+Subject: nft: fix interface comparisons in `-C` commands
+
+Commit 9ccae6397475 ("nft: Leave interface masks alone when parsing from
+kernel") removed code which explicitly set interface masks to all ones.  The
+result of this is that they are zero.  However, they are used to mask interfaces
+in `is_same_interfaces`.  Consequently, the masked values are alway zero, the
+comparisons are always true, and check commands which ought to fail succeed:
+
+  # iptables -N test
+  # iptables -A test -i lo \! -o lo -j REJECT
+  # iptables -v -L test
+  Chain test (0 references)
+   pkts bytes target     prot opt in     out     source               destination
+      0     0 REJECT     all  --  lo     !lo     anywhere             anywhere             reject-with icmp-port-unreachable
+  # iptables -v -C test -i abcdefgh \! -o abcdefgh -j REJECT
+  REJECT  all opt -- in lo out !lo  0.0.0.0/0  -> 0.0.0.0/0   reject-with icmp-port-unreachable
+
+Remove the mask parameters from `is_same_interfaces`.  Add a test-case.
