      netns: Fix crash by making igmp per namespace · 877acedc
      Daniel Lezcano authored
      This patch makes the multicast socket to be per namespace.
      
      When a network namespace is created, other than the init_net and a
      multicast packet is received, the kernel goes to a hang or a kernel panic.
      
      How to reproduce ?
      
       * create a child network namespace
       * create a pair virtual device veth
          * ip link add type veth
       * move one side to the pair network device to the child namespace
          * ip link set netns <childpid> dev veth1
       * ping -I veth0 224.0.0.1
      
      The bug appears because the function ip_mc_init_dev does not initialize
      the different multicast fields as it exits because it is not the init_net.

      Minor code improvements
      Small changes to make the code a little bit more efficient and mostly
      more readable:
      - Using unified macros for EMAC_RD/WR which looks like normal REG_RD/WR
      - Removing the NIG_WR since it did nothing and was only confusing
      - On bnx2x_panic_dump, print only the used parts of the rings
      - define parameters only on the branch they are needed and not at the
        beginning of the function
      - using NETIF_MSG_INTR and not private BNX2X_MSG_SP for debug prints

      The internal FW which is downloaded by the driver should not be
      displayed - it is only causing confusion and it is redundant since it
      can be concluded from the driver version. Display only FW which is
      burned on the board nvram

      8073 PHY changes
      The initial support we had for this PHY needs some serious changing. The
      major change is that this PHY should be initialized only when the first
      function is loaded and not for each function. The official SPI-ROM of
      this PHY was released and it requires some changes in the initialization
      code as well

      Change GPIO for any port
      The set GPIO function should receive the port index to allow changing
      the GPIO of another port. This is needed for the common init phase (one
      the first driver is loaded for the chip)

      bnx2x: Pause settings · 8c99e7b0
      Yaniv Rosner authored
      Pause settings
      - 1G pause was not working due to missing write to the emac block
        (TX_MODE_FLOW_EN)
      - The flow control should use the negotiated result (after autoneg) so
        we should save both the requested autoneg and the result
      - The HW credits with flow control at 1G speed were not optimized and
        caused low throughput
      - It is recommended to turn off flow control if the MTU is bigger than
        5000B due to internal buffers size
