netdev_open() will return without cleaning up net device or hardware state
if firmware loading fails. This results in a BUG() on a second attempt to
bring the interface up, reported in
<http://bugzilla.kernel.org/show_bug.cgi?id=15091>, and probably has even
worse effects if the driver is removed afterwards.
Call netdev_close() to clean up on failure.

Because DTIM information is required for powersave
but is only conveyed in beacons, wait for a beacon
before enabling powersave, and change the way the
information is conveyed to the driver accordingly.
mwl8k doesn't currently seem to implement PS but
requires the DTIM period in a different way; after
talking to Lennert we agreed to just have mwl8k do
the parsing itself in the finalize_join work.

The commit 0b5ccb2(title:ipv6: reassembly: use seperate reassembly queues for
conntrack and local delivery) has broken the saddr&&daddr member of
nf_ct_frag6_queue when creating new queue. And then hash value
generated by nf_hashfn() was not equal with that generated by fq_find().
So, a new received fragment can't be inserted to right queue.
The patch fixes the bug with adding member of user to nf_ct_frag6_queue structure.

I have seen RX stalls on a machine that experienced a suspected
OOM. After the stall, the RX buffer is empty on the guest side
and there are exactly 16 entries available on the host side. As
the number of entries is less than that required by a maximal
skb, the host cannot proceed.
The guest did not have a refill job scheduled.
My diagnosis is that an OOM had occured, with the delayed refill
job scheduled. The job was able to allocate at least one skb, but
not enough to overcome the minimum required by the host to proceed.
As the refill job would only reschedule itself if it failed completely
to allocate any skbs, this would lead to an RX stall.
The following patch removes this stall possibility by always
rescheduling the refill job until the ring is totally refilled.
Testing has shown that the RX stall no longer occurs whereas
previously it would occur within a day.

The low-level MCDI code always uses 32-bit MMIO operations, and
callers must pad input and output buffers to multiples of 4 bytes.
The MCDI NVRAM functions are not doing this. Also, their buffers are
declared as variable-length arrays with no explicit maximum length.
Switch to a fixed buffer size based on the chunk size used by the
MTD driver (which is a multiple of 4).

Due to a hardware bug in the SFC9000 family, the firmware must
transfer raw GMAC statistics to host memory before aggregating them
into the cooked (speed-independent) MAC statistics. Extend the stats
buffer to support this.
The length of the buffer is explicit in the MAC_STATS command, so this
change is backward-compatible on both sides.
