* bcmdhd: Enable Ad-Hoc (IBSS) modeBruno Randolf2013-03-191-2/+63
| | | | | | | | | | Enable Ad-Hoc (IBSS) mode for bcmdhd. We basically just need to set the interface flag and avoid some P2P specific settings while scanning. Also add the "station get" command for IBSS mode. Change-Id: Ice320bc65b0b9b738fa09acc1e3dea2a58805ad9 Signed-off-by: Bruno Randolf <br1@einfach.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | [ Upstream commit a2af139ff1cd85df586690ff626619ab1ee88b0a ] Marvell 88E8001 on an ASUS P5NSLI motherboard is unable to send/receive packets on a system with >4gb ram unless a 32bit DMA mask is used. This issue has been around for years and a fix was sent 3.5 years ago, but there was some debate as to whether it should instead be fixed as a PCI quirk. http://www.spinics.net/lists/netdev/msg88670.html However, 18 months later a similar workaround was introduced for another chipset exhibiting the same problem. http://www.spinics.net/lists/netdev/msg142287.html Signed-off-by: Graham Gower <graham.gower@gmail.com> Signed-off-by: Jan Ceuleers <jan.ceuleers@computer.org> Acked-by: Stephen Hemminger <shemminger@vyatta.com> Signed-off-by: David S.

| * | r8169: fix unsigned int wraparound with TSOJulien Ducourthial2012-10-131-6/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | commit 477206a018f902895bfcd069dd820bfe94c187b1 upstream. The r8169 may get stuck or show bad behaviour after activating TSO : the net_device is not stopped when it has no more TX descriptors. This problem comes from TX_BUFS_AVAIL which may reach -1 when all transmit descriptors are in use. The patch simply tries to keep positive values. Tested with 8111d(onboard) on a D510MO, and with 8111e(onboard) on a Zotac 890GXITX.

With runtime PM, if the ethernet cable is disconnected, the device is transitioned to D3 state to conserve energy. If the system is shutdown in this state, any register accesses in rtl_shutdown are dropped on the floor. As the device was programmed by .runtime_suspend() to wake on link changes, it is thus brought back up as soon as the link recovers. Resuming every suspended device through the driver core would slow things down and it is not clear how many devices really need it now. Original report and D0 transition patch by Sameer Nanda. Patch has been changed to comply with advices by Rafael J. Wysocki and the PM folks.

| * | r8169: Rx FIFO overflow fixes.Francois Romieu2012-10-131-30/+24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | commit 811fd3010cf512f2e23e6c4c912aad54516dc706 upstream. Realtek has specified that the post 8168c gigabit chips and the post 8105e fast ethernet chips recover automatically from a Rx FIFO overflow. The driver does not need to clear the RxFIFOOver bit of IntrStatus and it should rather avoid messing it. The implementation deserves some explanation: 1. events outside of the intr_event bit mask are now ignored. It enforces a no-processing policy for the events that either should not be there or should be ignored. 2. RxFIFOOver was already ignored in rtl_cfg_infos[RTL_CFG_1] for the whole 8168 line of chips with two exceptions: - RTL_GIGA_MAC_VER_22 since b5ba6d12bdac21bc0620a5089e0f24e362645efd ("use RxFIFO overflow workaround for 8168c chipset."). This one should now be correctly handled. - RTL_GIGA_MAC_VER_11 (8168b) which requires a different Rx FIFO overflow processing. Though it does not conform to Realtek suggestion above, the updated driver includes no change for RTL_GIGA_MAC_VER_12 and RTL_GIGA_MAC_VER_17. Both are 8168b. RTL_GIGA_MAC_VER_12 is common and a bit old so I'd rather wait for experimental evidence that the change suggested by Realtek really helps or does not hurt in unexpected ways. Removed case statements in rtl8169_interrupt are only 8168 relevant. 3. RxFIFOOver is masked for post 8105e 810x chips, namely the sole 8105e (RTL_GIGA_MAC_VER_30) itself.

And it would take about 2 ~ 5 seconds from link down to link up. If the delay of pm_schedule_suspend is not long enough, the device would enter runtime_suspend before link up. After link up, the device would wake up and reset PHY again. Then, you would find the driver keep in a loop of runtime_suspend and rumtime_resume.

The TSO cannot coexist with ASF management firmware though. The tg3 driver determines whether or not ASF is enabled by calling tg3_get_eeprom_hw_cfg(), which checks a particular bit of NIC memory. Commit dabc5c670d3f86d15ee4f42ab38ec5bd2682487d, entitled "tg3: Move TSO_CAPABLE assignment", accidentally moved the code that determines TSO capabilities earlier than the call to tg3_get_eeprom_hw_cfg(). As a consequence, the driver was attempting to determine TSO capabilities before it had all the data it needed to make the decision. This patch fixes the problem by revisiting and reevaluating the decision after tg3_get_eeprom_hw_cfg() is called.

| * | e1000e: Disable ASPM L1 on 82574Chris Boot2012-10-021-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | commit d4a4206ebbaf48b55803a7eb34e330530d83a889 upstream. ASPM on the 82574 causes trouble. Currently the driver disables L0s for this NIC but only disables L1 if the MTU is >1500. This patch simply causes L1 to be disabled regardless of the MTU setting.

We need to program the rfkill switch GPIO pin direction to input at device initialization time, not only when the interface is brought up. Doing this only when the interface is brought up could lead to rfkill detecting the switch is turned on erroneously and inability to create the interface and bringing it up.

The MCP2515 has a silicon bug causing repeated frame transmission, see section 5 of MCP2515 Rev. B Silicon Errata Revision G (March 2007). Basically, setting TXBnCTRL.TXREQ in either SPI mode (00 or 11) will eventually cause the bug. The workaround proposed by Microchip is to use mode 00 and send a RTS command on the SPI bus to initiate the transmission.

The TX queue selected for the skb may stall and trigger the TX watchdog repeatedly (since the problem skb will be retried after the TX reset). This issue is designated as CVE-2012-3412. Set the maximum number of TSO segments for our devices to 100. This should make no difference to behaviour unless the actual MSS is less than about 700. Increase the minimum TX queue size accordingly to allow for 2 worst-case skbs, so that there will definitely be space to add an skb after we wake a queue. To avoid invalidating existing configurations, change efx_ethtool_set_ringparam() to fix up values that are too small rather than returning -EINVAL.
