2008-03-25mac80211: allows driver to request a Phase 1 RX keyEmmanuel Grumbach
This patch makes mac80211 able to send a phase1 key for TKIP decryption. This is needed for drivers that don't do the rekeying by themselves (i.e. iwlwifi). Upon IV16 wrap around, the packet is decrypted in SW, if decryption is ok, mac80211 calls to update_tkip_key with a new phase 1 RX key.

2008-03-25mac80211: get a TKIP phase key from skbEmmanuel Grumbach
This patch makes mac80211 able to compute a TKIP key from an skb. The requested key can be a phase 1 or a phase 2 key. This is useful for drivers who need to provide tkip key to their HW to enable HW encryption.

2008-03-25iwlwifi-2.6: RX status translation to old schemeEmmanuel Grumbach
This patch adds translation for the RX status of an incoming packet. The incoming status has to be translated to the old scheme in order to know if the decryption has been done, MIC failure has occured, TTAK is valid etc... This translation is mandatory for all RX packets when using 5300 and for all HT packets using 4965.

2008-03-25iwlwifi-2.6: Cleans up set_key flowEmmanuel Grumbach
This patch cleans up the set_key flow. Rxon with hw encryption bit set is not sent upon each call to set_key. Separation is made between global key (WEP) and dynamic key (TKIP + CCMP and WEP in some cases).

2008-03-25libertas: convert GET_LOG to a direct commandHolger Schurig
Now uses __lbs_cmd() to get the "log" (it's actually more a snapshot of various counters, not a sequential log). Besides the "mechanical" convertion the patch add the following logical changes: * Removes the priv->logmsg variable, it was only used in one place anyway, also don't blindly get the counters when associating. Getting the counters then the user asks via WEXT for them is good enought. * don't set wstats.discard.fragment with log.rxfrag, because the latter is a counter for successfully received packets, not for fragmented packets.

2008-03-25libertas: fix scheduling while atomic bug in CMD_MAC_CONTROLHolger Schurig

2008-03-25libertas: make a handy lbs_cmd_async() commandHolger Schurig
This uses a static lbs_cmd_async_callback function, which is a noop. Just setting the callback argument to __lbs_cmd_async() to NULL won't work, because then the cmdnode wouldn't be released. This also makes __lbs_cmd_async() a static method, which is now only used by lbs_cmd() and lbs_cmd_async().

2008-03-25[XFRM] MIP6: Fix address keys for routing search.YOSHIFUJI Hideaki
Each MIPv6 XFRM state (DSTOPT/RH2) holds either destination or source address to be mangled in the IPv6 header (that is "CoA"). On Inter-MN communication after both nodes binds each other, they use route optimized traffic two MIPv6 states applied, and both source and destination address in the IPv6 header are replaced by the states respectively. The packet format is correct, however, next-hop routing search are not. This patch fixes it by remembering address pairs for later states.
