This allows both hostapd and wpa_supplicant to be used to derive and configure keys for GCMP. This is quite similar to CCMP key configuration, but a different cipher suite and somewhat different rules are used in cipher selection. It should be noted that GCMP is not included in default parameters at least for now, so explicit pairwise/group configuration is needed to enable it. This may change in the future to allow GCMP to be selected automatically in cases where CCMP could have been used. This commit does not included changes to WPS or P2P to allow GCMP to be used.
