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.

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 patch implements a low latency Write Combining (aka Write Coalescing) work
request path. PCIE maps User Space Doorbell BAR2 region writes to the new

Virtual functions don't have access to HW registers, therefore most ethtool ops
are forbidden to them. Instead of checking in each op whether the device being
driven is a virtual function or a physical function, this patch creates a
separate ethtool ops struct for virtual functions and uses it to initialize
the ethtool ops of the driver in case it is driving a virtual function device.

Ben Hutchings says:
====================
1. Merge sfc changes (only) accepted for 3.9.
2. PTP improvements from Laurence Evans.
3. Overhaul of RX buffer management:
- Always allocate pages, and enable scattering where possible
- Fit as many buffers as will fit into a page, rather than limiting to 2
- Introduce recycle rings to reduce the need for IOMMU mapping and
unmapping
4. PCI error recovery (AER and EEH) implementation.
5. Fix a bug in RX filter replacement.
6. Fix configuration with 1 RX queue in the PF and multiple RX queues in
VFs.
