net: qualcomm: rmnet: Updates 2018-03-12

This series contains some minor updates for rmnet driver.

Patch 1 contains fixes for sparse warnings.
Patch 2 updates the copyright date to 2018.
Patch 3 is a cleanup in receive path.
Patch 4 has the new rmnet netlink attributes in uapi and updates the usage.
Patch 5 has the implementation of the fill_info operation.

v1->v2: Remove the force casts since the data type is changed to __be
types as mentioned by David.
v2->v3: Update copyright in files which actually had changes as
mentioned by Joe.
v3->v4: Add new netlink attributes for mux_id and flags instead of using the
the vlan attributes as mentioned by David. The rmnet specific flags are also
moved to uapi. The netlink updates are done as part of #4 and #5 has the
fill_info operation.

tipc: socket diagnostics additions for AF_TIPC

The following patchsets add socket diagnostics support for AF_TIPC by
using the sock diag framework. The patchset was created on top of
commit id: fb66cb07.

New iproute2 package is needed to use this functionality which will
be sent for review in a seperate mail.

The commit series improves diagnosis of tipc sockets by exporting the
configuration, states and statistics of sockets.

The series has been co-authored by Parthasarathy Bhuvaragan and
consist of two parts:

1-2:  Adaptations of existing code to support sock_diag framework.
We modify existing functions to support socket diagnostics. Required
information about the sockets are exported.

3:  Step sk_drops during packet drop.
This occurs if the packet cannot be queued due to queue length exceeding
configured thresholds.

The diag module is optional, and if enabled it will be loaded on demand
when needed.

Currently when tipc is unable to queue a received message on a
socket, the message is rejected back to the sender with error
TIPC_ERR_OVERLOAD. However, the application on this socket
has no knowledge about these discards.

In this commit, we try to step the sk_drops counter when tipc
is unable to queue a received message. Export sk_drops
using tipc socket diagnostics.

This commit adds socket diagnostics capability for AF_TIPC in netlink
family NETLINK_SOCK_DIAG in a new kernel module (diag.ko).

The following are key design considerations:
- config TIPC_DIAG has default y, like INET_DIAG.
- only requests with flag NLM_F_DUMP is supported (dump all).
- tipc_sock_diag_req message is introduced to send filter parameters.
- the response attributes are of TLV, some nested.

To avoid exposing data structures between diag and tipc modules and
avoid code duplication, the following additions are required:
- export tipc_nl_sk_walk function to reuse socket iterator.
- export tipc_sk_fill_sock_diag to fill the tipc diag attributes.
- create a sock_diag response message in __tipc_add_sock_diag defined
  in diag.c and use the above exported tipc_sk_fill_sock_diag
  to fill response.

The current socket iterator function tipc_nl_sk_dump, handles socket
locks and calls __tipc_nl_add_sk for each socket.
To reuse this logic in sock_diag implementation, we do minor
modifications to make these functions generic as described below.

In this commit, we add a two new functions __tipc_nl_sk_walk,
__tipc_nl_add_sk_info and modify tipc_nl_sk_dump, __tipc_nl_add_sk
accordingly.

In __tipc_nl_sk_walk we:
1. acquire and release socket locks
2. for each socket, execute the specified callback function

In __tipc_nl_add_sk we:
- Move the netlink attribute insertion to __tipc_nl_add_sk_info.

tipc_nl_sk_dump calls tipc_nl_sk_walk with __tipc_nl_add_sk as argument.

sock_diag will use these generic functions in a later commit.

There is no functional change in this commit.

When changing the mtu, the max frame size also will be changed. The tx
buffer size and the rx buffer size to be allocated are determined by max
frame size. So when max frame size is changed, the tx buffer and rx buffer
need to be reallocated.
