to fix compilation against MUSL libc.
The struct ethhdr does exists in netinet/if_ether.h and linux/if_ether.h
so including the linux headers after the libc headers lets libc_compat.h
work as intended.
The subtype was only printed if mpdu_validate had returned an error for
the frame, i.e. would not be printed for well formed frames. This was
probably an intent to avoid printing the frame subtype after all the
conents of the body frame had been printed already, but iwmon only
supports printing of Authentication and Deauthentication frames so far.
Kernel v4.10 and later no longer export GENL_ID_GENERATE (which was
defined as 0). iwd was using this symbol to check for unmodified local
values rather than to ask for a dynamically generated netlink ID anyway,
so it makes sense to use the value 0 directly. This will work with
kernels before and after the GENL_ID_GENERATE change.
