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.

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.

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.

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.
