      netlink: use <linux/export.h> instead of <linux/module.h> · abb17e6c
      Pablo Neira Ayuso authored
      Since (9f00d977 netlink: hide struct module parameter in netlink_kernel_create),
      linux/netlink.h includes linux/module.h because of the use of THIS_MODULE.
      
      Use linux/export.h instead, as suggested by Stephen Rothwell, which is
      significantly smaller and defines THIS_MODULES.

      Commit eb716c54 ("sunbmac: remove
      unnecessary setting of skb->dev") caused the local varible 'dev'
      in bigmac_init_rings to become unused.  And now the compiler

      On some hw, link is not up during adding iface to team. That causes event

      ipconfig: add nameserver IPs to kernel-parameter ip= · 5e953778
      Christoph Fritz authored
      On small systems (e.g. embedded ones) IP addresses are often configured
      by bootloaders and get assigned to kernel via parameter "ip=".  If set to
      "ip=dhcp", even nameserver entries from DHCP daemons are handled. These
      entries exported in /proc/net/pnp are commonly linked by /etc/resolv.conf.
      
      To configure nameservers for networks without DHCP, this patch adds option
      <dns0-ip> and <dns1-ip> to kernel-parameter 'ip='.

      net: qmi_wwan: adding Huawei E367, ZTE MF683 and Pantech P4200 · 42d94dcb
      Bjørn Mork authored
      One of the modes of Huawei E367 has this QMI/wwan interface:
      
       I:* If#= 1 Alt= 0 #EPs= 3 Cls=ff(vend.) Sub=01 Prot=07 Driver=(none)
       E:  Ad=83(I) Atr=03(Int.) MxPS=  64 Ivl=2ms
       E:  Ad=84(I) Atr=02(Bulk) MxPS= 512 Ivl=0ms
       E:  Ad=02(O) Atr=02(Bulk) MxPS= 512 Ivl=4ms
      
      Huawei use subclass and protocol to identify vendor specific
      functions, so adding a new vendor rule for this combination.
      
      The Pantech devices UML290 (106c:3718) and P4200 (106c:3721) use
      the same subclass to identify the QMI/wwan function.  Replace the
      existing device specific UML290 entries with generic vendor matching,
      adding support for the Pantech P4200.
      
      The ZTE MF683 has 6 vendor specific interfaces, all using
      ff/ff/ff for cls/sub/prot.  Adding a match on interface #5 which
      is a QMI/wwan interface.

      USB: remove dbg() usage in USB networking drivers · 49ae25b0
      Greg Kroah-Hartman authored
      The dbg() USB macro is so old, it predates me.  The USB networking drivers are
      the last hold-out using this macro, and we want to get rid of it, so replace
      the usage of it with the proper netdev_dbg() or dev_dbg() (depending on the
      context) calls.
      
      Some places we end up using a local variable for the debug call, so also
      convert the other existing dev_* calls to use it as well, to save tiny amounts
      of code space.

      	tcp_parse_options
      
      However if they are fed a frame containing a TCP_SACK then tbe code
      behaviour is undefined because opt_rx->sack_ok is undefined data.

      IB/ipoib: Add rtnl_link_ops support · 9baa0b03
      Or Gerlitz authored
      Add rtnl_link_ops to IPoIB, with the first usage being child device
      create/delete through them. Childs devices are now either legacy ones,
      created/deleted through the ipoib sysfs entries, or RTNL ones.
      
      Adding support for RTNL childs involved refactoring of ipoib_vlan_add
      which is now used by both the sysfs and the link_ops code.
      
      Also, added ndo_uninit entry to support calling unregister_netdevice_queue
      from the rtnl dellink entry. This required removal of calls to
      ipoib_dev_cleanup from the driver in flows which use unregister_netdevice,
      since the networking core will invoke ipoib_uninit which does exactly that.

      which will mean that the VF is capable of cleaning up buffers that span

      Alexander Duyck authored
      For some reason the reading of the RQDPC register was being artificially
      limited to 4K.  Instead of limiting the value we should read the value and
      add the full amount.  Otherwise this can lead to a misleading number of
      dropped packets when the actual value is in fact much higher.
