565861976d Added support for using SHA256-based stronger key derivation for WPA2
IEEE 802.11w/D6.0 defines new AKMPs to indicate SHA256-based algorithms for
key derivation (and AES-CMAC for EAPOL-Key MIC). Add support for using new
AKMPs and clean up AKMP processing with helper functions in defs.h.

886a807fb5 Make proactive key caching working again
Function 'wpa_sm_set_config' used the argument 'config' as the network
context which is a pointer to a local variable of the function
'wpa_supplicant_rsn_supp_set_config'.

This is one reason why no proactive key was generated. This network
context never matched with the network context saved in the pmksa cache
entries.

The structure 'rsn_supp_config' has already a member 'network_ctx' which
is now filled in by this patch with 'ssid'.

3e2ad1b932 Fixed race condition between disassociation event and group key handshake
This avoids getting stuck in state where wpa_supplicant has canceled scans,
but the driver is actually in disassociated state. The previously used code
that controlled scan timeout from WPA module is not really needed anymore
(and has not been needed for past four years since authentication timeout
was separated from scan request timeout), so this can simply be removed to
resolved the race condition. As an extra bonus, this simplifies the
interface to WPA module.

a8e16edc86 Introduced new helper function is_zero_ether_addr()
Use this inline function to replace os_memcmp(addr,
"\x00\x00\x00\x00\x00\x00", ETH_ALEN) == 0.
