The PF driver is incorrectly resetting Octeon when the module parameter
"fw_type=none" is there. "fw_type=none" means the PF should not load any
firmware to the NIC because Octeon is already running preloaded firmware.
Fix it by putting an if (fw_type != none) around the reset code.
Because the Octeon reset is now conditionally gone, when unloading the
driver, conditionally send the RESET_PF command to the firmware who will
then free up PF-related data structures.

Change to support host<->firmware command return value.
Fix for vf mac addr state command.
1. Added support for firmware commands to return a value:
- previously, the returned code overlapped with host codes, thus
commands were only returning 0 (success) or -1 (interpreted as
timeout)
- per 'response_manager.h', the error codes are split into two fields
(major/minor) now, firmware commands are grouped into their own
'major' group, separate from the host's 'major' group, which allow f/w
commands to return any 16-bit value
2. The command to set vf mac addr was logging a success message even if
command failed. Now command uses a callback function to log the status
message.
3. The command to set vf mac addr was not logging a message when set via
the host 'ip' command. Now, the callback function will log an
appropriate message.

All IRQs owned by the PF and VF drivers share the same nondescript name
"octeon"; this makes it difficult to setup interrupt affinity.
Change the IRQ names to reflect their specific purpose:
LiquidIO<id>-<func>-<type>-<queue pair num>
Examples:
LiquidIO0-pf0-rxtx-3
LiquidIO1-vf1-rxtx-0
LiquidIO0-pf0-aux
We cannot use netdev->name for naming the IRQs because:
1. Early during init, the PF and VF drivers require interrupts to
send/receive control data from the NIC firmware; so the PF and VF
must request IRQs long before the netdev struct is registered.
2. The IRQ name can only be specified at the time it is requested.
It cannot be changed after that.

The network stack no longer uses the last_rx member of struct net_device
since the bonding driver switched to use its own private last_rx in
commit 9f24273837 ("bonding: use last_arp_rx in slave_last_rx()").
However, some drivers still (ab)use the field for their own purposes and
some driver just update it without actually using it.
Previously, there was an accompanying comment for the last_rx member
added in commit 4dc89133f4 ("net: add a comment on netdev->last_rx")
which asked drivers not to update is, unless really needed. However,
this commend was removed in commit f8ff080dac ("bonding: remove
useless updating of slave->dev->last_rx"), so some drivers added later
on still did update last_rx.
Remove all usage of last_rx and switch three drivers (sky2, atp and
smc91c92_cs) which actually read and write it to use their own private
copy in netdev_priv.
Compile-tested with allyesconfig and allmodconfig on x86 and arm.

alloc_workqueue replaces deprecated create_workqueue().
A dedicated workqueue has been used since the workitem viz
(&lio->txq_status_wq.wk.work which maps to octnet_poll_check_txq_status)
is involved in a brief poll routine for checking transmit queue status
and is an intergral part of normal device operation.
WQ_MEM_RECLAIM has been set to guarantee forward progress under memory
pressure, which is a requirement here.
Since there are only a fixed number of work items, explicit concurrency
limit is unnecessary.
flush_workqueue is unnecessary since destroy_workqueue() itself calls
drain_workqueue() which flushes repeatedly till the workqueue
becomes empty.

The return value of vmalloc on failure of allocation of memory should
be -ENOMEM and not -1.
Found using Coccinelle. A simplified version of the semantic patch
used is:
//<smpl>
@@
expression *e;
identifier l1;
position p,q;
@@
e@q = vmalloc(...);
if@p (e == NULL) {
...
goto l1;
}
l1:
...
return -1
+ -ENOMEM
;
//</smpl
The single call site of the containing function checks whether the
returned value is -1, so this check is changed as well. The single call
site of this call site, however, only checks whether the value is not 0,
so no further change was required.
