Jiri Pirko ccffad25b5 net: convert unicast addr list
This patch converts unicast address list to standard list_head using
previously introduced struct netdev_hw_addr. It also relaxes the
locking. Original spinlock (still used for multicast addresses) is not
needed and is no longer used for a protection of this list. All
reading and writing takes place under rtnl (with no changes).

I also removed a possibility to specify the length of the address
while adding or deleting unicast address. It's always dev->addr_len.

The convertion touched especially e1000 and ixgbe codes when the
change is not so trivial.

Sonic Zhang 805a8ab3ce netdev: bfin_mac: fix malformed UDP packet transmission when polling with KGDB
Writes to the DMA descriptors may sit in the internal Blackfin data buffers
and not actually be available when the DMA engine goes to fetch them.  This
does not typically happen, but when dealing with short/fast packets such as
UDP and polling KGDB, this occurs much more frequently.  Same goes for
heavy loads as seen by netperf tests or large scp transfers.  So force the
buffers to drain with SSYNC otherwise we get random malformed packets.

Ilpo Järvinen 2df9001edc tcp: fix loop in ofo handling code and reduce its complexity
Somewhat luckily, I was looking into these parts with very fine
comb because I've made somewhat similar changes on the same
area (conflicts that arose weren't that lucky though). The loop
was very much overengineered recently in commit 915219441d
(tcp: Use SKB queue and list helpers instead of doing it
by-hand), while it basically just wants to know if there are
skbs after 'skb'.

Also it got broken because skb1 = skb->next got translated into
skb1 = skb1->next (though abstracted) improperly. Note that
'skb1' is pointing to previous sk_buff than skb or NULL if at
head. Two things went wrong:
- We'll kfree 'skb' on the first iteration instead of the
  skbuff following 'skb' (it would require required SACK reneging
  to recover I think).
- The list head case where 'skb1' is NULL is checked too early
  and the loop won't execute whereas it previously did.

Conclusion, mostly revert the recent changes which makes the
cset very messy looking but using proper accessor in the
previous-like version.

The effective changes against the original can be viewed with:

Jiri Pirko 5d4e039b2c bonding: allow bond in mode balance-alb to work properly in bridge -try4.3
[PATCH net-next] bonding: allow bond in mode balance-alb to work properly in bridge -try4.3

(updated)
changes v4.2 -> v4.3
- memcpy the address always, not just in case it differs from master->dev_addr
- compare_ether_addr_64bits() is not used so there is no direct need to make new
  header file (I think it would be good to have bond stuff in separate file
  anyway).

changes v4.1 -> v4.2
- use skb->pkt_type == PACKET_HOST compare rather then comparing skb dest addr
  against skb->dev->dev_addr

The problem is described in following bugzilla:
https://bugzilla.redhat.com/show_bug.cgi?id=487763

Basically here's what's going on. In every mode, bonding interface uses the same
mac address for all enslaved devices (except fail_over_mac). Only balance-alb
will simultaneously use multiple MAC addresses across different slaves. When you
put this kind of bond device into a bridge it will only add one of mac adresses
into a hash list of mac addresses, say X. This mac address is marked as local.
But this bonding interface also has mac address Y. Now then packet arrives with
destination address Y, this address is not marked as local and the packed looks
like it needs to be forwarded. This packet is then lost which is wrong.

Notice that interfaces can be added and removed from bond while it is in bridge.

***
When the multiple addresses for bridge port approach failed to solve this issue
due to STP I started to think other way to solve this. I returned to previous
solution but tweaked one.

This patch solves the situation in the bonding without touching bridge code.
For every incoming frame to bonding the destination address is compared to
current address of the slave device from which tha packet came. If these two
match destination address is replaced by mac address of the master. This address
is known by bridge so it is delivered properly. Note that the comparsion is not
made directly, it's used skb->pkt_type == PACKET_HOST instead. This is "set"
previously in eth_type_trans().

I experimentally tried that this works as good as searching through the slave
list (v4 of this patch).

Inaky Perez-Gonzalez 2618ab774e wimax/i2400m: usb: fix device reset on autosuspend while not yet idle
When the i2400m is connected to a network, the host interface (USB)
cannot be suspended. For that to happen, the device has to have
negotiated with the basestation to put the link on IDLE state.

If the host tries to put the device in standby while it is connected
but not idle, the device resets, as the driver should not do that.

To avoid triggering that, when the USB susbsytem requires the driver
to autosuspend the device, the driver checks if the device is not yet
idle. If it is not, the request is requested (will be retried again
later on after the autosuspend timeout). At some point the device will
enter idle and the request will succeed (unless of course, there is
network traffic, but at that point, there is no idle neither in the
link or the host interface).
