There are other kconfig symbols which use SCSI_FC_ATTRS.
In order to maintain sanity and prevent kconfig warnings, change
all of these from using 'select' to using 'depends on' so that
proper symbol dependencies will be honored and circular depends
problems will be avoided.
This fixes kconfig warnings and build errors:

Reported by Nikolay Aleksandrov.  In efx_init_port() we call
 efx_mac_reconfigure() to work around a Falcon/A1 limitation, and this calls
 efx_{arch}_filter_sync_rx_mode(), which takes the addr_list_lock; but this
 lock is uninitialised, because we haven't called register_netdevice() yet.
So, in efx_farch_filter_sync_rx_mode(), check efx_dev_registered() before
 doing anything else.
The EF10 equivalent, efx_ef10_filter_sync_rx_mode(), already has the
 corresponding check.

The problem is that the slave is first linked and slave_cnt is
incremented afterwards leading to a div by zero in the modes that use it
as a modulus. What happens is that in bond_start_xmit()
bond_has_slaves() is used to evaluate further transmission and it becomes
true after the slave is linked in, but when slave_cnt is used in the xmit
path it is still 0, so fetch it once and transmit based on that. Since
it is used only in round-robin and XOR modes, the fix is only for them.
Thanks to Eric Dumazet for pointing out the fault in my first try to fix
this.

Signed-off-by: NDavid S. Miller <davem@davemloft.net>

In the current implementation the cleaning of tx ring is done by the
NAPI poll handler, which is scheduled after rx interrupts. Thus, in
absence of received packets the reclaim of used tx buffers is never
executed, blocking further transmission.

This can be easily reproduced starting the transmission of a UDP flow
with iperf, which blocks almost immediately because skbs are not
returned to the stack and the socket send buffer becomes full.

The patch enables tx interrupts so that the tx reclaim is scheduled
after completed transmissions.

This reverts commit 09ebb810.

ath9k_hw_set_sta_beacon_timers() configures AR_TIM_PERIOD with
the beacon interval. Before this commit, the sleepduration was
never greater than the beacon interval. But now, the behavior
has changed. For example, with an AP that uses a beacon interval of 100:

ath: phy9: next beacon 61128704
ath: phy9: beacon period 204800
ath: phy9: DTIM period 204800

If the sleepduration is calculated based on the listen time, then
the bmiss threshold should also be changed since the HW would
be in sleep state for a longer time, but that is not done currently.

To avoid configuring a higher beacon interval based on the sleepduration,
revert to the original behavior. Power consumption is not a
problem since PS is disabled in ath9k anyway.

The sunvnet driver does not have an rmb() in the ring consumer corresponding
to the wmb() in the producer. According to Documentation/memory-barriers.txt:

"When dealing with CPU-CPU interactions, certain types of memory barrier should
always be paired.  A lack of appropriate pairing is almost certainly an error."

In cases where an rmb() is not a no-op and a consumer is removing data from
the ring while a producer is adding new entries, a load reorder would allow

CPU1						CPU2
----						----
						LOAD desc.size [e.g]
STORE desc.size
<wmb>
set desc.hdr.state = VIO_DESC_READY
						LOAD desc.hdr.state
						[because VIO_DESC_READY, use
						 old desc.size, already loaded
						 out of order]

[CPU2 has reordered apparently unrelated LOADs]

To ensure other desc fields are not loaded before checking VIO_DESC_READY, we
need an rmb() between the check and desc data accesses.

I've also moved the viodbg() call to after the rmb() so that it, too, has
current descriptor data even with reordering, which has the side effect that
it won't print anything for descriptors that are not VIO_DESC_READY as before.
That's a) probably a good thing, since the fields are not necessarily set and,
b) better than adding another rmb() just for viodbg().

This would not be possible if strict-ordering is enforced, but then the
memory barriers should be no-ops in that case.

The idea here is to translate a value of 0 received from
the firmware to the lowest rssi figure. As rx_status->chain_signal
is a signed byte the lowest possible value is -128 and not -256.
-256 was causing 0 to get stored in the signed byte.

smps_mode is used uninitialized in a debug statement in AP
mode, so always initialize it.

While at it, fix a typo.

The latter is meant for software implementation of power
save and is not per-virtual interface. Since our driver
supports multiple virtual interfaces, we need to use
vif->bss_conf.dtim_period.

Using the LQ table which is initially set according to
the rssi could lead to EAPOLs being sent in high legacy
rates like 54mbps.
It's better to avoid sending EAPOLs in high rates as it reduces
the chances of a successful 4-Way handshake.
Avoid this and treat them like other mgmt frames which would
initially get sent at the basic rate.

When mac80211 requests multiple BSS config changes, as for example
while associating, we ignore power management and QoS changes and
only apply them later. Fix that by removing the "else" and making
the conditions independent.

Also move it after (potential) beacon filter enablement to have
that already enabled when going into power management code.

This code was broken on big endian systems. Sparse didn't
catch the bug since the firmware command was not tagged as
little endian.
Fix the bug for big endian systems and tag the field in the
firmware command to prevent such issues in the future.
