dccp: generalise data-loss condition
This patch generalises the task of determining data loss from RFC 4340, 7.7.1.
Let S_A, S_B be sequence numbers such that S_B is "after" S_A, and let
N_B be the NDP count of packet S_B. Then, using modulo-2^48 arithmetic,
D = S_B - S_A - 1 is an upper bound of the number of lost data packets,
D - N_B is an approximation of the number of lost data packets
(there are cases where this is not exact).
The patch implements this as
dccp_loss_count(S_A, S_B, N_B) := max(S_B - S_A - 1 - N_B, 0)

dccp: fix the adjustments to AWL and SWL
This fixes a problem and a potential loophole with regard to seqno/ackno
validity: currently the initial adjustments to AWL/SWL are only performed
once at the begin of the connection, during the handshake.
Since the Sequence Window feature is always greater than Wmin=32 (7.5.2),
it is however necessary to perform these adjustments at least for the first
W/W' (variables as per 7.5.1) packets in the lifetime of a connection.
This requirement is complicated by the fact that W/W' can change at any time
during the lifetime of a connection.
Therefore it is better to perform that safety check each time SWL/AWL are
updated, as implemented by the patch.
A second problem solved by this patch is that the remote/local Sequence Window
feature values (which set the bounds for AWL/SWL/SWH) are undefined until the
feature negotiation has completed.
During the initial handshake we have more stringent sequence number protection;
the changes added by this patch effect that {A,S}W{L,H} are within the correct
bounds at the instant that feature negotiation completes (since the SeqWin
feature activation handlers call dccp_update_gsr/gss()).

This patch changes the logic so that we call neigh_hh_init() with
neighbour lock read locked only, so that fast path can be run in

Commit 2ddaad397c47de012dfb956b0c05540da1a0dde5 entitled "tg3: Use
netif_set_real_num_{rx,tx}_queues()" added a new call to
netif_set_real_num_rx_queues in tg3_enable_msix(). This call also needs
to be added to the legacy path to correctly reflect the actual number of

cfg80211: fix BSS double-unlinking
When multiple interfaces are actively trying
to associate with the same BSS, they may both
find that the BSS isn't there and then try to
unlink it. This can cause errors since the
unlinking code can't currently deal with items
that have already been unlinked.
Normally this doesn't happen as most people
don't try to use multiple station interfaces
that associate at the same time too.
Fix this by using the list entry as a flag to
see if the item is still on a list.
