Setting link parameters on a netdevice changes the value
of if_nlmsg_size(), therefore it is necessary to recalculate
min_ifinfo_dump_size.

Applied, but:

+ min_ifinfo_dump_size = max_t(u16, if_nlmsg_size(dev),
+ min_ifinfo_dump_size);
+



The second line is not properly indented, the first non-space
character should line up with the first column after the
openning parenthesis on the previous line.

I fixed this up, but really this was a lot of tooth pulling to
get you to post this patch correctly. You cannot consume this
much maintainer and reviewer resources in the future.
