The ibm_newemac driver includes code which assumes that the
work_struct which is included in every delayed_work is the first
member of that structure. This is currently the case but might change
in the future, so use to_delayed_work() instead, which doesn't make
such an assumption.

e1000 (and e1000e, 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.

It seems that trivial reset of pcount to one was not sufficient
in tcp_retransmit_skb. Multiple counters experience a positive
miscount when skb's pcount gets lowered without the necessary
adjustments (depending on skb's sacked bits which exactly), at
worst a packets_out miscount can crash at RTO if the write queue
is empty!
Triggering this requires mss change, so bidir tcp or mtu probe or

Original comment (Karsten):
On a MSI MS-6702E mainboard, when in rtl8169_init_one() for the first time
after BIOS has run, IntrStatus reads 5 after chip has been reset.
IntrStatus should equal 0 there, so patch changes IntrStatus reset to happen
after chip reset instead of before.
Remark (Francois):
Assuming that the loglevel of the driver is increased above NETIF_MSG_INTR,
the bug reveals itself with a typical "interrupt 0025 in poll" message
at startup. In retrospect, the message should had been read as an hint of
an unexpected hardware state several months ago :o(

Impact: Fix
Yinghai Lu found one system with 82575EB where, in the kernel that is
kexeced, probe igb failed with -2, the reason being that the adapter
could not be brought back from D3 by the kexec kernel, most probably
due to quirky hardware (it looks like the same behavior happened on
forcedeth).
Prevent igb from putting the adapter into D3 during shutdown except
when we going to power off the system. For this purpose, seperate
igb_shutdown() from igb_suspend() and use the appropriate PCI PM
callbacks in both of them.
