Adds support for extended window size (EWS) config option. We enable EWS
feature in L2CAP Info RSP when hs enabled. EWS option is included in L2CAP
Config Req if tx_win (which is set via socket) bigger then standard default
value (63) && hs enabled && remote side supports EWS feature.
Using EWS selects extended control field in L2CAP.
Code partly based on Qualcomm and Atheros patches sent upstream a year ago.

ip_vs_mutext is used by both netns shutdown code and startup
and both implicit uses sk_lock-AF_INET mutex.

ip_vs_dst_event() ip_vs_genl_set_cmd()
sk_lock-AF_INET __ip_vs_mutex
sk_lock-AF_INET
__ip_vs_mutex
* DEAD LOCK *
A new mutex placed in ip_vs netns struct called sync_mutex is added.
Comments from Julian and Simon added.
This patch has been running for more than 3 month now and it seems to work.
Ver. 3
IP_VS_SO_GET_DAEMON in do_ip_vs_get_ctl protected by sync_mutex
instead of __ip_vs_mutex as sugested by Julian.

We can now move the radiotap header parsing into
ieee80211_monitor_start_xmit(). This moves it out of
the hotpath, and also helps the code since now the
radiotap header will no longer be present in
ieee80211_xmit() etc. which is easier to understand.

The purpose of this is two-fold:
1) by moving it out of tx_data.flags, we can in
another patch move the radiotap parsing so it
no longer is in the hotpath
2) if a device implements fragmentation but can
optionally skip it, the radiotap request for
not doing fragmentation may be honoured

To avoid ifdefs in the other code that supports DCB notifiers
add stub routines. This method seems popular in other net code
for example 8021Q.

Use ifindex instead of ifname in the DCB app ring. This makes for a smaller
data structure and faster comparisons. It also avoids possible issues when
a net device is renamed.
