      fsl_etsec: Fix Tx BD ring wrapping handling · 7e354ed4
      Andrey Smirnov 提交于
      Current code that handles Tx buffer desciprtor ring scanning employs the
      following algorithm:
      
      	1. Restore current buffer descriptor pointer from TBPTRn
      
      	2. Process current descriptor
      
      	3. If current descriptor has BD_WRAP flag set set current
      	   descriptor pointer to start of the descriptor ring
      
      	4. If current descriptor points to start of the ring exit the
      	   loop, otherwise increment current descriptor pointer and go
      	   to #2
      
      	5. Store current descriptor in TBPTRn
      
      The way the code is implemented results in buffer descriptor ring being
      scanned starting at offset/descriptor #0. While covering 99% of the
      cases, this algorithm becomes problematic for a number of edge cases.
      
      Consider the following scenario: guest OS driver initializes descriptor
      ring to N individual descriptors and starts sending data out. Depending
      on the volume of traffic and probably guest OS driver implementation it
      is possible that an edge case where a packet, spread across 2
      descriptors is placed in descriptors N - 1 and 0 in that order(it is
      easy to imagine similar examples involving more than 2 descriptors).
      
      What happens then is aforementioned algorithm starts at descriptor 0,
      sees a descriptor marked as BD_LAST, which it happily sends out as a
      separate packet(very much malformed at this point) then the iteration
      continues and the first part of the original packet is tacked to the
      next transmission which ends up being bogus as well.
      
      This behvaiour can be pretty reliably observed when scp'ing data from a
      guest OS via TAP interface for files larger than 160K (every time for
      700K+).
      
      This patch changes the scanning algorithm to do the following:
      
      	1. Restore "current" buffer descriptor pointer from
      	   TBPTRn
      
      	2. If "current" descriptor does not have BD_TX_READY set, goto #6
      
      	3. Process current descriptor
      
      	4. If "current" descriptor has BD_WRAP flag set "current"
      	   descriptor pointer to start of the descriptor ring otherwise
      	   set increment "current" by the size of one descriptor
      
      	5. Goto #1
      
      	6. Save "current" buffer descriptor in TBPTRn
      
      This way we preserve the information about which descriptor was
      processed last and always start where we left off avoiding the original
      problem. On top of that, judging by the following excerpt from
      MPC8548ERM (p. 14-48):
      
      "... When the end of the TxBD ring is reached, eTSEC initializes TBPTRn
      to the value in the corresponding TBASEn. The TBPTR register is
      internally written by the eTSEC’s DMA controller during
      transmission. The pointer increments by eight (bytes) each time a
      descriptor is closed successfully by the eTSEC..."
      
      revised algorithm might also a more correct way of emulating this aspect
      of eTSEC peripheral.

      Hervé Poussineau 提交于
      According to datasheet:
      "[Bit 15 of Basic Mode Control Register] sets the status and control registers
      of the PHY (register 0062-0074) in a default state. This bit is self-clearing.
      1 = software reset; 0 = normal operation."
      
      This fixes the netcard detection failure in Minoca OS.

      record/replay: add network support · 646c5478
      Pavel Dovgalyuk 提交于
      This patch adds support of recording and replaying network packets in
      irount rr mode.
      
      Record and replay for network interactions is performed with the network filter.
      Each backend must have its own instance of the replay filter as follows:
       -netdev user,id=net1 -device rtl8139,netdev=net1
       -object filter-replay,id=replay,netdev=net1
      
      Replay network filter is used to record and replay network packets. While
      recording the virtual machine this filter puts all packets coming from
      the outer world into the log. In replay mode packets from the log are
      injected into the network device. All interactions with network backend
      in replay mode are disabled.
      
      v5 changes:
       - using iov_to_buf function instead of loop
