cd67e66f8e monitor: Fix ARRAY output 
Commit 3ff9f59ba1 ("monitor: Print MAC_ADDRS array") introduced a
small bug where some arguments were erroneously printed as an address.

b9d97c9d87 monitor: change naming of Microsoft OUI 
Inside print_ie_vendor, the Microsoft OUI is checked for a WPA IE. The
variable name for the OUI was wfa_oui, but this OUI is not actually the
WiFi-Alliance (sometimes refered to as 'wfa') but rather the Microsoft
OUI.

FILS. Also changed "SAE Data" to "Auth Data" since its now used for
both SAE and FILS.

3b801526f0 monitor: allow monitor to support other MIC lengths 
Unfortunately there is no way to determine the MIC length just from the
eapol frame. 802.11 defined AKMs define the MIC length, but non 802.11
AKMs (e.g. OWE) can define their own MIC length. For this reason it seem
infeasable to track these special AKM's data flow to determine the MIC
length.

To work around this we can just try different MIC lengths (since there
are only 3 after all). This allows us to get key data length and see if
the total packet size equals the frame length + key data length. If the
sizes don't match we can try the next MIC length.

374b367ba4 eapol: allow 16, 24 and 32 byte MIC lengths 
The MIC length was hard coded to 16 bytes everywhere, and since several
AKMs require larger MIC's (24/32) this needed to change. The main issue
was that the MIC was hard coded to 16 bytes inside eapol_key. Instead
of doing this, the MIC, key_data_length, and key_data elements were all
bundled into key_data[0]. In order to retrieve the MIC, key_data_len,
or key_data several macros were introduced which account for the MIC
length provided.

A consequence of this is that all the verify functions inside eapol now
require the MIC length as a parameter because without it they cannot
determine the byte offset of key_data or key_data_length.

The MIC length for a given handshake is set inside the SM when starting
EAPoL. This length is determined by the AKM for the handshake.

37173350e2 monitor: move inclusion of linux headers after libc ones 
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.

e6765c1e9b monitor: Actually print management frame subtype 
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.

0e108f9727 monitor: Remove GENL_ID_GENERATE 
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.

6d652fb743 monitor: Support arbitrarily long bitfields 
Support arbitrarily long bitfields by providing field and mask values
as arrays with their length measured in bytes. Some of the IE fields
easily reach 80 bits or more, thus easily overrunning any integer sizes
used by the OS architecture.
