We should prefer `struct pci_device_id` over `DEFINE_PCI_DEVICE_TABLE` to
meet kernel coding style guidelines. This issue was reported by checkpatch.
A simplified version of the semantic patch that makes this change is as
follows (http://coccinelle.lip6.fr/):
// <smpl>
@@
identifier i;
declarer name DEFINE_PCI_DEVICE_TABLE;
initializer z;
@@
- DEFINE_PCI_DEVICE_TABLE(i)
+ const struct pci_device_id i[]
= z;

net: get rid of SET_ETHTOOL_OPS
Dave Miller mentioned he'd like to see SET_ETHTOOL_OPS gone.
This does that.
Mostly done via coccinelle script:
@@
struct ethtool_ops *ops;
struct net_device *dev;
@@
- SET_ETHTOOL_OPS(dev, ops);
+ dev->ethtool_ops = ops;
Compile tested only, but I'd seriously wonder if this broke anything.

The conflicts were minor:
1) sit.c changes overlap with change to ip_tunnel_xmit() signature.
2) br_multicast.c had an overlap between computing max_delay using
msecs_to_jiffies and turning MLDV2_MRC() into an inline function
with a name using lowercase instead of uppercase letters.
3) stmmac had two overlapping changes, one which conditionally allocated

and another one handling store-and-forward DMA made. The latter of
which should not go into the new of_find_property() basic block.

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.

phase, in netxen_release_tx_buffer(), using full size TSO packets.
cmd_buf->frag_count includes the skb->data part, so the loop must

Christoph provided the fixes in netxen_map_tx_skb() function.

o Linux stack estimates MSS from skb->len or skb_shinfo(skb)->gso_size.
In case of LRO skb->len is aggregate of len of number of packets hence MSS
obtained using skb->len would be incorrect. Incorrect estimation of recv MSS
would lead to delayed acks in some traffic patterns (which sends two or three
packets and wait for ack and only then send remaining packets). This leads to
drop in performance. Hence we need to set gso_size to MSS obtained from firmware.
o This is fixed recently in firmware hence the MSS is obtained based on
capability. If fw is capable of sending the MSS then only driver sets the gso_size.
