====================
pull-request: can-next 2015-28-01

this is a pull request of 12 patches for net-next/master.

There are 3 patches by Ahmed S. Darwish, which update the kvaser_usb
driver and add support for the USBcan-II based adapters. Stéphane
Grosjean contributes 7 patches for the peak_usb driver, which add
support for the CANFD USB adapters. I contribute 2 patches which clean
up the peak_usb driver structure a bit.

7866a62104 dev: add per net_device packet type chains
When many pf_packet listeners are created on a lot of interfaces the
current implementation using global packet type lists scales poorly.
This patch adds per net_device packet type lists to fix this problem.

The patch was originally written by Eric Biederman for linux-2.6.29.

7b4ce694b2 rtnetlink: pass link_net to the newlink handler
When IFLA_LINK_NETNSID is used, the netdevice should be built in this link netns
and moved at the end to another netns (pointed by the socket netns or
IFLA_NET_NS_[PID|FD]).

Existing user of the newlink handler will use the netns argument (src_net) to
find a link netdevice or to check some other information into the link netns.
For example, to find a netdevice, two information are required: an ifindex
(usually from IFLA_LINK) and a netns (this link netns).

Note: when using IFLA_LINK_NETNSID and IFLA_NET_NS_[PID|FD], a user may create a
netdevice that stands in netnsX and with its link part in netnsY, by sending a
rtnl message from netnsZ.

NET_ACT_CONNMARK fails to build if NF_CONNTRACK_MARK is disabled,
and d7924450e1 ("act_connmark: Add missing dependency on
NF_CONNTRACK_MARK") fixed that case, but missed the cased where
NF_CONNTRACK is a loadable module.

This adds the second dependency to ensure that NET_ACT_CONNMARK

rather than a loadable module.

 - ACPI support for NXP's pn544 HCI driver. This controller is found on

f5d4abea3c can: kvaser_usb: Add support for the USBcan-II family
CAN to USB interfaces sold by the Swedish manufacturer Kvaser are
divided into two major families: 'Leaf', and 'USBcanII'.  From an
Operating System perspective, the firmware of both families behave
in a not too drastically different fashion.

This patch adds support for the USBcanII family of devices to the
current Kvaser Leaf-only driver.

CAN frames sending, receiving, and error handling paths has been
tested using the dual-channel "Kvaser USBcan II HS/LS" dongle. It
should also work nicely with other products in the same category.

List of new devices supported by this driver update:

         - Kvaser USBcan II HS/HS
         - Kvaser USBcan II HS/LS
         - Kvaser USBcan Rugged ("USBcan Rev B")
         - Kvaser Memorator HS/HS
         - Kvaser Memorator HS/LS

The implementation takes into consideration for future expansion in Quark

ef0223e693 net/mlx4_core: Remove duplicate code line from procedure mlx4_bf_alloc
mlx4_bf_alloc had an unnecessary/duplicate code line. Did no harm,
but not good practice.

dc7d500451 net/mlx4_core: Fix struct mlx4_vhcr_cmd to make implicit padding explicit
Struct mlx4_vhcr was implicitly padded by the gcc compiler on 64-bit
architectures.

This commit makes that padding explicit, to prevent issues with
changing compilers and with incompatibilities between 32-bit architecture
implicit padding and 64-bit architecture implicit padding.

This structure is used in virtualization for communication between
the Host and its Guests. The explicit padding allows 64-bit Hosts
(old and new) to continue to interoperate with 64-bit Guests (old and new).

However, without this fix, 64-bit Hosts could not interoperate with 32-bit
Guests (since these did not insert the padding dword). With this fix,
32-bit Guests will be able to interoperate with 64-bit Hosts (since
the structure offsets will be identical on both).

30a5da5b33 net/mlx4_core: Fix HW2SW_EQ to conform to the firmware spec
The driver incorrectly assigned an out-mailbox to this command,
and used an opcode modifier = 0, which is a reserved value (it

5a03108689 net/mlx4_core: Adjust command timeouts to conform to the firmware spec
The firmware spec states that the timeout for all commands should be 60 seconds.

In the past, the spec indicated that there were several classes of timeout
(short, medium, and long).  The driver has these different timeout classes.
We leave the class differentiation in the driver as-is (to protect against any
future spec changes), but set the timeout for all classes to be 60 seconds.

In addition, we fix a few commands which had hard-coded numeric timeouts specified.

f0ce061508 net/mlx4_core: Add reserved lkey for VFs to QUERY_FUNC_CAP
The reserved lKey is different for each VF.
A base lkey value is returned in QUERY_DEV_CAP at offset 0x98.

The reserved L_key value for a VF is:
    VF_lkey = base_lkey + (VF_number << 8).

This VF L_key value should be returned in QUERY_FUNC_CAP
(opcode-modifier = 0) at offset 0x48.

To indicate that the lkey value at offset 0x48 is valid, the Hypervisor
sets a flag bit in dword 0x0, offset 27 in the QUERY_FUNC_CAP wrapper
function.

When the VF calls QUERY_FUNC_CAP, it should check if this flag bit is set.
If it is set, the VF should take the reserved lkey value at offset 0x48.
If the bit is not set, the VF should not use a reserved lkey
(i.e., should set its reserved lkey value to 0).

4967082b46 vxlan: advertise link netns in fdb messages
Previous commit is based on a wrong assumption, fdb messages are always sent
into the netns where the interface stands (see vxlan_fdb_notify()).

These fdb messages doesn't embed the rtnl attribute IFLA_LINK_NETNSID, thus we
need to add it (useful to interpret NDA_IFINDEX or NDA_DST for example).

Note also that vxlan_nlmsg_size() was not updated.

Jonathan Toppins says:

====================
bonding: various 802.3ad fixes

This patch series is a forward porting of patches we (Cumulus) are shipping
in our 3.2 series kernels. These fixes attempt to make 802.3ad bonding mode
more predictable in certian state machine transtions in addition to fixing
802.3ad bond carrier determination when bonding min_links option is changed.
Specific notes are contained within each patch.

For this patch series there are no userspace facing changes, a diff between
the modinfo output showed no difference. However, there are behavioral
facing changes, primarily in the bond carrier state. Please make sure to
review carefully.

v2:
 * fixed some style issues
 * dropped a portion of patch 1 in favor of more testing on my side

2f6373245a bonding: fix LACP PDU not sent on slave port sometimes
When a slave is added to a bond and it is not in full duplex mode,
AD_PORT_LACP_ENABLED flag is cleared, due to this LACP PDU is not sent
on slave. When the duplex is changed to full, the flag needs to be set
to send LACP PDU.

63b46242f7 bonding: fix incorrect lacp mux state when agg not active
This patch attempts to fix the following problems when an actor or
partner's aggregator is not active:
    1. a slave's lacp port state is marked as AD_STATE_SYNCHRONIZATION
       even if it is attached to an inactive aggregator. LACP advertises
       this state to the partner, making the partner think he can move
       into COLLECTING_DISTRIBUTING state even though this link will not
       pass traffic on the local side

    2. a slave goes into COLLECTING_DISTRIBUTING state without checking
       if the aggregator is actually active

    3. when in COLLECTING_DISTRIBUTING state, the partner parameters may
       change, e.g. the partner_oper_port_state.SYNCHRONIZATION. The
       local mux machine is not reacting to the change and continue to
       keep the slave and bond up

    4. When bond slave leaves an inactive aggregator and joins an active
       aggregator, the actor oper port state need to update to SYNC state.

v2:
 * fix style issues in bond_3ad.c

8bbe71a595 bonding: fix bond_open() don't always set slave active flag
Mode 802.3ad, fix incorrect bond slave active state when slave is not in
active aggregator. During bond_open(), the bonding driver always sets
the slave active flag to true if the bond is not in active-backup, alb,
or tlb modes. Bonding should let the aggregator selection logic set the
active flag when in 802.3ad mode.
