because xfrm policy direction has same value with corresponding
flow direction, so this problem is covered.
In xfrm_lookup and __xfrm_policy_check, flow_cache_lookup is used to
accelerate the lookup.
Flow direction is given to flow_cache_lookup by policy_to_flow_dir.
When the flow cache is mismatched, callback 'resolver' is called.
'resolver' requires xfrm direction,
so convert direction back to xfrm direction.

The rework of the kernel hlist implementation "hlist: drop the node parameter
from iterators" (b67bfe0d42cac56c512dd5da4b1b347a23f4b70a) created some
fallout in the form of non matching comments and obsolete code.
Additionally to the cleanup this patch adds a WARN() statement to catch the
caller of the wrong filter removal request.

TCPCT uses option-number 253, reserved for experimental use and should
not be used in production environments.
Further, TCPCT does not fully implement RFC 6013.
As a nice side-effect, removing TCPCT increases TCP's performance for
very short flows:

Conflicts:
net/openvswitch/vport-internal_dev.c
Jesse Gross says:
====================
A couple of minor enhancements for net-next/3.10. The largest is an
extension to allow variable length metadata to be passed to userspace
with packets.
There is a merge conflict in net/openvswitch/vport-internal_dev.c:
A existing commit modifies internal_dev_mac_addr() and a new commit
deletes it. The new one is correct, so you can just remove that function.

This patch generalizes VXLAN forwarding table entries allowing an administrator
to:
1) specify multiple destinations for a given MAC
2) specify alternate vni's in the VXLAN header
3) specify alternate destination UDP ports
4) use multicast MAC addresses as fdb lookup keys
5) specify multicast destinations
6) specify the outgoing interface for forwarded packets
The combination allows configuration of more complex topologies using VXLAN
encapsulation.

[ As explained by Linus Walleij: "U5500 used this, but was cancelled
and the silicon did not reach anyone outside ST-Ericsson. Then for
the next platforms, we have gone for the leaner & cleaner approach
of using virtio, rpmesg and rproc." ]

I believe these error messages are already logged
on allocation failure by warn_alloc_failed and so
get a dump_stack on OOM.
Remove the unnecessary additional error logging.
Around these deletions:
o Alignment neatening.
o Remove unnecessary casts of dma_alloc_coherent.
o Hoist assigns from ifs.

This patch allows LRO aggregation on bonded devices that contain an
NX3031 device. It also adds a for_each_netdev_in_bond_rcu(bond, slave)
macro which executes for each slave that has bond as master.
V3: After testing and discussing this with Rajesh, I decided to keep the
vlan ip cache and just rename it to ip_cache since it will store bond
ip addresses too. A new master flag has been added to the ip cache to
denote that the address has been added because of a master device.
I've taken care of the enslave/release cases by checking for various
combinations of events and flags (e.g. netxen has a master, it's a
bond master and it's not marked as a slave means it is being enslaved
and is dev_open()ed in bond_enslave).
I've changed netxen_free_ip_list() to have a "master" parameter which
causes all IP addresses marked as master to be deleted (used when a
netxen is being released). I've made the patch use the new upper
device API as well. The following cases were tested:
- bond -> netxen
- vlan -> netxen
- vlan -> bond -> netxen
V2: Remove local ip caching, retrieve addresses dynamically and
restore them if necessary.
Note: Tested with NX3031 adapter.

- sets up and checks flags correctly when coming up as master and finding

T5 adapter does not support onchip queue memory. Present logic fails to
allocate QP for T5 and returns an error. Also, if module parameter ocqp_support
is zero then we are unable to allocate QP which should not be the case. Ideally
if ocqp_support parameter is 0 or onchip queue support is disable then host QP
should be allocated before returning an error.

It enables direct DMA by HW to memory region PBL arrays and fast register PBL
arrays from host memory, vs the T4 way of passing these arrays in the WR itself.
The result is lower latency for memory registration, and larger PBL array
support for fast register operations.
This patch also updates ULP_TX_MEM_WRITE command fields for T5. Ordering bit of
ULP_TX_MEM_WRITE is at bit position 22 in T5 and at 23 in T4.
