When changing DCB parameters, ixgbe needs to have the MAC reset. The way
the flow control code is setup today, PFC will be disabled on a reset.
This patch adds a new flow control type for PFC, and then has the netlink
layer take care of toggling which type of flow control to enable.

As noticed by Alan Cox, it is possible for e1000e to exit its interrupt
handler or NAPI with interrupts enabled even when the driver is unloading or
being configured administratively down.

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.
reference with test program:
http://kerneltrap.org/mailarchive/linux-netdev/2009/3/14/5160514/thread
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
reprogramming.

this is in regards to
http://bugzilla.kernel.org/show_bug.cgi?id=12876
where it appears that e1000 can leave its interrupt enabled after
exiting the driver. Fix the bug by making the interrupt enable
paths more aware of the driver exiting.
Thanks to Alan Cox for the poke and initial investigation.

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
Up Delay (ms): 0
Down Delay (ms): 0
Slave Interface: eth1
MII Status: up
Link Failure Count: 0
Permanent HW addr: 00:1f:1f:01:2f:22
----
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:
----
ADDRCONF(NETDEV_UP): bond0: link is not ready
event_dev: bond0, event: 1

<<<<cable plug>>>>

IFF_SLAVE
event_dev: eth1, event: 8
IFF_SLAVE
bonding: bond0: first active interface up!
event_dev: bond0, event: 4
IFF_MASTER
----
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.
