The fatal error task can be scheduled while processing an offload packet
in NAPI context when the connection handle is bogus. this can race
with the ports being brought down and the cxgb3 workqueue being flushed.
Stop napi processing before flushing the work queue.

The ULP drivers (iSCSI, iWARP) might also schedule a task on keventd_wk
while releasing a connection handle (cxgb3_offload.c::cxgb3_queue_tid_release()).
The driver however does not flush any work on keventd_wq while being unloaded.
This patch also fixes this.

Also call cancel_delayed_work_sync in place of the the deprecated
cancel_rearming_delayed_workqueue.

After calling skb_gro_receive skb->len can no longer be relied
on since if the skb was merged using frags, then its pages will
have been removed and the length reduced.

This caused tcp_gro_receive to prematurely end merging which

Suppose that we receive lots of frames, start processing them, but
exhaust our budget so that we return before we had a chance to look
at all of them.

Then, when the network layer calls us again, we will only continue
processing the buffers if the REC bit was set in the mean time, which it
might not be if there was a brief pause in the flow of packets. If this
happens, we'll simply display a warning and call netif_rx_complete()
with potentially lots of unprocessed packets in the RX ring...

Fix this by scanning the ring no matter what flags are set in the
interrupt status register.

The removal of the SAME target accidentally removed one feature that is
not available from the normal NAT targets so far, having multi-range
mappings that use the same mapping for each connection from a single
client. The current behaviour is to choose the address from the range
based on source and destination IP, which breaks when communicating
with sites having multiple addresses that require all connections to
originate from the same IP address.

Introduce a IP_NAT_RANGE_PERSISTENT option that controls whether the
destination address is taken into account for selecting addresses.

mac80211: Fragmentation threshold (typo)

ieee80211_ioctl_siwfrag() sets the fragmentation_threshold to 2352

In a scenario where there isn't any firmware available, we will have a
double kfree of rt2x00dev->spec.channels_info when ieee80211_register_hw
returns an error status inside rt2x00lib_probe_hw.

The problem is that if ieee80211_register_hw fails, we call
rt2x00lib_remove_hw twice:
* first inside rt2x00lib_probe_hw upon failure of ieee80211_register_hw
* error status is returned to rt2x00lib_probe_dev, which then sees it and
  calls in this case rt2x00lib_remove_dev that will again run
  rt2x00lib_remove_hw

Prevent this avoiding calling rt2x00lib_remove_hw inside
rt2x00lib_probe_hw

Problem was detected with CONFIG_DEBUG_PAGEALLOC=y, CONFIG_SLUB_DEBUG=y,
CONFIG_SLUB_DEBUG_ON=y, that dumps this with no firmware available:

Wext makes no assumptions about the contents of
data->txpower.fixed and data->txpower.value when
data->txpower.disabled is set, so do not update
the user-requested power level while disabling.

Also, when wext configures a really _fixed_ power
output [1], we should reject it instead of limiting it
to the regulatory constraint. If the user wants to set
a _limit_ [2] then we should honour that.

[1] iwconfig wlan0 txpower 20dBm fixed
[2] iwconfig wlan0 txpower 10dBm

This fixes
