When using module options arp monitoring and balance-alb/balance-tlb
are mutually exclusive options. Anytime balance-alb/balance-tlb are
enabled mii monitoring is forced to 100ms if not set. When configuring
via sysfs no checking is currently done.
Handling these cases with sysfs has to be done a bit differently because
we do not have all configuration information available at once. This
patch will not allow a mode change to balance-alb/balance-tlb if
arp_interval is already non-zero. It will also not allow the user to
set a non-zero arp_interval value if the mode is already set to
balance-alb/balance-tlb. They are still mutually exclusive on a
first-come, first serve basis.
Tested with initscripts on Fedora and manual setting via sysfs.

Fix possible double priv->mutex lock introduced by commit
a69b03e941
"iwlwifi: cancel scan watchdog in iwl_bg_abort_scan" .
We can not call cancel_delayed_work_sync(&priv->scan_check) with
priv->mutex locked because workqueue function iwl_bg_scan_check()
take that lock internally.
We do not need to synchronize when canceling priv->scan_check work.
We can avoid races (sending double abort command or send no
command at all) using STATUS_SCAN_ABORT bit. Moreover
current iwl_bg_scan_check() code seems to be broken, as
we should not send abort commands when currently aborting.

For some drivers it can be useful to know whether the channel they're
supposed to switch to is going to be used for short off-channel work or
scanning, or whether the hardware is expected to stay on it for a while
longer. This is important for various kinds of calibration work, which
takes longer to complete and should keep some persistent state, even if
the channel temporarily changes.

This reverts this commit. While in theory the change is
correct the patch does not address current assumptions made
by some drivers, one which is definitley affected is ath9k.
Prior to this change the scan complete callback would be
called after we returned to the home channel and configured
the hardware RX filters. After this change we call the scan
complete callback prior to both the hw config and the config
filter. At least for ath9k this breaks quite a few assumptions
on the callback, leading to disconnects to the AP after every scan
making the driver pretty useless on STA mode. The goal behind
this commit was to address the now understood spurious warnings
from ath9k and mac80211_hwsim on scanning on two wiphys at the
same time but we have now supressed these and will address this
issue in the next kernel release.
When fixing this for good next we must first review the other
driver's dependence on this logic and perhaps consider removal
of the scan complete callback all together.
