2012-10-24rtlwifi: pass rx setup error code to callerChristian Lamparter
If _rtl_usb_receive fails, the device is probably not ready. Hence the error code should be passed to the caller, so it can react accordingly and notify the user.

Pull networking changes from David Miller: 1) GRE now works over ipv6, from Dmitry Kozlov. 2) Make SCTP more network namespace aware, from Eric Biederman. 3) TEAM driver now works with non-ethernet devices, from Jiri Pirko. 4) Make openvswitch network namespace aware, from Pravin B Shelar. 5) IPV6 NAT implementation, from Patrick McHardy. 6) Server side support for TCP Fast Open, from Jerry Chu and others. 7) Packet BPF filter supports MOD and XOR, from Eric Dumazet and Daniel Borkmann. 8) Increate the loopback default MTU to 64K, from Eric Dumazet. 9) Use a per-task rather than per-socket page fragment allocator for outgoing networking traffic. This benefits processes that have very many mostly idle sockets, which is quite common. From Eric Dumazet. 10) Use up to 32K for page fragment allocations, with fallbacks to smaller sizes when higher order page allocations fail. Benefits are a) less segments for driver to process b) less calls to page allocator c) less waste of space. From Eric Dumazet. 11) Allow GRO to be used on GRE tunnels, from Eric Dumazet. 12) VXLAN device driver, one way to handle VLAN issues such as the limitation of 4096 VLAN IDs yet still have some level of isolation. From Stephen Hemminger. 13) As usual there is a large boatload of driver changes, with the scale perhaps tilted towards the wireless side this time around. Fix up various fairly trivial conflicts, mostly caused by the user namespace changes. * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net-next: (1012 commits) hyperv: Add buffer for extended info after the RNDIS response message. hyperv: Report actual status in receive completion packet hyperv: Remove extra allocated space for recv_pkt_list elements hyperv: Fix page buffer handling in rndis_filter_send_request() hyperv: Fix the missing return value in rndis_filter_set_packet_filter() hyperv: Fix the max_xfer_size in RNDIS initialization vxlan: put UDP socket in correct namespace vxlan: Depend on CONFIG_INET sfc: Fix the reported priorities of different filter types sfc: Remove EFX_FILTER_FLAG_RX_OVERRIDE_IP sfc: Fix loopback self-test with separate_tx_channels=1 sfc: Fix MCDI structure field lookup sfc: Add parentheses around use of bitfield macro arguments sfc: Fix null function pointer in efx_sriov_channel_type vxlan: virtual extensible lan igmp: export symbol ip_mc_leave_group netlink: add attributes to fdb interface tg3: unconditionally select HWMON support when tg3 is enabled.

There are a number of problems that occur for the latest version of the Realtek RTL8188CE device with the in-kernel driver. These include selection of the wrong firmware, and system lockup.

2012-07-17rtlwifi: rtl8192de: Fix phy-based version calculationForest Bond
Commit d83579e2a50ac68389e6b4c58b845c702cf37516 incorporated some changes from the vendor driver that made it newly important that the calculated hardware version correctly include the CHIP_92D bit, as all of the IS_92D_* macros were changed to depend on it. However, this bit was being unset for dual-mac, dual-phy devices. The vendor driver behavior was modified to not do this, but unfortunately this change was not picked up along with the others. This caused scanning in the 2.4GHz band to be broken, and possibly other bugs as well. This patch brings the version calculation logic in parity with the vendor driver in this regard, and in doing so fixes the regression. However, the version calculation code in general continues to be largely incoherent and messy, and needs to be cleaned up.

2012-07-12rtlwifi: rtl8192cu: Change buffer allocation for synchronous readsLarry Finger
In commit a7959c1, the USB part of rtlwifi was switched to convert _usb_read_sync() to using a preallocated buffer rather than one that has been acquired using kmalloc. Although this routine is named as though it were synchronous, there seem to be simultaneous users, and the selection of the index to the data buffer is not multi-user safe. This situation is addressed by adding a new spinlock. The routine cannot sleep, thus a mutex is not allowed.

There are also lots of new drivers, pimarily gadget, but others as well. We deleted a staging driver, which was nice, and finally dropped the obsolete usbfs code, which will make Al happy to never have to touch that again. There were some build errors in the tree that linux-next found a few days ago, but those were fixed by the most recent changes (all were due to us not building with CONFIG_PM disabled.)

2012-05-18USB: Disable hub-initiated LPM for comms devices.Sarah Sharp
Hub-initiated LPM is not good for USB communications devices. Comms devices should be able to tell when their link can go into a lower power state, because they know when an incoming transmission is finished. Ideally, these devices would slam their links into a lower power state, using the device-initiated LPM, after finishing the last packet of their data transfer. If we enable the idle timeouts for the parent hubs to enable hub-initiated LPM, we will get a lot of useless LPM packets on the bus as the devices reject LPM transitions when they're in the middle of receiving data. Worse, some devices might blindly accept the hub-initiated LPM and power down their radios while they're in the middle of receiving a transmission. The Intel Windows folks are disabling hub-initiated LPM for all USB communications devices under a xHCI USB 3.0 host. In order to keep the Linux behavior as close as possible to Windows, we need to do the same in Linux. Set the disable_hub_initiated_lpm flag for for all USB communications drivers. I know there aren't currently any USB 3.0 devices that implement these class specifications, but we should be ready if they do.

2012-05-14rtlwifi: fix for race condition when firmware is cachedLarry Finger
In commit b0302ab, the rtlwifi family of drivers was converted to use asynchronous firmware loading. Unfortumately, the implementation was racy, and the ieee80211 routines could be started before rtl_init_core() was called to setup the data. This patch fixes the bug noted in https://bugzilla.kernel.org/show_bug.cgi?id=43187.

So we clean all this up and in doing so enable cut-specific code paths for cuts C and D, which would not have been executed because the CHIP_92D_{C,D}_CUT constants were wrong and the cut version was thus recorded incorrectly.
