* mac80211: allows driver to request a Phase 1 RX keyEmmanuel Grumbach2008-03-25
| | | | | | | | | | | | | 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.

* mac80211: get a TKIP phase key from skbEmmanuel Grumbach2008-03-25
| | | | | | | | | | | 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.

* iwlwifi-2.6: RX status translation to old schemeEmmanuel Grumbach2008-03-25
| | | | | | | | | | | | 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.

* libertas: convert GET_LOG to a direct commandHolger Schurig2008-03-25
| | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | HTB is event driven algorithm and part of its work is to apply scheduled events at proper times. It tried to defend itself from livelock by processing only limited number of events per dequeue. Because of faster computers some users already hit this hardcoded limit.

| * [TCP]: Let skbs grow over a page on fast peersHerbert Xu2008-03-22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | While testing the virtio-net driver on KVM with TSO I noticed that TSO performance with a 1500 MTU is significantly worse compared to the performance of non-TSO with a 16436 MTU. The packet dump shows that most of the packets sent are smaller than a page. Looking at the code this actually is quite obvious as it always stop extending the packet if it's the first packet yet to be sent and if it's larger than the MSS. Since each extension is bound by the page size, this means that (given a 1500 MTU) we're very unlikely to construct packets greater than a page, provided that the receiver and the path is fast enough so that packets can always be sent immediately. The fix is also quite obvious. The push calls inside the loop is just an optimisation so that we don't end up doing all the sending at the end of the loop. Therefore there is no specific reason why it has to do so at MSS boundaries. For TSO, the most natural extension of this optimisation is to do the pushing once the skb exceeds the TSO size goal. This is what the patch does and testing with KVM shows that the TSO performance with a 1500 MTU easily surpasses that of a 16436 MTU and indeed the packet sizes sent are generally larger than 16436. I don't see any obvious downsides for slower peers or connections, but it would be prudent to test this extensively to ensure that those cases don't regress.
