Use GCC's -MD feature to generate a dependency file for each feature test .c file,
and include that .d file in the config/feature-checks/Makefile.
This allows us to do two things:
- speed up feature tests
- detect removal or changes in build dependencies - including system libraries/headers

Start the split-out of the feature check code by adding a list of features to be
tested, and rules to process that list by building its matching feature-check
file in config/feature-checks/test-<feature>.c.
Add 'hello' as the initial feature.
This structure will allow us to build split-out feature checks in parallel and
thus speed up feature detection dramatically.
No change in functionality: no feature check is used by the build rules yet.

Some more fixes for EF10 support; hopefully the last lot:
1. Fixes for reading statistics, from Edward Cree and Jon Cooper.
2. Addition of ethtool statistics for packets dropped by the hardware
before they were associated with a specific function, from Edward Cree.
3. Only bind to functions that are in control of their associated port,
as the driver currently assumes this is the case.

Steinar reported FQ pacing was not working for UDP flows.
It looks like the initial sk->sk_pacing_rate value of 0 was
a wrong choice. We should init it to ~0U (unlimited)
Then, TCA_FQ_FLOW_DEFAULT_RATE should be removed because it makes
no real sense. The default rate is really unlimited, and we
need to avoid a zero divide.

Unlike ipv4, the struct member hlen holds the length of the GRE and ipv6
headers. This length is also counted in dev->hard_header_len.
Perhaps, it's more clean to modify the hlen to count only the GRE header
without ipv6 header as the variable name suggest, but the simple way to fix
this without regression risk is simply modify the calculation of the limit
in ip6gre_tunnel_change_mtu function.
Verified in kernel version v3.11.

If a guest is destroyed without transitioning its frontend to CLOSED,
the domain becomes a zombie as netback was not grant unmapping the
shared rings.
When removing a VIF, transition the backend to CLOSED so the VIF is
disconnected if necessary (which will unmap the shared rings etc).
This fixes a regression introduced by
279f438e36 (xen-netback: Don't destroy
the netdev until the vif is shut down).

net/mlx4_en: Fix pages never dma unmapped on rx
This patchset fixes a bug introduced by commit 51151a16 (mlx4: allow order-0
memory allocations in RX path). Where dma_unmap_page wasn't called.
Changes from V0:
- Added "Rename name of mlx4_en_rx_alloc members". Old names were confusing.
- Last frag in page calculation was wrong. Since all frags in page are of the
same size, need to add this frag_stride to end of frag offset, and not the
size of next frag in skb.

This patch fixes a bug introduced by commit 51151a16 (mlx4: allow
order-0 memory allocations in RX path).
dma_unmap_page never reached because condition to detect last fragment
in page is wrong. offset+frag_stride can't be greater than size, need to
make sure no additional frag will fit in page => compare offset +
frag_stride + next_frag_size instead.
next_frag_size is the same as the current one, since page is shared only
with frags of the same size.

This patch will fix RX packets errors when receiving big size
of data by set bit RNC = 1.
RNC - Receive Enable Control
0: Upon completion of reception of one frame, the E-DMAC writes
the receive status to the descriptor and clears the RR bit in
EDRRR to 0.
1: Upon completion of reception of one frame, the E-DMAC writes
(writes back) the receive status to the descriptor. In addition,
the E-DMAC reads the next descriptor and prepares for reception
of the next frame.
In addition, for get more stable when receiving packets, I set
maximum size for the transmit/receive FIFO and inserts padding
in receive data.

Fix race conditions in mrf24j40 interrupts
After testing with the betas of this patchset, it's been rebased and is
ready for inclusion.
David Hauweele noticed that the mrf24j40 would hang arbitrarily after some
period of heavy traffic. Two race conditions were discovered, and the
driver was changed to use threaded interrupts, since the enable/disable of
interrupts in the driver has recently been a lighning rod whenever issues
arise related to interrupts (costing engineering time), and since threaded
interrupts are the right way to do it.
====================
Signed-off-by: David S. Miller <davem@davemloft.net>
The mrf24j40 generates level interrupts. There are rare cases where it
appears that the interrupt line never gets de-asserted between interrupts,
causing interrupts to be lost, and causing a hung device from the driver's
perspective. Switching the driver to interpret these interrupts as
level-triggered fixes this issue.
