All -
The 4.20 linux kernel has a bug with sending link addresses to
user-space causing some of them not to be read. The tl;dr; is that
after one skb of data sent up, the data is stopped from being sent.
If you have a small number of addresses assigned to a box, then you
will probably not notice a problem. At this time I would not
recommend using linux kernel 4.20 for production network uses. The
commit that fixes this is this:

netlink: fixup regression in RTM_GETADDR
It is my understanding that this was introduced in 4.19-next. This
fix should be available in one of the upcoming 4.20.X releases as I
understand it.
thanks!
