+ lldpctl indicates duplicate LLDP records.
+
+ [Test Case]
+
+ On a system with a bonded link, issue:
+
+ # lldpctl | grep PortDescr
+
+ and it will indicate duplicate records.
+
+ After applying the fix, issue the same command and duplicates will be
+ elided.
+
+ [Regression Potential]
+
+ The above issue is only seen on kernels newer than 4.19 (so 19.04+,
+ which implies 18.04.3's kernel). However, the bond-specific code in
+ lldpctl is only needed on kernels <= 2.6.27 per upstream, which is older
+ than any kernel in any supported Ubuntu. This fix allows future-proofs
+ lldpctl for the eventual HWE impact.

So I think this commit:
https://github.com/torvalds/linux/commit/6a9e461f6fe4434e6172304b69774daff9a3ac4c
has been backported to some -stable trees.
This makes lldpd < 1.0.3 duplicate entries. I think given both -stable
trees in existing Ubuntu and the HWE stack in 18.04 (even if only
18.04.3), we should backport
https://github.com/vincentbernat/lldpd/pull/307/commits/0638075c721323aa6aeab9c6ab282861f53c9f2f
to the source package in 18.04+.
