We recently made loopback a bool type instead of an int, so the bitwise
AND is redundent.

Change details:
- Add debugfs support to obtain firmware trace, saved firmware trace on
an IOC crash, driver info and read/write to registers.
- debugfs hierarchy:
bna/pci_dev:<pci_name>
where the pci_name corresponds to the one under /sys/bus/pci/drivers/bna
- Following are the new debugfs entries added:
fwtrc: collect current firmware trace.
fwsave: collect last saved fw trace as a result of firmware crash.
regwr: write one word to chip register
regrd: read one or more words from chip register.
drvinfo: collect the driver information.

This patch adds the PCI support (as EXPERIMENTAL)
this has been also tested on XLINX XC2V3000 FF1152AMT0221

To support the PCI bus the main part has been reworked
and both the platform and the PCI specific parts have

The NETIUCV device driver allows to connect a Linux guest on z/VM to
another z/VM guest based on the z/VM communication facility IUCV.
Multiple output paths to different guests are possible, as well as
multiple input paths from different guests.
With this feature, you can configure multiple point-to-point NETIUCV
interfaces between your Linux on System z instance and another z/VM
guest.

module_param(bool) used to counter-intuitively take an int. In
fddd5201 (mid-2009) we allowed bool or int/unsigned int using a messy
trick.
It's time to remove the int/unsigned int option. For this version
it'll simply give a warning, but it'll break next kernel version.

This patch adds the ethtool callbacks necessary to change the rss
indirection table from userspace. Should the number of interrupts
change (e.g. across a close / open call, or through a reset) and
any one of the indirection table values fall out-of-range, the driver
will reset the indirection table to a default layout.
[Integrated many suggestions made by Ben Hutchings.]

Lancer does not have HW registers to indicate the EQ causing the INTx

New FW can give clues to driver regarding default port type
and whether or not we should default to link sensing on the port.
2 bits are added to QUERY_PORT command:
1. suggested_type: This bit gives a hint whether the default port type should be
IB or Ethernet.
The driver will use this hint in case the user didn't specify explicitly the link layer
type he wants to set.
2. default_sense: If this bit is set, we would sense the port type on start-up
and default the port to link sensing

All drivers that support modification of the RX flow hash indirection
table initialise it in the same way: RX rings are assigned to table
entries in rotation. Make that default policy explicit by having them
call a ethtool_rxfh_indir_default() function.
In the ethtool core, add support for a zero size value for
ETHTOOL_SRXFHINDIR, which resets the table to this default.
