Restoring rulesets containing dynamic sets with counters

[Frank Myhr <fmyhr@xxxxxxxxxxx>]

Hi,

I've created a ruleset that contains several dynamic sets with counters 
that are incremented from the packet path using rules like:
update @suspect { ip saddr counter }

After awhile in operation, "nft list ruleset" produces output like:
table ip ip_filter {
	set suspect {
		type ipv4_addr
		size 65535
		flags dynamic,timeout
		timeout 30d
		gc-interval 1d
		elements = { 1.2.3.4 expires 19d23h52m27s576ms counter packets 51 
bytes 17265 }
	}

But "nft -f" then chokes when loading the saved ruleset, with
"Error: syntax error, unexpected counter, expecting comma or '}'".

For now I can use sed to blank the counter text before reloading the 
ruleset (as after reboot). That's bit clunky, and obviously loses the 
counter values.

I do want to keep the dynamically-added elements across reboot. Is there 
a better way to do so?

Thanks,
Frank
