      bnx2x: Segregate SR-IOV code · 6411280a
      Ariel Elior authored
      
      
      In this patch the SR-IOV code is segregated from the main bulk of
      the bnx2x code. The CONFIG_BNX2X_SRIOV define is added to Broadcom's
      Kconfig, and allows the elision of the building of all the SR-IOV
      support code in the driver.
      The define is dependant on the kernel CONFIG_PCI_IOV configuration
      define.

      veth: avoid a NULL deref in veth_stats_one · d0e2c55e
      Eric Dumazet authored
      commit 2681128f
      
       (veth: extend device features) added a NULL deref
      in veth_stats_one(), as veth_get_stats64() was not testing if the peer
      device was setup or not.
      
      At init time, we call dev_get_stats() before veth pair is fully setup.

      [  178.934615]  [<ffffffff814dbe22>] sock_sendmsg+0xd2/0xf0
      
      So we must check if peer was setup in veth_get_stats64()
      
      As pointed out by Ben Hutchings, priv->peer is missing proper
      synchronization. Adding RCU protection is a safe and well documented
      way to make sure we don't access about to be freed or already
      freed data.

      Use more current logging styles.
      
      Convert printks to pr_<level> and
      printks with ("%s: ...", dev->name to netdev_<level>(dev, "...
      
      Add pr_fmt #defines where appropriate.
      Coalesce formats.
      Use pr_<level>_once where appropriate.
