This patch replaces the variable name data with the variable name features
for ixgbe_fix_features and ixgbe_set_features. This helps to make some
issues more obvious such as the fact that we were disabling Rx VLAN tag
stripping when we should have been forcing it to be enabled when DCB is
enabled.
In addition there was deprecated code present that was disabling the LRO
flag if we had the itr value set too low. I have updated this logic so
that we will now allow the LRO flag to be set, but will not enable RSC
until the rx-usecs value is high enough to allow enough time for Rx packet
coalescing.

The optimal management of VMID depends on a number of factors which vary
dynamically at runtime, for example the connection to a system docking
station. In some circumstances it is desirable to keep VMID enabled all
the time, in others it is desirable to aggressively power it up and down.
Provide a callback allowing machine driver to configure either the normal
power up/down mode (WM8994_VMID_MODE_NORMAL) or to maintain VMID even
when idle (WM8994_VMID_MODE_FORCE). This callback, wm8994_vmid_mode(),
should be called with the CODEC lock.

There are couple places where we check unsigned values for negative. I
changed ->gpin_nr to signed because in gpio_ir_recv_probe() we do:
if (pdata->gpio_nr < 0)
return -EINVAL;
I also change gval to a signed int in gpio_ir_recv_irq() because that's
the type that gpio_get_value_cansleep() returns and we test for negative
returns.

The problem is that for the case of priority queues, we
have to assume that __rpc_remove_wait_queue_priority will move new
elements from the tk_wait.links lists into the queue->tasks[] list.
We therefore cannot use list_for_each_entry_safe() on queue->tasks[],
since that will skip these new tasks that __rpc_remove_wait_queue_priority
is adding.
Without this fix, rpc_wake_up and rpc_wake_up_status will both fail
to wake up all functions on priority wait queues, which can result
in some nasty hangs.

Ryley and me tested several eLNA configuration values with both a rooftop
and a portable antenna.
Ryley fuond out that the best value for his Elgato stick is indeed the current
default value 0xC0.
Instead, my stick is not capable of tuning VHF channels with 0xC0. With 0x80,
VHF works but the tuner sensitivity with the portable antenna is poor.
Instead, the value 0xA0 works with VHF and also gives good performance with
both the rooftop and the portable antenna.
So we concluded that devices built on the reference design work best with 0xA0,
while custom designs (Elgato, PCTV) seem to require 0xC0.
I also removed the unused parameter "minor" in struct as102_dev_t.

This patch fixes a regression in kernel 3.3 due to this patch:
http://patchwork.linuxtv.org/patch/8332/
That patch changes "#pragma pack(1)" with "__packed" attributes, but it is not
complete. In fact, in the as102 driver there are a lot of structs/unions
defined inside other structs/unions.
When the "__packed" attribute is applied only on the external struct, it will
not affect the internal struct definitions.
So the regression is fixed by specifiying the "__packed" attribute also on the
internal structs.
This patch should go into 3.3, as it fixes a regression introduced in the new
kernel version.

In cx231xx_v4l2_close() there are two calls to
cx231xx_release_resources(dev) followed by kfree(dev). That is a
problem since cx231xx_release_resources() already kfree()'s its
argument, so we end up doing a double free.
Easily resolved by just removing the redundant kfree() calls after the
calls to cx231xx_release_resources().
I also changed the 'dev = NULL' assignments (which are rather
pointless since 'dev' is about to go out of scope), to 'fh->dev = NULL'
since it looks to me that that is what was actually intended.
And I removed the 'dev = NULL' assignment at the end of
cx231xx_release_resources() since it is pointless.
