6f89062a66 b43: bcma: drop BROKEN
We've fixed the last issue with BCMA support which caused memory
corruption on loading and unloading b43. Support for BCMA in b43 was
tested with 14e4:4353, 14e4:4357, 14e4:4727 and 14e4:4331. First two
cards (BCM43224 and BCM43225) are supported.

a203c2aa4c cfg80211: really ignore the regulatory request
At the beginning of wiphy_update_regulatory() a check is performed
whether the request is to be ignored. Then the request is sent to
the driver nevertheless. This happens even if last_request points
to NULL, leading to a crash in the driver:

9417c464ba ixgbe: only enable WoL for magic packet by default
Martin Wilck <martin.wilck@ts.fujitsu.com> reported that systems using
the ixgbe-driver that were capable of WoL were rebooting almost as soon
as they were shut down.  This is because the default WoL settings
enabled magic packet, broadcast, unicast, and multicast.

Other Intel devices seem to use the stored eeprom value for initial WoL
capabilities.  The 82578DM (e1000e) and 82576 (igb) the devices I looked
at had only the magic packet enabled in the eeprom, so that seems
appropriate on ixgbe-based devices as well.  I set the WoL options on my
82578DM to be the same default as the ixgbe devices (umbg) and saw the
same as Martin -- almost as soon as my box shutdown, it booted again.

This patch changes the default to only be the magic packet.  This is the
same as the default for most Intel and non-Intel hardware currently
upstream.

bd19805803 ixgbe: Move interrupt related values out of ring and into q_vector
This change moves work_limit, total_packets, and total_bytes into the ring
container struct of the q_vector.  The advantage of this is that it should
reduce the size of memory used in the event of multiple rings being
assigned to a single q_vector.  In addition it should help to reduce the
total workload for calculating itr since now total_packets and total_bytes
will be the total work done of the interrupt instead of for the ring.

08c8833b29 ixgbe: add structure for containing RX/TX rings to q_vector
This patch adds support for a ring container structure to be used within
the q_vector.  The basic idea is to provide a means of separating the RX

The advantage to this is that later we should be able to pass this
structure to the update_itr functions without needing to pass individual
rings.

87c48fa3b4 ipv6: make fragment identifications less predictable
IPv6 fragment identification generation is way beyond what we use for
IPv4 : It uses a single generator. Its not scalable and allows DOS
attacks.

Now inetpeer is IPv6 aware, we can use it to provide a more secure and
scalable frag ident generator (per destination, instead of system wide)

This patch :
1) defines a new secure_ipv6_id() helper
2) extends inet_getid() to provide 32bit results
3) extends ipv6_select_ident() with a new dest parameter

icmp6_dst_alloc() must set rt6i_dst before calling dst_metric_set(), or
else the cow is done while rt6i_dst is still NULL.

If orig route points to readonly metrics, we can share the pointer
instead of performing the memory allocation and copy.

36bcfe7d74 stmmac: unify MAC and PHY configuration parameters (V2)
Prior to this change, most PHY configuration parameters were passed
into the STMMAC device as a separate PHY device. As well as being
unusual, this made it difficult to make changes to the MAC/PHY
relationship.

This patch moves all the PHY parameters into the MAC configuration
structure, mainly as a separate structure. This allows us to completely
ignore the MDIO bus attached to a stmmac if desired, and not create
the PHY bus. It also allows the stmmac driver to use a different PHY
from the one it is connected to, for example a fixed PHY or bit banging
PHY.

Also derive the stmmac/PHY connection type (MII/RMII etc) from the
mode can be passed into <platf>_configure_ethernet.
STLinux kernel at git://git.stlinux.com/stm/linux-sh4-2.6.32.y.git
provides several examples how to use this new infrastructure (that
actually is easier to maintain and clearer).

67ae7cf1ee ethtool: Allow zero-length register dumps again
Some drivers (ab)use the ethtool_ops::get_regs operation to expose
only a hardware revision ID.  Commit
a77f5db361 ('ethtool: Allocate register
dump buffer with vmalloc()') had the side-effect of breaking these, as
vmalloc() returns a null pointer for size=0 whereas kmalloc() did not.

For backward-compatibility, allow zero-length dumps again.
