a069ec9174 cxgb4: remove a bogus PCI function number check
Remove a bogus PCI function number check from the driver's .remove
method that causes pci_release_regions not to be called for function 0
if additional functions are attached and one of them is used as primary.

e46dab4d4b cxgb4: handle Rx/Tx queue ranges not starting at 0
Currently the driver assumes that queue IDs start at 0 but that's true
only for function 0.  To support operation on other functions get the
start of the queue ranges from FW and offset accordingly.

060e0c752b cxgb4: support running the driver on PCI functions besides 0
Add support for running the driver on any PCI function.  Mostly this
entails replacing a constant 0 in a number of calls with the variable

Get info about the availability of Tx on-chip queues from FW and if they
are supported set up a memory window for them.  iw_cxgb4 will be using them.
Move the existing window setup later in the init sequence, after we have

835bb606fa cxgb4: exclude registers with read side effects from register dumps
A few registers have side effects on reads, eg FIFO pointers that
auto advance or mailboxes which change ownership when read.  They are
unsafe to read so exclude them from ethtool register dumps.

Bump ethtool_regs.version to indicate the changed register set.

1437ce3983 ethtool: Change ethtool_op_set_flags to validate flags
ethtool_op_set_flags() does not check for unsupported flags, and has
no way of doing so.  This means it is not suitable for use as a
default implementation of ethtool_ops::set_flags.

Add a 'supported' parameter specifying the flags that the driver and
hardware support, validate the requested flags against this, and
change all current callers to pass this parameter.

Change some other trivial implementations of ethtool_ops::set_flags to
call ethtool_op_set_flags().
