The recommended netlink buffer size is based on the system's page size,
which means that the current size is far too small for systems with 16k
or 64k pages, such as Asahi Linux or RHEL's kernel-64k for ARM64. On
these systems, the server fails to start with errors like this:
Error: Decode error occurred: invalid netlink buffer: length field says 1444 the buffer is 1260 bytes long
Instead, follow the kernel's own netlink docs to compute the buffer
size. The approach here matches the approach merged into Chromium
recently:
https://chromium-review.googlesource.com/c/chromium/src/+/4312885
also introduces a new `netlink-request` crate to help modularize the netlink code. this currently depends on a fork of the `netlink` project, but we should be able to use the official version soon.
