from the public address in creating a private address, if we have not
received a router advertisement in a while, tstamp + temp_valid_lft might be
< now. If this happens, the new address is created inside
ipv6_create_tempaddr, then the loop within addrconf_verify starts again and
the address is immediately deleted. We are left with no temporary addresses
on the interface, and no more will be created until the public IP address is

left on the public address or the config option PLUS the current age of the

macb: Don't re-enable interrupts while in polling mode
On a busy network, the macb driver could get stuck in the interrupt
handler, quickly triggering the watchdog, due to a confluence of
factors:
1. macb_poll re-enables interrupts unconditionally, even when it will
be called again because it exhausted its rx budget
2. macb_interrupt only disables interrupts after scheduling
macb_poll, but scheduling fails when macb_poll is already scheduled
because it didn't call napi_complete
3. macb_interrupt loops until the interrupt status register is clear,
which will never happen in this case if the driver doesn't disable
the RX interrupt
Since macb_interrupt runs in interrupt context, this effectively locks
up the machine, triggering the hardware watchdog.
This issue was readily reproducible on a flooded network with a
modified 2.6.27.48 kernel. The same problem appears to still be in the
2.6.36-rc8 driver code, so I am submitting this patch against that
version. I have not tested this version of the patch except to make

from our systems engineering team.
The description of changes in this update:
Improves ability to support very strong Rx conditions.
Enhances DFS support for AP-mode.
Improves performance of Tx carrier leak calibration.
Adds support for Japan channel 14 Tx filtering requirements.
Improves Tx power accuracy.
Impact:
Update required to address degraded throughput at very short range.
Update required for AP-mode DFS certification.
Update required to comply to IEEE Tx carrier leak specification.
May not meet expected +/- 2 dB Tx power accuracy without update.
The most important fix here would be the TX carrier leakage required

The priv is part of the memory allocated by alloc_candev().
This patch moved the free it after last usage of priv.
While there convert all free_netdev() to free_candev() (which is currently
just a wrapper around free_netdev()) to be symetrically with the allocation
via alloc_candev().

The AT91_MID_MIDE bit must be set in order to receive extended frames.
The reception of an extended frame sets this bit, while reception of
standard frames resets it. This results in some lost extended frames in
an extended ID only environment. But leads to unpredictable lost
extended ID frames in a mixed environment.
The problem is fixed by setting the AT91_MID_MIDE after reception of a
CAN frame.

can: Topcliff: Add PCH_CAN driver.
CAN driver of Topcliff PCH
Topcliff PCH is the platform controller hub that is going to be used in
Intel's upcoming general embedded platform. All IO peripherals in
Topcliff PCH are actually devices sitting on AMBA bus.
Topcliff PCH has CAN I/F. This driver enables CAN function.

connector: remove lazy workqueue creation
Commit 1a5645bc (connector: create connector workqueue only while
needed once) implements lazy workqueue creation for connector
workqueue. With cmwq now in place, lazy workqueue creation doesn't
make much sense while adding a lot of complexity. Remove it and
allocate an ordered workqueue during initialization.
This also removes a call to flush_scheduled_work() which is deprecated
and scheduled to be removed.
