As the NIC PCI function may be used by other protocols, the chip interrupts
must be enabled in be_probe() itself rather than be_open().

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.

This patch defines the common operations to support multiple chips. It
includes common header file modifications to support the current chips
(T4 and T5). It also includes the following bug fixes:
- reconfirms the rnode state after an implicit logo.
- corrects the stats array size.
- sets up and checks flags correctly when coming up as master and finding
the card initialized

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.

This has been tested on a qnap TS-119P II. Note that enabling WOL with
"ethtool -s eth0 wol g" is not enough; you also need to tell the PIC
microcontroller inside the qnap that WOL should be enabled by sending
0xF2 with qcontrol(1) and you have to disable EUP ("Energy-using
