      vxlan: Fix to enable UDP checksums on interface · 5c91ae08
      Tom Herbert 提交于
      Add definition to vxlan nla_policy for UDP checksum. This is necessary
      to enable UDP checksums on VXLAN.
      
      In some instances, enabling UDP checksums can improve performance on
      receive for devices that return legacy checksum-unnecessary for UDP/IP.
      Also, UDP checksum provides some protection against VNI corruption.
      
      Testing:
      
      Ran 200 instances of TCP_STREAM and TCP_RR on bnx2x.
      
      TCP_STREAM
        IPv4, without UDP checksums
            14.41% TX CPU utilization
            25.71% RX CPU utilization
            9083.4 Mbps
        IPv4, with UDP checksums
            13.99% TX CPU utilization
            13.40% RX CPU utilization

      amd-xgbe: AMD XGBE driver updates 2014-11-06
      
      The following series of patches fixes a couple of bugs that slipped
      through my last series.
      
      - Free channel structure after freeing the per channel interrupts
      - If an skb error allocation occurs during receive processing check
        whether more descriptors are associated with the packet or whether
        to start on a new packet
      
      This patch series is based on net-next.

      Lendacky, Thomas 提交于
      If the skb allocation fails during receive processing, the driver would
      continue reading descriptors without first determining if there were
      any more descriptors for the current packet. Update the code to check
      whether more descriptors are associated with the current packet or
      whether to move on to the next descriptor as a new packet.

      enic: update desc properly in rx_copybreak · f6b7734b
      Govindarajulu Varadarajan 提交于
      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.

      sunvnet: bug fixes
      
      This patch series has a coding-style fix and a bug fix.
      
      The coding style fix (patch 1) is the extra indentation flagged by
      Ben Hutchings:
        http://marc.info/?l=linux-netdev&m=141529243409594&w=2
      
      The bugfix (patch 2) is the following:
      when vnet_event_napi() is  called as part of napi_resume
      (i.e., continuation of a previous NAPI read that was truncated
      due to budget constraints), and then finds no more packets to read,
      the code was trying to avoid an additional trip through ldc_rx
      as an optimization. However, when this corner case happens, we would
      need to reset a number of dring state bits such as rcv_nxt carefully,
      which quickly becomes complex and hacky.  The cleaner solution
      is to just roll back to vnet_poll, re-enable interrupts and set up
      dring state as was done in the pre-NAPI version of the driver.

      sunvnet: Return from vnet_napi_event() if no packets to read · 8c4ee3e7
      Sowmini Varadhan 提交于
      vnet_event_napi() may be called as part of the NAPI ->poll,
      to resume reading descriptor rings. When no data is available,
      descriptor ring state (e.g., rcv_nxt) needs to be reset
      carefully to stay in lock-step with ldc_read(). In the interest
      of simplicity, the best way to do this is to return from
      vnet_event_napi() when there are no more packets to read.
      The next trip through ldc_rx will correctly set up the dring state.

      Then, the rtl_ops_init() could use tp->version.

      net: esp: Convert NETDEBUG to pr_info · 45083497
      Joe Perches 提交于
      Commit 64ce2073 ("[NET]: Make NETDEBUG pure printk wrappers")
      originally had these NETDEBUG printks as always emitting.
      
      Commit a2a316fd ("[NET]: Replace CONFIG_NET_DEBUG with sysctl")
      added a net_msg_warn sysctl to these NETDEBUG uses.
      
      Convert these NETDEBUG uses to normal pr_info calls.
      
      This changes the output prefix from "ESP: " to include
      "IPSec: " for the ipv4 case and "IPv6: " for the ipv6 case.
      
      These output lines are now like the other messages in the files.
      
      Other miscellanea:
      
      Neaten the arithmetic spacing to be consistent with other
      arithmetic spacing in the files.

      net: mv643xx_eth: reclaim TX skbs only when released by the HW · 2c2a9cbd
      Karl Beldan 提交于
      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).
