There have been reports about 'ip addr' printing "Message truncated" on systems with large numbers of VFs. Although I haven't been able to get my hands on hardware suitable to reproduce this, increasing the dump buffer has been reported to resolve the issue. For want of a better idea, just double the buffer size to 32k. Feels like this opportunistic buffer size selection is rather workarounding a design flaw in libnetlink or maybe even the netlink protocol itself.
