merge set option

[Stefan Hanreich <s.hanreich@proxmox.com>]

nftables sets do not support overlapping ranges in ipsets with the
interval flag enabled, unless explicitly enabled via auto-merge. This
option has not yet been exposed by proxmox-nftables, so add it to the
library. This requires at least nftables 1.1.0 to work, which is
available since Debian trixie.
