2012-07-10wlcore: always clear recovery flag during recovery_workArik Nemtsov
If recovery is called when the FW is off, we should clear the recovery flag. Otherwise we risk booting the driver in permanent pending-recovery state. Signed-off-by: Arik Nemtsov <arik@wizery.com> Signed-off-by: Luciano Coelho <coelho@ti.com>
2012-07-10wlcore: avoid debug prints during intended FW recoveryArik Nemtsov
Don't read the FW panic log or print other debug data when recovery is intended (i.e. FW type switch). This takes valuable time and can be confusing to the user. Signed-off-by: Arik Nemtsov <arik@wizery.com> Signed-off-by: Luciano Coelho <coelho@ti.com>
2012-07-10wlcore: remove recover cmd from testmodeArik Nemtsov
This command is buggy (doesn't take the mutex) and unused. Instead, the "start_recovery" file is used for the same purpose. Remove the code but keep the command constant to avoid breaking the testmode ABI. Signed-off-by: Arik Nemtsov <arik@wizery.com> Signed-off-by: Luciano Coelho <coelho@ti.com>
2012-07-10wlcore: don't stop tx queue via watermark if already stoppedArik Nemtsov
If a Tx queue is currently stopped because of our Tx watermark flow control, don't stop it again. This causes a warning to appear. Signed-off-by: Arik Nemtsov <arik@wizery.com> Signed-off-by: Luciano Coelho <coelho@ti.com>
2012-07-10wlcore/wl12xx/wl18xx: check min FW versionArik Nemtsov
Refuse to boot if the FW version is too old. The minimum version is set per chip, with the option of setting it per PG in the future. When boot fails because of an old FW, display a helpful message. Signed-off-by: Arik Nemtsov <arik@wizery.com> Signed-off-by: Luciano Coelho <coelho@ti.com>
2012-07-10wlcore: enable sched scan while connectedVictor Goldenshtein
New wl12xx firmware supports scheduled scans also while connected. Stop blocking sched scan requests when connected and add a quirk to block in hardware that don't support it (currently wl18xx doesn't). This requires FW version 6/7.3.10.2.112 for single-role and 6/7.5.6.0.25 for multi-role. Signed-off-by: Victor Goldenshtein <victorg@ti.com> Signed-off-by: Luciano Coelho <coelho@ti.com>

2012-07-09gianfar: fix potential sk_wmem_alloc imbalanceEric Dumazet
commit db83d136d7f753 (gianfar: Fix missing sock reference when processing TX time stamps) added a potential sk_wmem_alloc imbalance If the new skb has a different truesize than old one, we can get a negative sk_wmem_alloc once new skb is orphaned at TX completion. Now we no longer early orphan skbs in dev_hard_start_xmit(), this probably can lead to fatal bugs.

2012-07-09drivers/net/ethernet/broadcom/cnic.c: remove invalid reference to list ↵Julia Lawall
iterator variable If list_for_each_entry, etc complete a traversal of the list, the iterator variable ends up pointing to an address at an offset from the list head, and not a meaningful structure. Thus this value should not be used after the end of the iterator. There does not seem to be a meaningful value to provide to netdev_warn. Replace with pr_warn, since pr_err is used elsewhere.

2012-07-09net/fsl_pq_mdio: use spin_event_timeout() to poll the indicator registerTimur Tabi
Macro spin_event_timeout() was designed for simple polling of hardware registers with a timeout, so use it when we poll the MIIMIND register. This allows us to return an error code instead of polling indefinitely. Note that PHY_INIT_TIMEOUT is a count of loop iterations, so we can't use it for spin_event_timeout(), which asks for microseconds.

2012-07-09bonding: debugfs and network namespaces are incompatibleEric W. Biederman
The bonding debugfs support has been broken in the presence of network namespaces since it has been added. The debugfs support does not handle multiple bonding devices with the same name in different network namespaces. I haven't had any bug reports, and I'm not interested in getting any. Disable the debugfs support when network namespaces are enabled. Signed-off-by: "Eric W. Biederman" <ebiederm@xmission.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2012-07-09bonding: Manage /proc/net/bonding/ entries from the netdev eventsEric W. Biederman
It was recently reported that moving a bonding device between network namespaces causes warnings from /proc. It turns out after the move we were trying to add and to remove the /proc/net/bonding entries from the wrong network namespace. Move the bonding /proc registration code into the NETDEV_REGISTER and NETDEV_UNREGISTER events where the proc registration and unregistration will always happen at the right time.

For RTL8111G, the settings of phy and firmware are replaced with ocp functions. r8168g_mdio_{write / read} redirects the relative settings to suitable ocp functions. A per-device variable is needed to evaluate the real address of ocp functions. rtl_writephy(tp, 0x1f, xxxx) is dedicated to keeping said variable up-to-date.

2012-07-09stmmac: Fix for higher mtu size handlingDeepak Sikri
For the higher mtu sizes requiring the buffer size greater than 8192, the buffers are sent or received using multiple dma descriptors/ same descriptor with option of multi buffer handling. It was observed during tests that the driver was missing on data packets during the normal ping operations if the data buffers being used catered to jumbo frame handling. The memory barrriers are added in between preparation of dma descriptors in the jumbo frame handling path to ensure all instructions before enabling the dma are complete.

2012-07-09stmmac: Fix for nfs hang on multiple rebootDeepak Sikri
It was observed that during multiple reboots nfs hangs. The status of receive descriptors shows that all the descriptors were in control of CPU, and none were assigned to DMA. Also the DMA status register confirmed that the Rx buffer is unavailable. This patch adds the fix for the same by adding the memory barriers to ascertain that the all instructions before enabling the Rx or Tx DMA are completed which involves the proper setting of the ownership bit in DMA descriptors.

2012-07-09ath9k: Stop the BTCOEX timers before disabling BTCOEXMohammed Shafi Shajakhan
Its safe to stop the BTCOEX timers 'period_timer' and 'no_stomp_timer' before disabling BTCOEX. These timers can call ath9k_hw_btcoex_enable (or) change the BT stomp type if they seem to be running after we had called ath9k_hw_btcoex_disable, which is obviously not correct.

We are doing MCI cleanup eventhough BTCOEX is not enabled via module parameter. This means we do ath_mci_cleanup though we skipped calling ath_mci_setup.
