Unfortunately, the firmware only supports replay counters for a single GTK in D3, so that we should only upload the last key and use its replay counters. Since mac80211 key iteration will walk through the keys in order of their addition, simply use the same HW key index (1) for all GTKs, thus overwriting previous ones with newer ones.

Pull networking updates from David Miller: "This is a re-do of the net-next pull request for the current merge window. The only difference from the one I made the other day is that this has Eliezer's interface renames and the timeout handling changes made based upon your feedback, as well as a few bug fixes that have trickeled in. Highlights: 1) Low latency device polling, eliminating the cost of interrupt handling and context switches. Allows direct polling of a network device from socket operations, such as recvmsg() and poll(). Currently ixgbe, mlx4, and bnx2x support this feature. Full high level description, performance numbers, and design in commit 0a4db187a999 ("Merge branch 'll_poll'") From Eliezer Tamir. 2) With the routing cache removed, ip_check_mc_rcu() gets exercised more than ever before in the case where we have lots of multicast addresses. Use a hash table instead of a simple linked list, from Eric Dumazet. 3) Add driver for Atheros CQA98xx 802.11ac wireless devices, from Bartosz Markowski, Janusz Dziedzic, Kalle Valo, Marek Kwaczynski, Marek Puzyniak, Michal Kazior, and Sujith Manoharan. 4) Support reporting the TUN device persist flag to userspace, from Pavel Emelyanov. 5) Allow controlling network device VF link state using netlink, from Rony Efraim. 6) Support GRE tunneling in openvswitch, from Pravin B Shelar. 7) Adjust SOCK_MIN_RCVBUF and SOCK_MIN_SNDBUF for modern times, from Daniel Borkmann and Eric Dumazet. 8) Allow controlling of TCP quickack behavior on a per-route basis, from Cong Wang. 9) Several bug fixes and improvements to vxlan from Stephen Hemminger, Pravin B Shelar, and Mike Rapoport. In particular, support receiving on multiple UDP ports. 10) Major cleanups, particular in the area of debugging and cookie lifetime handline, to the SCTP protocol code. From Daniel Borkmann. 11) Allow packets to cross network namespaces when traversing tunnel devices. From Nicolas Dichtel. 12) Allow monitoring netlink traffic via AF_PACKET sockets, in a manner akin to how we monitor real network traffic via ptype_all. From Daniel Borkmann. 13) Several bug fixes and improvements for the new alx device driver, from Johannes Berg. 14) Fix scalability issues in the netem packet scheduler's time queue, by using an rbtree. From Eric Dumazet. 15) Several bug fixes in TCP loss recovery handling, from Yuchung Cheng. 16) Add support for GSO segmentation of MPLS packets, from Simon Horman. 17) Make network notifiers have a real data type for the opaque pointer that's passed into them. Use this to properly handle network device flag changes in arp_netdev_event(). From Jiri Pirko and Timo Teräs. 18) Convert several drivers over to module_pci_driver(), from Peter Huewe. 19) tcp_fixup_rcvbuf() can loop 500 times over loopback, just use a O(1) calculation instead. From Eric Dumazet. 20) Support setting of explicit tunnel peer addresses in ipv6, just like ipv4. From Nicolas Dichtel. 21) Protect x86 BPF JIT against spraying attacks, from Eric Dumazet. 22) Prevent a single high rate flow from overruning an individual cpu during RX packet processing via selective flow shedding. From Willem de Bruijn. 23) Don't use spinlocks in TCP md5 signing fast paths, from Eric Dumazet. 24) Don't just drop GSO packets which are above the TBF scheduler's burst limit, chop them up so they are in-bounds instead. Also from Eric Dumazet. 25) VLAN offloads are missed when configured on top of a bridge, fix from Vlad Yasevich. 26) Support IPV6 in ping sockets. From Lorenzo Colitti. 27) Receive flow steering targets should be updated at poll() time too, from David Majnemer. 28) Fix several corner case regressions in PMTU/redirect handling due to the routing cache removal, from Timo Teräs. 29) We have to be mindful of ipv4 mapped ipv6 sockets in upd_v6_push_pending_frames(). From Hannes Frederic Sowa. 30) Fix L2TP sequence number handling bugs, from James Chapman." * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net-next: (1214 commits) drivers/net: caif: fix wrong rtnl_is_locked() usage drivers/net: enic: release rtnl_lock on error-path vhost-net: fix use-after-free in vhost_net_flush net: mv643xx_eth: do not use port number as platform device id net: sctp: confirm route during forward progress virtio_net: fix race in RX VQ processing virtio: support unlocked queue poll net/cadence/macb: fix bug/typo in extracting gem_irq_read_clear bit Documentation: Fix references to defunct linux-net@vger.kernel.org net/fs: change busy poll time accounting net: rename low latency sockets functions to busy poll bridge: fix some kernel warning in multicast timer sfc: Fix memory leak when discarding scattered packets sit: fix tunnel update via netlink dt:net:stmmac: Add dt specific phy reset callback support. dt:net:stmmac: Add support to dwmac version 3.610 and 3.710 dt:net:stmmac: Allocate platform data only if its NULL. net:stmmac: fix memleak in the open method ipv6: rt6_check_neigh should successfully verify neigh if no NUD information are available net: ipv6: fix wrong ping_v6_sendmsg return value ...

git://git.kernel.org/pub/scm/linux/kernel/git/linville/wireless-next John W. Linville says: ==================== Yet one more pull request for wireless updates intended for 3.11... For the mac80211 bits, Johannes says: "Here we have a few memory leak fixes related to BSS struct handling mostly from Ben, including a fix for a more theoretical problem (associating while a BSS struct times out) from myself, a compilation warning fix from Arend, mesh fixes from Thomas, tracking the beacon bitrate (Alex), a bandwidth change event fix (Ilan) and some initial work for 5/10 MHz channels from Simon." Regarding the iwlwifi bits, Johannes says: "Emmanuel removed some unneeded/unsupported module parameters and adds a Bluetooth 1x1 lookup-table for some upcoming products. From Alex I have an older patch to add low-power receive support, this depended on a mac80211 commit that only just came in with the merge from wireless-next I did. Ilan made beacon timings better, and Eytan added some debug statements for thermal throttling. I have a few cleanups, a fix for a long-standing but rare warning, and, arguably the most important patch here, the firmware API version bump for the 7260/3160 devices." Also included is a Bluetooth pull -- Gustavo says: "Here goes a set of patches to 3.11. The biggest work here is from Andre Guedes on the move of the Discovery to use the new request framework. Other than that Johan provided a bunch of fixes to the L2CAP code. The rest are just small fixes and clean ups." On top of all that, there are a variety of updates and fixes to brcmfmac, rt2x00, wil6210, ath9k, ath10k, and a few others here and there. This also includes a pull of the wireless tree, in order to prevent some merge conflicts. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>

2013-06-27rt2x00: rt2800lib: fix default TX power check for RT55xxGabor Juhos
The code writes the default_power2 value into the TX field of the RFCSR50 register, however the condition in the if statement uses default_power1. Due to this, wrong TX power value might be written into the register. Use the correct value in the condition to fix the issue. Compile tested only.

The 3T/3R devices are using the tertiary PAs/LNAs however those are never turned on. Fix the code to turn on those on for such devices. Also modify the code to use switch statements to improve readability. Signed-off-by: Gabor Juhos <juhosg@openwrt.org> Acked-by: Gertjan van Wingerde <gwingerde@gmail.com> Signed-off-by: John W.

2013-06-27rt2x00: rt2800: increase EEPROM_SIZE to 512 bytesGabor Juhos
Ralink 3T chipsets are using a different EEPROM layout than the others. The EEPROM on these devices contain more data than the others which does not fit into 272 byte which the rt2800 driver actually uses. The Ralink reference driver defines EEPROM_SIZE to 512/1024 bytes for PCI/USB devices respectively. Increase the EEPROM_SIZE constant to 512 bytes, in order to make room for EEPROM data of 3T devices.

2013-06-25iwlwifi: mvm: Add support for Low Power RXAlexander Bondar
To improve power consumption in idle associated mode FW may lower RX power. This low linearity mode is acceptable for listening low rate RX such as beacons and groupcast. The driver enables LPRX only if PM is enabled and associated AP's beacon TX rate is 1Mbps or 6Mbps. LPRX RSSI threshold is used to limit a range where LPRX is applied.
