      hv_netvsc: Wait for sub-channels to be processed during probe · b3e6b82a
      KY Srinivasan authored 
      The current code returns from probe without waiting for the proper handling
of subchannels that may be requested. If the netvsc driver were to be rapidly
loaded/unloaded, we can  trigger a panic as the unload will be tearing
down state that may not have been fully setup yet. We fix this issue by making
sure that we return from the probe call only after ensuring that the
sub-channel offers in flight are properly handled.

      cxgb4: Allow firmware flash, only if cxgb4 is the master driver · 402b7645
      Hariprasad Shenai authored 
      Adapter can go for a toss, if cxgb4 is loaded as slave and we try to
upgrade the firmware. So add a check for the same before flashing
firmware using ethtool.

tipc: clean up socket message reception

Despite recent improvements the message reception code in socket.c is
perceived as obscure and hard to follow, especially regarding the logics
for message rejection. With the commits in this series we try to remedy
this situation.

      tipc: clean up socket layer message reception · cda3696d
      Jon Paul Maloy authored 
      When a message is received in a socket, one of the call chains
tipc_sk_rcv()->tipc_sk_enqueue()->filter_rcv()(->tipc_sk_proto_rcv())
or
tipc_sk_backlog_rcv()->filter_rcv()(->tipc_sk_proto_rcv())
are followed. At each of these levels we may encounter situations
where the message may need to be rejected, or a new message
produced for transfer back to the sender. Despite recent
improvements, the current code for doing this is perceived
as awkward and hard to follow.

Leveraging the two previous commits in this series, we now
introduce a more uniform handling of such situations. We
let each of the functions in the chain itself produce/reverse
the message to be returned to the sender, but also perform the
actual forwarding. This simplifies the necessary logics within
each function.

      tipc: introduce new tipc_sk_respond() function · bcd3ffd4
      Jon Paul Maloy authored 
      Currently, we use the code sequence

if (msg_reverse())
   tipc_link_xmit_skb()

at numerous locations in socket.c. The preparation of arguments
for these calls, as well as the sequence itself, makes the code
unecessarily complex.

In this commit, we introduce a new function, tipc_sk_respond(),
that performs this call combination. We also replace some, but not
yet all, of these explicit call sequences with calls to the new
function. Notably, we let the function tipc_sk_proto_rcv() use
the new function to directly send out PROBE_REPLY messages,
instead of deferring this to the calling tipc_sk_rcv() function,
as we do now.

      tipc: let function tipc_msg_reverse() expand header when needed · 29042e19
      Jon Paul Maloy authored 
      The shortest TIPC message header, for cluster local CONNECTED messages,
is 24 bytes long. With this format, the fields "dest_node" and
"orig_node" are optimized away, since they in reality are redundant
in this particular case.

However, the absence of these fields leads to code inconsistencies
that are difficult to handle in some cases, especially when we need
to reverse or reject messages at the socket layer.

In this commit, we concentrate the handling of the absent fields
to one place, by letting the function tipc_msg_reverse() reallocate
the buffer and expand the header to 32 bytes when necessary. This
means that the socket code now can assume that the two previously
absent fields are present in the header when a message needs to be
rejected. This opens up for some further simplifications of the
socket code.

====================
Intel Wired LAN Driver Updates 2015-07-23

This series contains updates to e1000e, igb, ixgbevf, i40e and i40evf.

Emil extends the reporting of the RSS key and hash table by adding support
for x550 VFs.

Jia-Ju Bai fixes a QoS issue in e1000e where the error handling lacked a
call to pm_qos_remove_request() to cleanup the QoS request made in
e1000_open().

Todd updates igb to report unsupported for ethtool coalesce settings
that are not supported.  Also updated the driver to use the ARRAY_SIZE()
macro.

Carolyn fixes and refactors the dynamic ITR code for i40e and i40evf
which would never change dynamically.  So update the switch() statement
to have a default case and switch on "new_latency_range" versus the
current ITR setting.

Shannon cleans up i40e code, where there were un-needed goto's.  Also
clean up error status messages that were causing some confusion in
PHY and FCoE setup error reports.

Mitch updates the virtual channel interface to prepare for the x722 device
and other future devices, so that the VF driver can report what its
capable of supporting to the PF driver.  Updates the i40evf driver to
handle resets like Core or EMP resets, where the device is reinitialized
and the VF will not get the same VSI.

Jesse updates the i40e and i40evf driver to use the kernel BIT() and
BIT_ULL() macros.
