Jakub Kicinski 3b39d73cc3 bpftool: Fix truncated netlink dumps ...

Netlink requires that the recv buffer used during dumps is at least
min(PAGE_SIZE, 8k) (see the man page). Otherwise the messages will
get truncated. Make sure bpftool follows this requirement, avoid
missing information on systems with large pages.
