The first wrb seen by tx compl processing does not have a dma handle in it.
Currently, pci_unmap_single() is attempted on this wrb and pci_unmap_page() on the
rest. So, pci_unmap_page() gets incorrectly called on the dma hdl of skb->data (that
was mapped using map_single()). This patch fixes this issue.

The request to create an mccq was being dispatched without
doing a byte swap of num_pages. This byte swap is necessary
for Big Endian systems like PPC. Not having this fix leads
mccq create to fail on BE ASICs running newer version of
firmware, thereby causing driver initialization failure.

When PCI functions are virtuialized in applications by assigning PCI
functions to VM (PCI passthrough), the be2net driver in the VM sees a

different function number. So, use of PCI function number in any
calculation will break existing code. This patch takes care of it.

In tx/mcc polling, napi_complete() is being incorrectly called
before reaping tx completions. This can cause tx compl processing
to be scheduled on another cpu concurrently which can result in a panic.
This if fixed by calling napi complete() after tx/mcc compl processing
but before re-enabling interrupts (via a cq notify).

When an MCC cmd is issued (via a netdev/ethtool op)
while the device is not open, the MCC CQ gets processed but the EQ
is not processed (as isr is not registered.) This can cause the EQ
to become full. So, while the device is not open, CQ must not be re-armed
to prevent EQ entries.
