Currently, the network interfaces that are not configured by the bootloader (using e.g. tftp or ping) can detect the link status but are unable to transmit data. The network controller has a functionality that allows the hardware to continuously poll the PHY and directly update the MAC configuration accordingly (speed, duplex, etc.). However, this doesn't work well with phylib's software-based polling and updating MAC configuration in the driver's callback. This commit fixes this issue by: 1. Setting MVPP2_PHY_AN_STOP_SMI0_MASK in MVPP2_PHY_AN_CFG0_REG in mvpp2_init(), which disables the harware polling feature. 2. Disabling MVPP2_GMAC_PCS_ENABLE_MASK bit in MVPP2_GMAC_CTRL_2_REG in mvpp2_port_mii_set() for port types other than SGMII. Signed-off-by:

The check for Nagle contains 6 separate checks all of which must be true before a data packet is delayed. Separate out each into its own 'if (test) return SCTP_XMIT_OK' so that the reasons can be individually described. Also return directly with SCTP_XMIT_RWND_FULL. Delete the now-unused 'retval' variable and 'finish' label from sctp_packet_can_append_data(). Signed-off-by:

He converted that clock to use jiffies_64 and made it into a counter instead of nanosecond conversions, and displayed the clock with the straight jiffy count, which works much better than it did in the past" * tag 'trace-fixes-v3.16-rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace: tracing: Fix wraparound problems in "uptime" trace clock

An af_iucv stress test showed -EPIPE results for sendmsg() calls. They are caused by quiescing a path even though it has been already severed by peer. For IUCV transport shutdown() consists of 2 steps: (1) sending the shutdown message to peer (2) quiescing the iucv path If the iucv path between these 2 steps is severed due to peer closing the path, the quiesce step is no longer needed.

Antonio Quartulli says: ==================== pull request [net]: batman-adv 20140721 here you have two fixes that we have been testing for quite some time (this is why they arrived a bit late in the rc cycle). Patch 1) ensures that BLA packets get dropped and not forwarded to the mesh even if they reach batman-adv within QinQ frames. Forwarding them into the mesh means messing up with the TT database of other nodes which can generate all kind of unexpected behaviours during route computation. Patch 2) avoids a couple of race conditions triggered upon fast VLAN deletion-addition. Such race conditions are pretty dangerous because they not only create inconsistencies in the TT database of the nodes in the network, but such scenario is also unrecoverable (unless nodes are rebooted). ==================== Signed-off-by:

bcmgenet_wol_resume() will create an unbalanced clock state for the wol_clk clock pointer since everywhere else in the code, we always call clk_prepare_enable() and clk_disable_unprepare(). This function also calls init_umac() which is neither correct nor necessary since bcmgenet_resume() and bcmgenet_open() already does that. Finally calling bcmgenet_wol_resume() in bcmgenet_open() is not correct, since the interface would not have been able to put us in Wake-on-LAN mode if it was not UP before. Signed-off-by:
