2014-02-17netdevice: add queue selection fallback handler for ndo_select_queueDaniel Borkmann
Add a new argument for ndo_select_queue() callback that passes a fallback handler. This gets invoked through netdev_pick_tx(); fallback handler is currently __netdev_pick_tx() as most drivers invoke this function within their customized implementation in case for skbs that don't need any special handling. This fallback handler can then be replaced on other call-sites with different queue selection methods (e.g. in packet sockets, pktgen etc). This also has the nice side-effect that __netdev_pick_tx() is then only invoked from netdev_pick_tx() and export of that function to modules can be undone. Suggested-by: David S.

2014-02-14net: asix: add missing flag to struct driver_infoEmil Goode
The struct driver_info ax88178_info is assigned the function asix_rx_fixup_common as it's rx_fixup callback. This means that FLAG_MULTI_PACKET must be set as this function is cloning the data and calling usbnet_skb_return. Not setting this flag leads to usbnet_skb_return beeing called a second time from within the rx_process function in the usbnet module.

phy_init_hw not does a full PHY reset after the driver probe has finished, so any hw initialization done in the probe will be lost. Part of the timestamping functionality of the dp83640 is set up in the probe and with that lost, enabling timestamping will cause a PHY lockup, requiring a hard reset / power cycle to recover.

The only thing that isn't strictly a fix is the 5/10 MHz enabling, I had forgotten this and there's little point in waiting longer. The patch simply removes the force-disable code that I put in when there was a problem with the userspace API (that has long been fixed.)" For the iwlwifi bits, Emmanuel says: "I have an important fix that disables A band in case the driver thought it was enabled, and the firmware disagreed. We ended up making the firmware unhappy. I also fix the station table in AP mode and fix the scan while we have BT working. Johannes removes a static variable that could potentially lead to to issues on multi-device setups and disables scheduled scan to avoid issues with old versions of wpa_supplicant. A small fix from David on scan and a few new device IDs for 7265." On top of that... Oleksij Rempel adds a USB ID to the ar5523 driver and changes the default powersave setting for ath9k_htc to "off", due to observed stability issues (based on an equivalent ath9k patch). Stanislaw Gruszka similarly disables powersave for a couple of rt2x00 drivers. He also fixes a couple of scheduling while atomic issues in ath9k_htc. Sujith Manoharan rounds-out the powersave disables with one for ath9k. He also fixes a build prolem with ath9k on ARM and fixes an ath9k Tx power calculation.

Quoting David Vrabel - "5780 cards cannot have jumbo frames and TSO enabled together. When jumbo frames are enabled by setting the MTU, the TSO feature must be cleared. This is done indirectly by calling netdev_update_features() which will call tg3_fix_features() to actually clear the flags. netdev_update_features() will also trigger a new netlink message for the feature change event which will result in a call to tg3_get_stats64() which deadlocks on the tg3 lock." tg3_set_mtu() does not need to be under the tg3 lock since converting the flags to use set_bit().

2014-02-06rtl8180: Add error check for pci_map_single return value in RX pathandrea.merello
In original code the old RX DMA buffer is unmapped and processed and at the end of the isr a new buffer is mapped with pci_map_single and attached to the RX descriptor. If pci_map_single fails then the RX descriptor remains with no valid DMA buffer attached. In this condition the DMA will target where it shouldn't with obvious evil consequences. Simply avoiding re-arming the descriptor will prevent buggy DMA but it will result soon in RX stuck. This patch move the DMA mapping of the new buffer at the beginning of the ISR (and it adds error check for pci_map_single success/fail). If the DMA mapping fails then we do not unmap the old buffer and we re-arm the descriptor without processing it, with the old DMA buffer still attached. In this way we lose the currently RX-ed packet, but whenever next calls to pci_map_single will succeed again,then the RX process will go on without stuck.

2014-02-05xen-netback: Fix Rx stall due to race conditionZoltan Kiss
The recent patch to fix receive side flow control (11b57f90257c1d6a91cee720151b69e0c2020cf6: xen-netback: stop vif thread spinning if frontend is unresponsive) solved the spinning thread problem, however caused an another one. The receive side can stall, if: - [THREAD] xenvif_rx_action sets rx_queue_stopped to true - [INTERRUPT] interrupt happens, and sets rx_event to true - [THREAD] then xenvif_kthread sets rx_event to false - [THREAD] rx_work_todo doesn't return true anymore Also, if interrupt sent but there is still no room in the ring, it take quite a long time until xenvif_rx_action realize it. This patch ditch that two variable, and rework rx_work_todo. If the thread finds it can't fit more skb's into the ring, it saves the last slot estimation into rx_last_skb_slots, otherwise it's kept as 0. Then rx_work_todo will check if: - there is something to send to the ring (like before) - there is space for the topmost packet in the queue I think that's more natural and optimal thing to test than two bool which are set somewhere else.

2014-02-04xen-netfront: handle backend CLOSED without CLOSINGDavid Vrabel
Backend drivers shouldn't transistion to CLOSED unless the frontend is CLOSED. If a backend does transition to CLOSED too soon then the frontend may not see the CLOSING state and will not properly shutdown. So, treat an unexpected backend CLOSED state the same as CLOSING.

2014-02-04bnx2x: fix L2-GRE TCP issuesDmitry Kravkov
When configuring GRE tunnel using OVS, tcp stream is distributed over all RSS queues which may cause TCP reordering. It happens since OVS uses L2GRE protocol when kernel gre uses IPGRE. Patch defaults gre tunnel to L2GRE which allows proper RSS for L2GRE packets and (implicitly) disables RSS for IPGRE traffic.

2014-02-04net: ethoc: set up MII management bus clockMax Filippov
MII management bus clock is derived from the MAC clock by dividing it by MIIMODER register CLKDIV field value. This value may need to be set up in case it is undefined or its default value is too high (and communication with PHY is too slow) or too low (and communication with PHY is impossible). The value of CLKDIV is not specified directly, but is derived from the MAC clock for the default MII management bus frequency of 2.5MHz. The MAC clock may be specified in the platform data, or in the 'clocks' device tree attribute. Signed-off-by: Max Filippov <jcmvbkbc@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2014-02-04net: ethoc: don't advertise gigabit speed on attached PHYMax Filippov
OpenCores 10/100 Mbps MAC does not support speeds above 100 Mbps, but does not disable advertisement when PHY supports them. This results in non-functioning network when the MAC is connected to a gigabit PHY connected to a gigabit switch. The fix is to disable gigabit speed advertisement on attached PHY unconditionally.

2014-02-04net: phy: ensure Gigabit features are masked off if requestedFlorian Fainelli
When a Gigabit PHY device is connected to a 10/100Mbits capable Ethernet MAC, the driver will restrict the phydev->supported modes to mask off Gigabit. If the Gigabit PHY comes out of reset with the Gigabit features set by default in MII_CTRL1000, it will keep advertising these feature, so by the time we call genphy_config_advert(), the condition on phydev->supported having the Gigabit features on is false, and we do not update MII_CTRL1000 with updated values, and we keep advertising Gigabit features, eventually configuring the PHY for Gigabit whilst the Ethernet MAC does not support that. This patches fixes the problem by ensuring that the Gigabit feature bits are always cleared in MII_CTRL1000, if the PHY happens to be a Gigabit PHY, and then, if Gigabit features are supported, setting those and updating MII_CTRL1000 accordingly.
