Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net
Merge 'net' bug fixes into 'net-next' as we have patches that will build on top of them. This merge commit includes a change from Emil Goode (emilgoode@gmail.com) that fixes a warning that would have been introduced by this merge. Specifically it fixes the pingv6_ops method ipv6_chk_addr() to add a "const" to the "struct net_device *dev" argument and likewise update the dummy_ipv6_chk_addr() declaration. Signed-off-by: David S. Miller <davem@davemloft.net>

+5. RapidIO Bus Attributes
+-------------------------
+
+RapidIO bus subdirectory /sys/bus/rapidio implements the following bus-specific
+attribute:
+
+ scan - allows to trigger enumeration discovery process from user space. This
+ is a write-only attribute. To initiate an enumeration or discovery
+ process on specific mport device, a user needs to write mport_ID (not
+ RapidIO destination ID) into this file. The mport_ID is a sequential
+ number (0 ... RIO_MAX_MPORTS) assigned to the mport device.
+ For example, for a machine with a single RapidIO controller, mport_ID
+ for that controller always will be 0.
+ To initiate RapidIO enumeration/discovery on all available mports
+ a user must write '-1' (or RIO_MPORT_ANY) into this attribute file.
