[Bug 1720126] Re: [ip link] Message truncated error for large number of passthrough VFs

I don't think the Trusty armhf autopkgtest test is likely to be a regression. It doesn't appear to have ever passed before and the error looks associated with the test runner rather than iproute2 itself. Given the nature of the patch, it seems unlikely to me to be caused by this update. I think

[Bug 1720126] Re: [ip link] Message truncated error for large number of passthrough VFs

The trusty upload seems to have an armhf autopkgtest regression - looks really strange and I see it failed once already. I think it might be good to run the autopkgtest suite with no triggers to see if it's an unrelated regression or not. Could anyone take a look at that?
