tcp: advertise MSS requested by user
I'm trying to use the TCP_MAXSEG option to setsockopt() to set the MSS
for both sides of a bidirectional connection.
man tcp says: "If this option is set before connection establishment, it
also changes the MSS value announced to the other end in the initial
packet."
However, the kernel only uses the MTU/route cache to set the advertised
MSS. That means if I set the MSS to, say, 500 before calling connect(),
I will send at most 500-byte packets, but I will still receive 1500-byte
packets in reply.
This is a bug, either in the kernel or the documentation.
This patch (applies to latest net-2.6) reduces the advertised value to
that requested by the user as long as setsockopt() is called before
connect() or accept(). This seems like the behavior that one would
expect as well as that which is documented.
I've tried to make sure that things that depend on the advertised MSS
are set correctly.

mac80211: fix virtual interfaces vs. injection
Currently, virtual interface pointers passed to drivers might be
from monitor interfaces and as such completely uninitialised
because we do not tell the driver about monitor interfaces when
those are created. Instead of passing them, we should therefore
indicate to the driver that there is no information; do that by
passing a NULL value and adjust drivers to cope with it.
As a result, some mac80211 API functions also need to cope with
a NULL vif pointer so drivers can still call them unconditionally.
Also, when injecting frames we really don't want to pass NULL all
the time, if we know we are the source address of a frame and have
a local interface for that address, we can to use that interface.
This also helps with processing the frame correctly for that
interface which will help the 802.11w implementation. It's not
entirely correct for VLANs or WDS interfaces because there the MAC
address isn't unique, but it's already a lot better than what we
do now.
Finally, when injecting without a matching local interface, don't
assign sequence numbers at all.

rfkill: remove transmitter blocking on suspend
Currently, rfkill would stand in the way of properly supporting wireless
devices that are capable of waking the system up from sleep or hibernation
when they receive a special wireless message. It would also get in the way
of mesh devices that need to remain operational even during platform
suspend.
To avoid that, stop trying to block the transmitters on the rfkill class
suspend handler.
Drivers that need rfkill's older behaviour will have to implement it by
themselves in their own suspend handling.
Do note that rfkill *will* attempt to restore the transmitter state on
resume in any situation. This happens after the driver's resume method is
called by the suspend core (class devices resume after the devices they are
attached to have been resumed).
The following drivers need to check if they need to explicitly block
