This patch resolves issues seen when running netconsole and rebooting via
reboot -f.  The issue was due to the fact that we were attempting to
perform interrupt actions when the q_vectors and rings had already been
freed via the ixgbe_shutdown routines.

During TX timeout procedure dev could be awoken too early, e.g. by
sky2_complete_tx() called from sky2_down(). Then sky2_xmit_frame()
can run while buffers are freed causing an oops. This patch fixes it
by adding netif_device_present() test in sky2_tx_complete().

When ieee80211_monitor_select_queue encounters data frames, it selects
the WMM AC based on skb->priority and assumes that skb->priority
contains a valid 802.1d tag. However this assumption is incorrect, since
ieee80211_select_queue has not been called at this point.
If skb->priority > 7, an array overrun occurs, which could lead to
invalid values, resulting in crashes in the tx path.
Fix this by setting skb->priority based on the 802.11 header for QoS
frames and using the default AC for all non-QoS frames.

3c509 was changed to support ethtool in 2002, making the 'xcvr' module

to the modern driver model and this parameter was removed.  Fix the
documentation to refer to ethtool rather than the module parameter.

Smatch (and presumably other static checkers) complain that MAX_TID_COUNT is
past the end of the array.  In the resulting discussion, Zhu Yi pointed out
that this value is not used in real life and the assignment was only there to
silence a gcc warning.

If there were a bug in the surrounding code and the value were used, the
WARN_ON(!qc) would print a warning before the crash.

On beacon change update notification from mac we are not disabling
the tx in adhoc mode. Mac sends BSS_CHANGED_BEACON_ENABLED when
station leaves IBSS. Driver should indicate uCode to not to send
anything on receiving this notification.

Functionality to indicate uCode is duplicated across
two notifications so created a common function called iwl_set_no_assoc.

When txq read_ptr equals to write_ptr, iwl_queue_used should
always return false. Because there is no used TFD in this case.

This is a complementary fix to the fix already included in commit "iwl3945:
fix panic in iwl3945 driver". Both fixes are needed to address the panic
below.

some SPARC systems (supported by the tulip driver) and also in PCI
expansion cards (supported by the dmfe driver).  There is no
difference in the PCI device ids for the two different configurations,
so these drivers both claim the device ids.  However, it is possible
to distinguish the two configurations by the presence of Open Firmware

As noticed by Dan Carpenter <error27@gmail.com>, update_nl_seq()
currently contains an out of bounds read of the seq_aft_nl array
when looking for the oldest sequence number position.

Fix it to only compare valid positions.

If NET_SKB_PAD is not a multiple of the cache line size, mv643xx_eth
allocates a couple of extra bytes at the start of each receive buffer
to make the data payload end up on a cache line boundary.

These extra bytes are skb_reserve()'d before DMA mapping, so they
should not be included in the DMA map byte count (as the mapping is
done starting at skb->data), nor should they be included in the
receive descriptor buffer size field, or the hardware can end up
DMAing beyond the end of the buffer, which can happen if someone
sends us a larger-than-MTU sized packet.

This problem was introduced in commit 7fd96ce4 ("mv643xx_eth:
rework receive skb cache alignment", May 6 2009), but hasn't appeared
to be problematic so far, probably as the main users of mv643xx_eth
all have NET_SKB_PAD == L1_CACHE_BYTES.

A failure on request_irq() is always fatal but unlike other fatal
errors it's only reported to the user if net_debug is set. Make the
diagnostic unconditional and raise the priority so that errors are
more obvious to the user.

Don't send flow control settings to any port other than the modem port.
Older firmware ignored this request but did sent a reply. Newer firmware just
ignores it without reply and causes a 5 second timeout every time a port
(except for the modem port) is opened or if tiocm settings are changed.

Don't change the state of a port if it's not open. This fixes an issue where a
port sometimes has to be opened twice before data can be received.
