Ooiwa Naohiro 7959ea254e bnx2: Fix the behavior of ethtool when ONBOOT=no
I found a little bug.

When configure in ifcfg-eth* is ONBOOT=no,
the behavior of ethtool command is wrong.

    # grep ONBOOT /etc/sysconfig/network-scripts/ifcfg-eth2
    ONBOOT=no
    # ethtool eth2 | tail -n1

Jiri Pirko 31278e7147 net: group address list and its count
This patch is inspired by patch recently posted by Johannes Berg. Basically what
my patch does is to group list and a count of addresses into newly introduced
structure netdev_hw_addr_list. This brings us two benefits:
1) struct net_device becames a bit nicer.
2) in the future there will be a possibility to operate with lists independently
   on netdevices (with exporting right functions).
I wanted to introduce this patch before I'll post a multicast lists conversion.

Eric Dumazet 042a53a9e4 net: skb_shared_info optimization
skb_dma_unmap() is quite expensive for small packets,
because we use two different cache lines from skb_shared_info.

One to access nr_frags, one to access dma_maps[0]

Instead of dma_maps being an array of MAX_SKB_FRAGS + 1 elements,
let dma_head alone in a new dma_head field, close to nr_frags,
to reduce cache lines misses.

Tested on my dev machine (bnx2 & tg3 adapters), nice speedup !

Jiri Pirko ccffad25b5 net: convert unicast addr list
This patch converts unicast address list to standard list_head using
previously introduced struct netdev_hw_addr. It also relaxes the
locking. Original spinlock (still used for multicast addresses) is not
needed and is no longer used for a protection of this list. All
reading and writing takes place under rtnl (with no changes).

I also removed a possibility to specify the length of the address
while adding or deleting unicast address. It's always dev->addr_len.

The convertion touched especially e1000 and ixgbe codes when the
change is not so trivial.

Now that core network takes care of trans_start updates, dont do it

Eric Dumazet d62fda082c bnx2: bnx2_tx_int() optimizations
When using bnx2 in a high transmit load, bnx2_tx_int() cost is pretty high.

There are two reasons.

One is an expensive call to bnx2_get_hw_tx_cons(bnapi) for each freed skb

One is cpu stalls when accessing skb_is_gso(skb) / skb_shinfo(skb)->nr_frags
because of two cache line misses.
(One to get skb->end/head to compute skb_shinfo(skb),
 one to get is_gso/nr_frags)

This patch :

1) avoids calling bnx2_get_hw_tx_cons(bnapi) too many times.

2) makes bnx2_start_xmit() cache is_gso & nr_frags into sw_tx_bd descriptor.
   This uses a litle bit more ram (256 longs per device on x86), but helps a lot.

3) uses a prefetch(&skb->end) to speedup dev_kfree_skb(), bringing
  cache line that will be needed in skb_release_data()

result is 5 % bandwidth increase in benchmarks, involving UDP or TCP receive
 & transmits, when a cpu is dedicated to ksoftirqd for bnx2.

bnx2_tx_int going from 3.33 % cpu to 0.5 % cpu in oprofile

Note : skb_dma_unmap() still very expensive but this is for another patch,
not related to bnx2 (2.9 % of cpu, while it does nothing on x86_32)

Michael Chan 581daf7e00 bnx2: Fix panic in bnx2_poll_work().
Add barrier() to bnx2_get_hw_{tx|rx}_cons() to fix this issue:

http://bugzilla.kernel.org/show_bug.cgi?id=12698

This issue was reported by multiple i386 users.  Without barrier(),
the compiled code looks like the following where %eax contains the
address of the tx_cons or rx_cons in the DMA status block.  The
status block contents can change between the cmpb and the movzwl
instruction.  The driver would crash if the value was not 0xff during
the cmpb instruction, but changed to 0xff during the movzwl
instruction.

6828:	80 38 ff             	cmpb   $0xff,(%eax)
682b:	0f b7 10             	movzwl (%eax),%edx

With the added barrier(), the compiled code now looks correct:

683d:	0f b7 10             	movzwl (%eax),%edx
6840:	0f b6 c2             	movzbl %dl,%eax
6843:	3d ff 00 00 00       	cmp    $0xff,%eax

Thanks to Pascal de Bruijn <pmjdebruijn@pcode.nl> for reporting the
problem and Holger Noefer <hnoefer@pironet-ndh.com> for patiently

Michael Chan 6901031372 bnx2: Fix problem of using wrong IRQ handler.
The MSI-X handler was chosen before the call to pci_enable_msix().
If MSI-X was not available, the wrong MSI-X handler would be used in

INTA would not be cleared by the MSI-X handler.

Fixed by assigning MSI-X handler after pci_enable_msix() returns

Michael Chan efba01803c bnx2: Add workaround to handle missed MSI.
The bnx2 chips do not support per MSI vector masking.  On 5706/5708, new MSI
address/data are stored only when the MSI enable bit is toggled.  As a result,
SMP affinity no longer works in the latest kernel.  A more serious problem is
that the driver will no longer receive interrupts when the MSI receiving CPU
goes offline.

The workaround in this patch only addresses the problem of CPU going offline.
When that happens, the driver's timer function will detect that it is making
no forward progress on pending interrupt events and will recover from it.

Eric Dumazet reported the problem.

We also found that if an interrupt is internally asserted while MSI and INTA
are disabled, the chip will end up in the same state after MSI is re-enabled.
The same workaround is needed for this problem.

Michael Chan 5ec6d7bf19 bnx2: Restrict WoL support.
On some quad-port cards that cannot support WoL on all ports due
to excessive power consumption, the driver needs to restrict WoL
on some ports by checking VAUX_PRESET bit.

David S. Miller babcda74e9 drivers/net: Kill now superfluous ->last_rx stores.
The generic packet receive code takes care of setting
netdev->last_rx when necessary, for the sake of the
bonding ARP monitor.

Drivers need not do it any more.

Some cases had to be skipped over because the drivers
were making use of the ->last_rx value themselves.

Johannes Berg e174961ca1 net: convert print_mac to %pM
This converts pretty much everything to print_mac. There were
a few things that had conflicts which I have just dropped for
now, no harm done.

I've built an allyesconfig with this and looked at the files
that weren't built very carefully, but it's a huge patch.

Benjamin Li 3d16af8665 bnx2: Handle DMA mapping errors.
Before, the driver would not care about the return codes from pci_map_*
functions.  This could be potentially dangerous if a mapping failed.
Now, we will check all pci_map_* calls.  On the transmit side, we switch
to use the new function skb_dma_map().  On the receive side, we add
pci_dma_mapping_error().
