fa00e8fed4 NFC: nci: Move NFCEE discovery logic
NFCEE_DISCOVER_CMD is a specified NCI command used to discover
NFCEE IDs.
Move nci_nfcee_discover() call to nci_discover_se() in order to
guarantee:
- NFCEE_DISCOVER_CMD run when the NCI state machine is initialized
- NFCEE_DISCOVER_CMD is not run in case there is not discover_se
  hook defined by a NFC device driver.

b16ae7160a NFC: nci: Support all destinations type when creating a connection
The current implementation limits nci_core_conn_create_req()
to only manage NCI_DESTINATION_NFCEE.
Add new parameters to nci_core_conn_create() to support all
destination types described in the NCI specification.
Because there are some parameters with variable size dynamic

8ae01f7967 NFC: st21nfcb: Add support for secure element
The st21nfcb chipset has 3 SWP (Single Wire Protocol) lines and
supports up to 3 secure elements (UICC/eSE and µSD in the future).

Some st21nfcb firmware does not support the nci command
nci_nfcee_mode_set(NCI_NFCEE_DISABLE). For this reason, we assume
2 secures elements are always present (UICC and eSE).
They will be added to the SE list once successfully activated and
they will be available only after running through enable_se
handler or when the poll in listen mode is started.

During initialization, the white_list will be always set assuming
both UICC & eSE are present.

On eSE activation, the ATR bytes are fetched to build the command
exchange timeout.

The se_io hook will allow to transfer data over SWP. 2 kind of
events may appear data is sent over:
- ST21NFCB_EVT_TRANSMIT_DATA when receiving an apdu answer
- ST21NFCB_EVT_WTX_REQUEST when the secure element needs more time
  than expected to process a command. If this timeout expires, we
  send a software reset, and then a hardware one if it still fails.

11f54f2286 NFC: nci: Add HCI over NCI protocol support
According to the NCI specification, one can use HCI over NCI
to talk with specific NFCEE. The HCI network is viewed as one
logical NFCEE.
This is needed to support secure element running HCI only
firmwares embedded on an NCI capable chipset, like e.g. the
st21nfcb.
There is some duplication between this piece of code and the
HCI core code, but the latter would need to be abstracted even
more to be able to use NCI as a logical transport for HCP packets.

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).

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.
