It looks like mac80211 can request the driver to start beaconing with
a beacon interval of zero in some cases (at least for mesh point). This
does not sound correct and something may need to be fixed in
mac80211. However, taken into account the unpleasantness of getting
stuck in an infinite busy loop with rtnl_lock held, let's add a quick
workaround in the driver to avoid the worst symptom while someone more
familiar with the mesh implementation can figure out what should be done
with mac80211 as far as beacon interval configuration is concerned.

I have a TrendNet 652-BRP running OpenWRT + ath9k very well. The only
problem is that the beacon gets stuck maybe once a day. After
Vasanthakumar Thiagarajan's "ath9k: cleanup beacon parameters
configuration" patch, ath9k would nearly re-configure the beacons after it
detected the stuck beacon, and did a reset. But it would fail the
SC_OP_TSF_RESET check in ath_beacon_config_ap. This patch gets the beacon
fully reconfigured after the reset.

Patch to fix bad length checking in e1000. E1000 by default does two
things:
1) Spans rx descriptors for packets that don't fit into 1 skb on recieve
2) Strips the crc from a frame by subtracting 4 bytes from the length prior to
doing an skb_put
Since the e1000 driver isn't written to support receiving packets that span
multiple rx buffers, it checks the End of Packet bit of every frame, and
discards it if its not set. This places us in a situation where, if we have a
spanning packet, the first part is discarded, but the second part is not (since
it is the end of packet, and it passes the EOP bit test). If the second part of
the frame is small (4 bytes or less), we subtract 4 from it to remove its crc,
underflow the length, and wind up in skb_over_panic, when we try to skb_put a
huge number of bytes into the skb. This amounts to a remote DOS attack through
careful selection of frame size in relation to interface MTU. The fix for this
is already in the e1000e driver, as well as the e1000 sourceforge driver, but no
one ever pushed it to e1000. This is lifted straight from e1000e, and prevents
small frames from causing the underflow described above

The phy power state persists across reboots; Windows, some BIOSes, and
older versions of Linux don't bother to power up the phy again, forcing
users to remove all power to get the interface working (see

Do not call t3_link_fault() under spinlock, as it calls msleep().
Besides, only the access to pi->link_fault needs to be serialized.
Also initialize local variables before checking the link status,
link state fields might otherwise end up containing garbage.

Commit 5e68b772e6
cxgb3: map entire Rx page, feed map+offset to Rx ring.
introduced a regression on platforms defining DECLARE_PCI_UNMAP_ADDR()
and related macros as no-ops.
Rx descriptors are fed with the a page buffer bus address + page chunk offset.
The page buffer bus address is set and retrieved through
pci_unamp_addr_set(), pci_unmap_addr().
These functions being meaningless on x86 (if CONFIG_DMA_API_DEBUG is not set).
The HW ends up with a bogus bus address.
This patch saves the page buffer bus address for all plaftorms.

This patch makes the korina driver poll the media
for link change. This is actually required on
Mikrotik RB532 (not RB532A) for korina to

This replaces dma_sync_single() with dma_sync_single_for_cpu() because
dma_sync_single() is an obsolete API; include/linux/dma-mapping.h says:
/* Backwards compat, remove in 2.7.x */
#define dma_sync_single dma_sync_single_for_cpu
#define dma_sync_sg dma_sync_sg_for_cpu

Second round of drivers for Gb cards (and NIU one I forgot in the 10GB round)
Now that core network takes care of trans_start updates, dont do it
in drivers themselves, if possible. Drivers can avoid one cache miss
(on dev->trans_start) in their start_xmit() handler.
Exceptions are NETIF_F_LLTX drivers

When the i2400m is connected to a network, the host interface (USB)
cannot be suspended. For that to happen, the device has to have
negotiated with the basestation to put the link on IDLE state.
If the host tries to put the device in standby while it is connected
but not idle, the device resets, as the driver should not do that.
To avoid triggering that, when the USB susbsytem requires the driver
to autosuspend the device, the driver checks if the device is not yet
idle. If it is not, the request is requested (will be retried again
later on after the autosuspend timeout). At some point the device will
enter idle and the request will succeed (unless of course, there is
network traffic, but at that point, there is no idle neither in the
link or the host interface).

From a fix by Cindy H Kao:
Block size has to be set before sending IOE enable because the
firmware reads the block size register before it reads IOE register.

Functions i2400m_report_tlv*() are only called from
i2400m_report_hook(), called in a workqueue by
i2400m_report_hook_work(). The scheduler checks for device readiness
before scheduling.
Added an extra check for readiness in i2400m_report_hook_work(), which
makes all the checks down the line redundant.
Obviously the device state could change in the middle, but error
handling would take care of that.

By running 'echo 1 > /sys/kernel/debug/wimax:wmxX/i2400m/trace_msg_from_user',
the driver will echo to user space all the commands being sent to the
device from user space, along with the responses.
However, this only helps with the commands being sent from user space;
with this patch, the trace hook is moved to i2400m_msg_to_dev(), which
is the single access point for running commands to the device (both by
user space and the kernel driver). This allows better debugging by
having a complete stream of commands/acks and reports.

When commands are sent from user space, trace both the command sent
and the answer received over the "echo" pipe instead of over the
"trace" pipe when command tracing is enabled. As well, when the device
sends a reports/indications, send it over the "echo" pipe.
The "trace" pipe is used by the device to send firmware traces;
gets confusing. Another named pipe makes it easier to split debug
information.

The WiMAX i2400m driver needs to generate a fake source MAC address to
fake an ethernet header (for destination, the card's MAC is
used). This is the source of the packet, which is the basestation it
came from. The basestation's mac address is not usable for this, as it
uses its own namespace and it is not always available.
Currently the fake source MAC address was being set to all zeros,
which was causing trouble with bridging.
Use random_ether_addr() to generate a proper one that creates no
trouble.

First of all, it exposes the SKB list implementation.
Second of all it's not needed. If we get called here, we
successfully enqueued the URB with the linked SKB and
such a completion only gets called one time on such an
