This patch removes the not-that-useful message in the
r6040_timer which prints the PHY status. Instead
replace it with a call to mii_check_media which will
update the link status and print it on startup.

The r8169 driver supports 3 different families of network chips
(RTL8169, RTL8168 and RTL8101). When an unknown version is found, the
driver currently always defaults to the RTL8169 variant. This has very
little chance to ever work for chips of the other families. So better
define a per-family default.

Inspired by the patch for 8139too (bda6a15a).
Currently we can't set mac address on a running ucc_geth device.
But this is needed when you use this device as a bonding slave in
bonding device in balance-alb mode. So add this feature for ucc_geth
device.

If we loaded the driver with out a SFP module plugged in it would
leave it in a state that make it later unable to link when a module
was plugged in. This patch corrects that by:
ixgbe_probe() - moving the check for IXGBE_ERR_SFP_NOT_PRESENT from
after get_invariants() to after reset_hw() as now reset_hw() is
where this condition will be indentified.
ixgbe_reset_hw_82598() - Enable this function to now return
IXGBE_ERR_SFP_NOT_PRESENT.
ixgbe_identify_sfp_module_generic() - This where the lack of SFP
module is detected. Modifications are added to allow a different
return value for modules that just haven't been plugged in yet.
Other functions were updated to allow correct logging.

Device ID 0x10d8 is the default silicon device ID for 82599. However, the
device will not be functional without an EEPROM, so we want to prevent the
driver from loading on the device. Otherwise, the driver will load, but no
PHY setup or PCIe setup will occur, causing the device to be unusable. To
prevent users from encountering this, just remove the device ID.

Based on previous patch from Jesper Dangaard Brouer.
The RNBC (Receive No Buffers Count) register for the 82576, indicate
that frames were received when there were no available buffers in host
memory to store those frames (receive descriptor head and tail
pointers were equal). The packet is still received by the NIC if
there is space in the FIFO on the NIC.
As the RNBC value is not a packet drop, the driver stores this value
in net_stats.rx_fifo_errors to indicate that there were no system
buffers available for the incoming packet. Actual dropped packets
are counted in the MPC value.
Saving the stats in dev->net_stats makes it visible via
/proc/net/dev as "fifo", and thus viewable to ifconfig
as "overruns" and 'netstat -i' as "RX-OVR".
The Receive No Buffers Count (RNBC) can already be queried by
ethtool -S as "rx_no_buffer_count".

Based on the previous patches from Jesper Dangaard Brouer <hawk@comx.dk>
Implement reading the per queue drop stats register
RQDPC (Receive Queue Drop Packet Count). It counts the number of
packets dropped by a queue due to lack of descriptors available.
Notice RQDPC (Receive Queue Drop Packet Count) stats only gets
incremented, if the DROP_EN bit it set (in the SRRCTL register
for that queue). If DROP_EN bit is NOT set, then the some what
equivalent count is stored in RNBC (not per queue basis).
The RQDPC register is only 12 bit, thus the precision might
suffer due to overrun in-netween the watchdog polling interval.

Since commit 0fd56bb5be6455d0d42241e65aed057244665e5e ("gianfar:
Add support for skb recycling"), gianfar puts skbuffs that are in
the rx ring back onto the recycle list as-is in case there was a
receive error, but this breaks the following invariant: that all
skbuffs on the recycle list have skb->data = skb->head + NET_SKB_PAD.
The RXBUF_ALIGNMENT realignment done in gfar_new_skb() will be done
twice on skbuffs recycled in this way, causing there not to be enough
room in the skb anymore to receive a full packet, eventually leading
to an skb_over_panic from gfar_clean_rx_ring() -> skb_put().
Resetting the skb->data pointer to skb->head + NET_SKB_PAD before
putting the skb back onto the recycle list restores the mentioned
invariant, and should fix this issue.

Calling cancel_delayed_work() from inside
spin_lock_irqsave, introduces a potential deadlock.
As explained by Johannes Berg <johannes@sipsolutions.net>
A - lock
T - timer
phase CPU 1 CPU 2
---------------------------------------------
some place that calls
cancel_timer_sync()
(which is the | code)
lock-irq(A)
| "lock-irq"(T)
| "unlock"(T)
| wait(T)
unlock(A)
timer softirq
"lock"(T)
run(T)
"unlock"(T)
irq handler
lock(A)
unlock(A)
Now all that again, interleaved, leading to deadlock:
lock-irq(A)
"lock"(T)
run(T)
IRQ during or maybe
before run(T) --> lock(A)
"lock-irq"(T)
wait(T)
We fix this by moving the call to cancel_delayed_work() into workqueue.
There are cases where the work may not actually be queued or running
at the time we are trying to cancel it, but cancel_delayed_work() is
able to deal with this.
Also cleanup iwl_set_mode related to this call. This function
(iwl_set_mode) is only called when bringing interface up and there will
thus not be any scanning done. No need to try to cancel scanning.
Fixes http://bugzilla.kernel.org/show_bug.cgi?id=13224, which was also
reported at http://marc.info/?l=linux-wireless&m=124081921903223&w=2 .

Commit e8f055f0c3b ("ath5k: Update reset code") subtly changed the
code that computes floating point values for the PHY3_TIMING register
such that the exponent is off by a decimal point, which can cause
problems with OFDM channel operation.
get_bitmask_order() actually returns the highest bit set plus one,
whereas the previous code wanted the highest bit set. Instead, use
ilog2 which is what this code is really calculating. Also check
coef_scaled to handle the (invalid) case where we need log2(0).

Periodic RX interrupt needed with ICT interrupt to prevent RX race.
Sending RX interrupt require many steps to be done in the
the device:
1- write interrupt to current index in ICT table.
2- dma RX frame.
3- update RX shared data to indicate last write index.
4- send interrupt.
This could lead to RX race, driver could receive RX interrupt
but the shared data changes does not reflect that.
this could lead to RX race, RX periodic will solve this race

Add new lock to be used when accessing some registers. Also move
the register lock and iwl_grab_nic_access inside the function for register access. This
will prevent from forgetting to hold locks and nic access in the right way and make code
easier to maintain.
We over use the priv->lock spin lock and I guess we need to add new
one for Tx queue after that we might need to change most of these lock to
BH and just keep priv->lock as irq type.
