      asix: Do full reset during ax88772_bind · 436c2a50
      Charles Keepax authored
      commit 3cc81d85 ("asix: Don't reset PHY on if_up for ASIX 88772")
      causes the ethernet on Arndale to no longer function. This appears to
      be because the Arndale ethernet requires a full reset before it will
      function correctly, however simply reverting the above patch causes
      problems with ethtool settings getting reset.
      
      It seems the problem is that the ethernet is not properly reset during
      bind, and indeed the code in ax88772_bind that resets the device is a
      very small subset of the actual ax88772_reset function. This patch uses
      ax88772_reset in place of the existing reset code in ax88772_bind which
      removes some code duplication and fixes the ethernet on Arndale.
      
      It is still possible that the original patch causes some issues with
      suspend and resume but that seems like a separate issue and I haven't
      had a chance to test that yet.

      net: fec: fix regression on i.MX28 introduced by rx_copybreak support · 1310b544
      Lothar Waßmann authored
      commit 1b7bde6d ("net: fec: implement rx_copybreak to improve rx performance")
      introduced a regression for i.MX28. The swap_buffer() function doing
      the endian conversion of the received data on i.MX28 may access memory
      beyond the actual packet size in the DMA buffer. fec_enet_copybreak()
      does not copy those bytes, so that the last bytes of a packet may be
      filled with invalid data after swapping.
      This will likely lead to checksum errors on received packets.
      E.g. when trying to mount an NFS rootfs:
      UDP: bad checksum. From 192.168.1.225:111 to 192.168.100.73:44662 ulen 36
      
      Do the byte swapping and copying to the new skb in one go if
      necessary.

      ====================
      pull request: wireless 2014-11-06
      
      Please pull this batch of fixes intended for the 3.18 stream...
      
      For the mac80211 bits, Johannes says:
      
      "This contains another small set of fixes for 3.18, these are all
      over the place and most of the bugs are old, one even dates back
      to the original mac80211 we merged into the kernel."
      
      For the iwlwifi bits, Emmanuel says:
      
      "I fix here two issues that are related to the firmware
      loading flow. A user reported that he couldn't load the
      driver because the rfkill line was pulled up while we
      were running the calibrations. This was happening while
      booting the system: systemd was restoring the "disable
      wifi settings" and that raised an RFKILL interrupt during
      the calibration. Our driver didn't handle that properly
      and this is now fixed."
      
      Please let me know if there are problems!

      enic: update desc properly in rx_copybreak · f6b7734b
      Govindarajulu Varadarajan authored
      When we reuse the rx buffer, we need to update the desc. If not hardware sees
      stale value.
      
      In the following crash, when mtu is changed, hardware sees old rx buffer value
      and crashes on skb_put.
      
      Fix this by using enic_queue_rq_desc helper function which updates the necessary
      desc.

      enic: handle error condition properly in enic_rq_indicate_buf · 44aa91ab
      Govindarajulu Varadarajan authored
      In case of error in rx path, we free the buf->os_buf but we do not make it NULL.
      In next iteration we use the skb which is already freed. This causes the
      following crash.

      Eli Cohen authored
      After the EQ is created, it can possibly generate interrupts and the interrupt
      handler is referencing eq->dev. It is therefore required to set eq->dev before
      calling request_irq() so if an event is generated before request_irq() returns,
      we will have a valid eq->dev field.

      net: mv643xx_eth: reclaim TX skbs only when released by the HW · 2c2a9cbd
      Karl Beldan authored
      ATM, txq_reclaim will dequeue and free an skb for each tx desc released
      by the hw that has TX_LAST_DESC set. However, in case of TSO, each
      hw desc embedding the last part of a segment has TX_LAST_DESC set,
      losing the one-to-one 'last skb frag'/'TX_LAST_DESC set' correspondance,
      which causes data corruption.
      
      Fix this by checking TX_ENABLE_INTERRUPT instead of TX_LAST_DESC, and
      warn when trying to dequeue from an empty txq (which can be symptomatic
      of releasing skbs prematurely).
      
      Fixes: 3ae8f4e0 ('net: mv643xx_eth: Implement software TSO')

      This was due to hardware resource sharing conflict with the firmware. This
      patch fixes this crash by using resources (descriptor ring, prefetch buffer)
      that are not shared.

      This patch adds support when used with older firmware (<= 1.13.28).
      
      - Added xgene_ring_mgr_init() to check whether ring manager is initialized
      - Calling xgene_ring_mgr_init() from xgene_port_ops.reset()
      - To handle errors, changed the return type of xgene_port_ops.reset()

      The issue was that the older firmware does not support 10GbE and
      SGMII based 1GBE interfaces.
      
      This patch changes the address length of the reg property of sgmii0 and xgmii
      nodes and serves as preparatory patch for the fix.

      "I fix here two issues that are related to the firmware
      loading flow. A user reported that he couldn't load the
      driver because the rfkill line was pulled up while we
      were running the calibrations. This was happening while
      booting the system: systemd was restoring the "disable
      wifi settings" and that raised an RFKILL interrupt during
      the calibration. Our driver didn't handle that properly
      and this is now fixed."
