2011-10-05xen: netback: convert to SKB paged frag API.Ian Campbell
netback currently uses frag->page to store a temporary index reference while processing incoming requests. Since frag->page is to become opaque switch instead to using page_offset. Add a wrapper to tidy this up and propagate the fact that the indexes are only u16 through the code (this was already true in practice but unsigned long and in were inconsistently used as variable and parameter types) Signed-off-by: Ian Campbell <ian.campbell@citrix.com> Cc: Ian Campbell <ian.campbell@citrix.com> Cc: xen-devel@lists.xensource.com Cc: netdev@vger.kernel.org Signed-off-by: David S.

2011-10-05ixgbe: get pauseparam autonegMika Lansirinne
There is a problem in the ixgbe driver with the reporting of the flow control parameters. The autoneg parameter is shown to be of if *either* it really is off, or current modes for both tx and rx are off. The problem is seen when the parameters are read or set when the link is down. In this case, the driver sees that tx and rx are currently off and therefore autoneg parameter is incorrectly reported to be off too. Also, the ethtool binary can not set the autoneg off since it sees that it already is. When a link later comes up, the autonegotiation is carried out normally and the driver later on reports the autoneg parameter to be on (as it is) and then it can also be changed with ethtool. The patch is made against v3.0 kernel, but the problem seems to be there since v2.6.30-rc1. Reviewer comments: What we are trying to do is to disable flow control while the cable is disconnected. Since ixgbe defaults to full flow control, we call ethtool -A autoneg off rx off tx off while the cable is disconnected. This doesn't work, because the driver sets hw->fc.current_mode = ixgbe_fc_none if the cable is unplugged. ixgbe_get_pauseparam() then reports to ethtool that nothing needs to be done. The code fixes this, but it might have some unknown consequences.

2011-10-03libertas: detect TX lockups and reset hardwareDaniel Drake
Recent patches added support for resetting the SD8686 hardware when commands time out, which seems to happen quite frequently soon after resuming the system from a Wake-on-WLAN-triggered resume. At http://dev.laptop.org/ticket/10969 we see the same thing happen with transmits. In this case, the hardware will fail to respond to a frame passed for transmission, and libertas (correctly) will block all further commands and transmissions as the hardware can only deal with one thing at a time. This results in a lockup while the system waits indefinitely for the dead card to respond. Hook up a TX lockup timer to detect this and reset the hardware.

2011-10-03net: xen-netback: correctly restart Tx after a VM restore/migrateDavid Vrabel
If a VM is saved and restored (or migrated) the netback driver will no longer process any Tx packets from the frontend. xenvif_up() does not schedule the processing of any pending Tx requests from the front end because the carrier is off. Without this initial kick the frontend just adds Tx requests to the ring without raising an event (until the ring is full). This was caused by 47103041e91794acdbc6165da0ae288d844c820b (net: xen-netback: convert to hw_features) which reordered the calls to xenvif_up() and netif_carrier_on() in xenvif_connect().

2011-10-03bonding: properly stop queuing work when requestedAndy Gospodarek
During a test where a pair of bonding interfaces using ARP monitoring were both brought up and torn down (with an rmmod) repeatedly, a panic in the timer code was noticed. I tracked this down and determined that any of the bonding functions that ran as workqueue handlers and requeued more work might not properly exit when the module was removed. There was a flag protected by the bond lock called kill_timers that is set when the interface goes down or the module is removed, but many of the functions that monitor link status now unlock the bond lock to take rtnl first. There is a chance that another CPU running the rmmod could get the lock and set kill_timers after the first check has passed. This patch does not allow any function to queue work that will make itself run unless kill_timers is not set. I also noticed while doing this work that bond_resend_igmp_join_requests did not have a check for kill_timers, so I added the needed call there as well.

2011-09-30mac80211: implement uAPSDJohannes Berg
Add uAPSD support to mac80211. This is probably not possible with all devices, so advertising it with the cfg80211 flag will be left up to drivers that want it. Due to my previous patches it is now a fairly straight-forward extension. Drivers need to have accurate TX status reporting for the EOSP frame. For drivers that buffer themselves, the provided APIs allow releasing the right number of frames, but then drivers need to set EOSP and more-data themselves. This is documented in more detail in the new code itself. Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2011-09-30mac80211: let drivers inform it about per TID buffered framesJohannes Berg
For uAPSD implementation, it is necessary to know on which ACs frames are buffered. mac80211 obviously knows about the frames it has buffered itself, but with aggregation many drivers buffer frames. Thus, mac80211 needs to be informed about this. For now, since we don't have APSD in any form, this will unconditionally set the TIM bit for the station but later with uAPSD only some ACs might cause the TIM bit to be set. ath9k is the only driver using this API and I only modify it in the most basic way, it won't be able to implement uAPSD with this yet. But it can't do that anyway since there's no way to selectively release frames to the peer yet. Since drivers will buffer frames per TID, let them inform mac80211 on a per TID basis, mac80211 will then sort out the AC mapping itself.
