eapol: Pass actual PTK size to crypto_derive_pairwise_ptk()
...
It doesn't matter for crypto_derive_pairwise_ptk in non-SHA256 mode
but in the FT PTK derivation function, as well as in SHA256 mode all
bytes of the output do actually change with the PTK size.

We used to open a socket for each wireless interface. This patch uses a
single socket with an attached BPF to handle all EAPoL traffic via a
single file descriptor.

eapol: Store protocol version in eapol_sm
...
Instead of one global protocol_version, we now store it inside eapol_sm.
This allows us to use the same protocol version for our response as the
request from the authenticator.
For unit tests where we had protocol version mismatches, a new method is
introduced to explicitly set the protocol version to use.

Instead of passing the user_data parameter in every __eapol_rx_packet
call to be used by EAPOL in all tx_packet calls, add
eapol_sm_set_tx_user_data function that sets the value of user_data for
all subsequent tx_packet calls. This way tx_packet can be called from
places that are not necessarily inside an __eapol_rx_packet call.

Step 4 is always sent without encrypted Key Data according to Section

should always be 0. Thus it is safe to drop the !is_wpa condition.
