      e1000e: workaround invalid Tx/Rx tail descriptor register write · c6e7f51e
      Bruce Allan authored
      When the Manageability Engine (ME) is enabled on 82579, it periodically
      accesses some MAC CSR registers.  There is an arbiter in hardware which
      prevents simultaneous access of these registers by the host software, i.e.
      the driver.  There is a hardware bug in the aribter that signals a host
      access of the registers later than it actually happens.  A write of the
      Transmit or Receive Descriptor Tail register could result in an incorrect
      value if the driver and ME perform simultaneous accesses which could result
      in an access to an invalid memory address.  This would return an
      Unsupported Request which could hang the hardware.  Workaround the issue by
      checking the FWSM register bit24 which is set by ME before it accesses the
      MAC CSR registers.

      e1000e: workaround for packet drop on 82579 at 100Mbps · 0ed013e2
      Bruce Allan authored
      The MAC can drop short packets when the PHY detects noise on the line at
      100Mbps due to a timing issue.  Workaround the issue by increasing the PLL
      counter so the PHY properly recognizes the synchronization pattern from the
      MAC.

      e1000e: Spurious interrupts & dropped packets with 82577/8/9 in half-duplex · 1d2101a7
      Bruce Allan authored
      On 82577/8/9 in half-duplex when a received packet is passed from the PHY
      to the MAC, if too many preamble octects are stripped from the packet
      before arriving at the MAC, it can be misintrepeted as an in-band message
      rather than an actual frame.  For example, if the frame contents resembled
      an interrupt request in-band message, it would trigger a false interrupt.
      In most cases, the packet is just dropped.
      
      By reducing the number of preamble octets stripped from the beginning of
      the frame when passing it from the PHY to the MAC, the MAC will interpret
      the frame properly.
      
      An additional uses of the magic PHY_REG(770, 16) have been updated with a
      define introduced with this patch.

      ixgbe: Fix FCOE memory leak for DDP packets · 63d635b2
      Alexander Duyck authored
      This patch is meant to fix a memory leak found via code review for FCOE.
      Specifically on DDP flows the SKBs were being dropped without being
      recycled, freed, or given to the stack.
