Michael Chan 41c2178adc bnx2: Read iSCSI config from shared memory during ->probe()
The scratchpad location that we were reading from has not been
initialized yet during ->probe(), so we were getting inaccurate
information.

Update version to 2.1.10.

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 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.

Benjamin Li 27ed9ddfde bnx2: Promote vector field in bnx2_irq structure from u16 to unsigned int
The bnx2 driver stores/uses the irq value from the pci_dev internally.
But when it stores the irq value, it has been performing an
integer demotion.  Because of the recent changes made to
arch/x86/kernel/io_apic.c, the new method in creating the irq value
(using build_irq_for_pci_dev()) has exposed this bug on x86 systems.

Because of this demotion when calling request_irq() from
bnx2_request_irq(), the driver would get a return code of -EINVAL.
This is because the kernel could not find the requested irq descriptor.
By storing the irq value properly, the kernel can find the correct
irq descriptor and the bnx2 driver can operate normally.

Michael Chan 35e9010b22 bnx2: Put tx ring variables in a separate struct.
In preparation for multi-ring support, tx ring variables are now put
in a separate bnx2_tx_ring_info struct.  Multi tx ring will not be
enabled until it is fully supported by the stack.  Only 1 tx ring
will be used at the moment.

The functions to allocate/free tx memory and to initialize tx rings
are now modified to handle multiple rings.
