afdafff130 netxen: use module parameter correctly
Netxen driver is doing this bogus thing to create a control file.
This fails if device doesn't exist, and overall is a bad way to do
the module parameter. Rather than fix borked code, just rewrite.
Just using a writeable module parameter of 0/1 is the correct way

o Don't increment refernce count, if start_firmware fails

o Clear __NX_RESETTING bit, incase of fatal error or tempeature

f58dbd7320 netxen : fix debug tools access for NX2031
Driver maps only some part of the MMIO bar 0 in case of

When debug tools need to access resources in
unmapped regions, driver needs to map these on the fly
in order to complete read/write request.

5d09e534bb netxen : fix BOND_MODE_TLB/ALB mode.
o Along with netdev->perm_addr, mac address will be
  maintained in device private structure.

o Device limitation: We need to set mac address when ever
  interface comes up.

In ALB/TAL mode, bonding driver calls set_mac for all slave with bond mac address.
But bonding driver set netdev->dev_addr field to its original value,
after enslaving interfaces.

When ever active slave changes, it swap dev_addr of inactive slave with active.
Yet it doesn't notify driver about change in netdev->dev_addr.

As netxen driver need to set mac addr when ever interface comes up,
it can't rely on netdev->dev_addr field. Specially in case of bonding mode ALB/TLB.
