On certain platforms, BE hardware could falsely indicate UE.
For BE family of NICs, do not set hw_error based on the UE bits.
If there was a real fatal error, the corresponding h/w block will
automatically go offline and stop traffic.

Pull networking changes from David Miller:
1) GRE now works over ipv6, from Dmitry Kozlov.
2) Make SCTP more network namespace aware, from Eric Biederman.
3) TEAM driver now works with non-ethernet devices, from Jiri Pirko.
4) Make openvswitch network namespace aware, from Pravin B Shelar.
5) IPV6 NAT implementation, from Patrick McHardy.
6) Server side support for TCP Fast Open, from Jerry Chu and others.
7) Packet BPF filter supports MOD and XOR, from Eric Dumazet and Daniel
Borkmann.
8) Increate the loopback default MTU to 64K, from Eric Dumazet.
9) Use a per-task rather than per-socket page fragment allocator for
outgoing networking traffic. This benefits processes that have very
many mostly idle sockets, which is quite common.
From Eric Dumazet.
10) Use up to 32K for page fragment allocations, with fallbacks to
smaller sizes when higher order page allocations fail. Benefits are
a) less segments for driver to process b) less calls to page
allocator c) less waste of space.
From Eric Dumazet.
11) Allow GRO to be used on GRE tunnels, from Eric Dumazet.
12) VXLAN device driver, one way to handle VLAN issues such as the
limitation of 4096 VLAN IDs yet still have some level of isolation.
From Stephen Hemminger.
13) As usual there is a large boatload of driver changes, with the scale
perhaps tilted towards the wireless side this time around.
Fix up various fairly trivial conflicts, mostly caused by the user
namespace changes.

Current VFs enumeration algorithm used in be_find_vfs does not take domain
number into the match. The match found in igb/ixgbe is more elegant and

1) link_status_query() is always called to query the link-speed (speed
after applying qos). When there is no qos setting, link-speed is derived from
port-speed. Do all this inside this routine and hide this from the callers.
2) adpater->phy.forced_port_speed is not being set anywhere after being
initialized. Get rid of this variable.
3) Ignore async link_speed notifications till the initial value has been
fetched from FW.

Changes from commit df505e were incorrectly over-written by commit 10ef9ab.
Fixing the same.
Change log of the original fix:
Currently RSS rings are not created in a multi-channel config.
RSS rings can be created on one (out of four) interfaces per port in a
multi-channel config. Doing this insulates the driver from a FW bug wherin
multi-channel config is wrongly reported even when not enabled. This also
helps performance in a multi-channel config, as one interface per port gets
RSS rings.

In the patch "netpoll: re-enable irq in poll_napi()", I tried to

by reenabling IRQ before calling ->poll, but it seems more
problems are introduced after that patch:
http://ozlabs.org/~akpm/stuff/IMG_20120824_122054.jpg
http://marc.info/?l=linux-netdev&m=134563282530588&w=2
So it is safe to fix be2net driver code directly.
This patch reverts the offending commit and fixes be_poll() by
avoid disabling BH there, this is okay because be_poll()
can be called either by poll_napi() which already disables
IRQ, or by net_rx_action() which already disables BH.

skb_fill_rx_data() pulls 64 byte of data in skb->data
Its too much for TCP (with no options) on IPv4, as total size of headers
is 14 + 40 = 54
This means tcp stack and splice() are suboptimal, since tcp payload
is in part in tcp->data, and in part in skb frag.
