This local var is protected by all sorts of bluetooth debugging

pr_debug() evaluates it's args only if either DEBUG or
CONFIG_DYNAMIC_PRINTK_DEBUG is defined.

Solving this inside of the BT_DBG() macro is non-trivial since

dccp ccid-2: Phase out the use of boolean Ack Vector sysctl

This removes the use of the sysctl and the minisock variable for the Send Ack
Vector feature, as it now is handled fully dynamically via feature negotiation
(i.e. when CCID-2 is enabled, Ack Vectors are automatically enabled as per
 RFC 4341, 4.).

Using a sysctl in parallel to this implementation would open the door to
crashes, since much of the code relies on tests of the boolean minisock /
sysctl variable. Thus, this patch replaces all tests of type

if (dccp_msk(sk)->dccpms_send_ack_vector)
/* ... */
with
if (dp->dccps_hc_rx_ackvec != NULL)
/* ... */

The dccps_hc_rx_ackvec is allocated by the dccp_hdlr_ackvec() when feature
negotiation concluded that Ack Vectors are to be used on the half-connection.
Otherwise, it is NULL (due to dccp_init_sock/dccp_create_openreq_child),
so that the test is a valid one.

The activation handler for Ack Vectors is called as soon as the feature
negotiation has concluded at the
 * server when the Ack marking the transition RESPOND => OPEN arrives;
 * client after it has sent its ACK, marking the transition REQUEST => PARTOPEN.

Adding the sequence number of the Response packet to the Ack Vector has been
removed, since
 (a) connection establishment implies that the Response has been received;
 (b) the CCIDs only look at packets received in the (PART)OPEN state, i.e.
     this entry will always be ignored;
 (c) it can not be used for anything useful - to detect loss for instance, only
     packets received after the loss can serve as pseudo-dupacks.

There was a FIXME to change the error code when dccp_ackvec_add() fails.
I removed this after finding out that:
 * the check whether ackno < ISN is already made earlier,
 * this Response is likely the 1st packet with an Ackno that the client gets,
 * so when dccp_ackvec_add() fails, the reason is likely not a packet error.

dccp: Remove manual influence on NDP Count feature

Updating the NDP count feature is handled automatically now:
 * for CCID-2 it is disabled, since the code does not use NDP counts;
 * for CCID-3 it is enabled, as NDP counts are used to determine loss lengths.

Allowing the user to change NDP values leads to unpredictable and failing
behaviour, since it is then possible to disable NDP counts even when they
are needed (e.g. in CCID-3).

This means that only those user settings are sensible that agree with the
values for Send NDP Count implied by the choice of CCID. But those settings
are already activated by the feature negotiation (CCID dependency tracking),
hence this form of support is redundant.

At startup the initialisation of the NDP count feature uses the default
value of 0, which is done implicitly by the zeroing-out of the socket when
it is allocated. If the choice of CCID or feature negotiation enables NDP
count, this will then be updated via the NDP activation handler.

 2. When feature negotiation fails, the socket should be marked as not usable,

    setting the socket state to CLOSED, returning with ECOMM in sk_err.

iwl3945 : Fix a-band association for passive channels

Patch does following things
    1) This patch fixes the a-band association for passive channels with new
    uCode feature that it allows direct scan on passive channels after
    auto-switch from passive to active. This enables sending of direct probes
    on passive channels, as long as some traffic is detected on that channel.
    This improves the scanning for hidden SSIDs in A-band,which is all
    passive channels.

    This patch fixes the bug no 1748.

        http://www.intellinuxwireless.org/bugzilla/show_bug.cgi?id=1748

    2) This fix will only work with uCode version 15.28.2.8 and above.
    Prior versions of uCode would work only if we heard the traffic within
     active dwell time, which is much shorter than passive dwell time and
    is shorter than typical beacon periods. This patch also provids full
    active dwell time even if we hear traffic late in passive dwell.

    3) uCode API version is incremented to 2.
