From d131ee36bcd2ff923f8678bea6f8bc6dfe6da7bb Mon Sep 17 00:00:00 2001
From: Phil Sutter <psutter@redhat.com>

Subject: [PATCH] expr: Repurpose struct expr_ops::max_attr field
JIRA: https://issues.redhat.com/browse/RHEL-28515
Upstream Status: libnftnl commit 4ed45d7bbbb9f914c934af327ee0271bcc909302
commit 4ed45d7bbbb9f914c934af327ee0271bcc909302
Author: Phil Sutter <phil@nwl.cc>
Date: Wed Dec 13 14:56:49 2023 +0100
expr: Repurpose struct expr_ops::max_attr field
Instead of holding the maximum kernel space (NFTA_*) attribute value,
use it to hold the maximum expression attribute (NFTNL_EXPR_*) value
instead. This will be used for index boundary checks in an attribute
policy array later.
