This fixes interrupt-related issue when no
interfaces were running thus the device was
considered powered down.
The power_down() function isn't really powering
down the device. It simply assumed it won't
interrupt. This wasn't true in some cases and
could lead to paging failures upon FW indication
interrupt (i.e. FW crash) because some structures
aren't allocated in that device state.
One reason for that was that ar_pci->started
wasn't reset. The other is interrupts should've
been masked when teardown starts.
The patch reorganized interrupt setup and makes
sure ar_pci->started is reset accordingly.

If the device is removed and hotplug fails
ioread32() will return 0xFFFFFFFF. In that case
reading ringbuffer during device bringup led to
out-of-bounds addressing of a ringbuffer array
that in turn led to a paging failure.
This could be reproduced by the following:
* boot without acpi/prevent hotplug from working
* insert and manually detect (pci rescan) the device
* remove the device physically
* load ath10k driver
* kernel crashed

Before sending command to firmware, we need to check the frame type.
We skip registering the mgmt frame that has already been registered.

In function 'mwifiex_write_data_complete' it need tx info to find
the mwifiex_private to updates statistics and wake up tx queues.
Or we may trigger tx queues timeout when transmitting lots of mgmt
frames.

Delete packets from TX queues for this mwifiex_private structure
when bridged packet count reaches maximum threshold. Bridged packets
from each RA List are deleted till they fall to low threshold of 128.

Maintain total outstanding packet count for RA list instead of total

pkt_count is used to determine if BA can be formed on this RA list
by comparing it with randomly generated BA threshold. The pkt_count
variable name here is ambiguous and does not reflect its usage
correctly. Rename it to ba_pkt_count.

Under uAP mode mwifiex may stop all net tx queues on forwarding
packets. This may stop some tx queues and they never have chance
to be waked up. There is also no need to check tx_pending and
stop queues here. Because local host has such kind of check when
transmitting packets and it's not proper to have forwarding affect
local transmitting.

Steinar reported reallocations of skb->head with IPv6, leading to
a warning in skb_try_coalesce()
It turns out iwl3945 has several problems :
1) skb->truesize is underestimated.
We really consume PAGE_SIZE bytes for a fragment,
not the frame length.
2) 128 bytes of initial headroom is a bit low and forces reallocations.
3) We can avoid consuming a full page for small enough frames.

Add support for TCP and UDP HW checksum offloading.
RX chain is allways configured for offload mode.
In case of checksum error in RX path the DMA L4 error bit(5)
will be set to 1 and driver will drop the packet.
TX checksum offloading is configrable (ethtool -K).
TX descriptors are configured for checksum offload according
to the SKB protocol type (TCP/UDP, IPV4/6), Upon mismatch drop
the TX packet (checksum required but not TCP/UDP IPV4/6 type).
