This masks the PHY TX error interrupt, if debugging is disabled.
Currently we have a bug somewhere which triggers this interrupt once
in a while. (Depends on the network noise/quality). While this is nonfatal,
it scares the hell out of users and we frequently receive bugreports
that incorrectly identify this error message as the reason.
There's another problem with this. The PHY TX error interrupt is protected
with a watchdog that will restart the device if it keeps triggering very often.
This is used to fix interrupt storms from completely broken devices.
However, this watchdog might trigger in completely normal operation.
If the TX capacity of the card is saturated, the likeliness of the watchdog
triggering increases, as more TX errors occur. The current threshold
for the watchdog is 1000 errors in 15 seconds.
This patch adds a workaround for the issue by just enabling the interrupt
if debugging is disabled (by Kconfig or by modparam).
This has the downside that real fatal PHY TX errors are not caught anymore.
But this is nonfatal due to the following reasons:
* If the card is not able to transmit anymore, MLME will notice anyway.
* I did _never_ see a real fatal PHY TX error in a mainline b43 driver.
* It does _not_ result in interrupt storms or something like that.
It will simply result in a stalled card. It can be debugged by enabling
the debugging module parameter.

[...]
This is because the ucc_geth_stop() routine assumes that ugeth->phydev
is always initialized by the ucc_geth_open(), while it is not in case
of errors.
If we add a check to the ucc_geth_stop(), then another oops pops up:
Unable to handle kernel paging request for data at address 0x00000004
Faulting instruction address: 0xc01b46a4

That one happens because ucc_geth_stop() does not call phy_disconnect()
and so phylib state machine is running without any idea that a MAC has
just died.
Also, when device tree specifies fixed-link, and CONFIG_FIXED_PHY
is disabled, we'll get this oops:
0:01 not found

eth2: Cannot initialize PHY, aborting.

And again, ucc_geth_stop() assumes that ugeth->phydev is there, while
it isn't.
This patch fixes all three oopses simply by rearranging some code:
- In ucc_geth_open(): move init_phy() call to the beginning, so
that we only call ucc_geth_stop() with a PHY attached;
- Move phy_disconnect() call from ucc_geth_close() to
ucc_geth_stop(), so that we'll always disconnect the PHY.

e1000e (and e1000, igb, ixgbe, ixgb) all do a series of operations each
time a multicast address is added. The flow goes something like
1) stack adds one multicast address
2) stack passes whole current list of unicast and multicast addresses to
driver
3) driver clears entire list in hardware
4) driver programs each multicast address using iomem in a loop
This was causing multicast packets to be lost during the reprogramming
process.

Thanks to Dave Boutcher for his report and test program.
This driver fix prepares an array all at once in memory and programs it in
one shot to the hardware, not requiring an "erase" cycle. It would still
be possible for packets to be dropped while the receiver is off during

The tx cleanup routine was stopping after 64 packets and this was causing
issues resulting in the ring not being completely cleaned.
This change updates the driver to clean the entire ring and if it doesn't
it then will retry on the next pass.

I've hit an issue on my system when I've been using RealTek RTL8139D cards in
bonding interface in mode balancing-alb. When I enslave a card, the current
active slave (bond->curr_active_slave) is not set and the link is therefore
not functional.
----
# cat /proc/net/bonding/bond0
Ethernet Channel Bonding Driver: v3.5.0 (November 4, 2008)
Bonding Mode: adaptive load balancing
Primary Slave: None
Currently Active Slave: None
MII Status: up
MII Polling Interval (ms): 100

----
The thing that gets it right is when I unplug the cable and then I put it back
into the NIC. Then the current active slave is set to eth1 and link is working
just fine. Here is dmesg log with bonding DEBUG messages turned on:
----

----
The current active slave is set by calling bond_select_active_slave() function
from bond_miimon_commit() function when the slave (eth1) link goes to state up.
I also tested this on other machine with Broadcom NetXtreme II BCM5708
1000Base-T NIC and there all works fine. The thing is that this adapter is down
and goes up after few seconds after it is enslaved.
This patch calls bond_select_active_slave() in bond_enslave() function for modes
alb and tlb and makes sure that the current active slave is set up properly even
when the slave state is already up. Tested on both systems, works fine.
Notice: The same problem can maybe also occrur in mode 8023AD but I'm unable to
test that.

This patch fixes the bug reported in
http://bugzilla.kernel.org/show_bug.cgi?id=11681.
"Lots of device drivers register a 'struct device_driver' with
the '.bus' member set to '&platform_bus_type'. This is wrong,
since the platform_bus functions expect the 'struct device_driver'
to be wrapped up in a 'struct platform_driver' which provides
some additional callbacks (like suspend_late, resume_early).
The effect may be that platform_suspend_late() uses bogus data
outside the device_driver struct as a pointer pointer to the
device driver's suspend_late() function or other hard to
reproduce failures."(Lothar Wassmann)

This patch fixes the issue by removing offending (and somewhat
duplicate) code from init_phy() routine, and changes _probe()
function to use uec_mdio_bus_name().
Also, since we fully construct phy_bus_id in the _probe() routine,
we no longer need ->phy_address and ->mdio_bus fields in
ucc_geth_info structure.
I wish the patch would be a bit shorter, but it seems like the only
way to fix the issue in a sane way. Luckily, the patch has been
tested with real PHYs and fixed-link, so no further regressions
expected.

This fixes a locking bug in the dm9000 driver. It calls
request_irq() without setting IRQF_DISABLED ... which is
correct for handlers that support IRQ sharing, since that
behavior is not guaranteed for shared IRQs. However, its
IRQ handler then wrongly assumes that IRQs are blocked.
So the fix just uses the right spinlock primitives in the
IRQ handler.
NOTE: this is a classic example of the type of bug which
lockdep currently masks by forcibly setting IRQF_DISABLED
on IRQ handlers that did not request that flag.
