Bluetooth: Prevent transparent SCO on older devices

Older Bluetooth devices may not support Setup Synchronous Connection or
SCO transparent data. This is indicated by the corresponding LMP feature
bits. It is not possible to know if the adapter support these features
before setting BT_VOICE option since the socket is not bound to an
adapter. An adapter can also be added after the socket is created. The
socket can be bound to an address before adapter is plugged in.

Thus, on a such adapters, if user request BT_VOICE_TRANSPARENT, outgoing
connections fail on connect() and returns -EOPNOTSUPP. Incoming
connections do not fail. However, they should only be allowed depending
on what was specified in Write_Voice_Settings command.

EOPNOTSUPP is choosen because connect() system call is failing after
selecting route but before any connection attempt.

iwl3945: better skb management in rx path

Steinar reported reallocations of skb->head with IPv6, leading to
a warning in skb_try_coalesce()

It turns out iwl3945 has several problems :

1) skb->truesize is underestimated.
   We really consume PAGE_SIZE bytes for a fragment,
   not the frame length.
2) 128 bytes of initial headroom is a bit low and forces reallocations.
3) We can avoid consuming a full page for small enough frames.

rt2x00: rt2800lib: fix default TX power values for RT3593

The TX power values in the EEPROM are using
a different format for the RT3593 chip. The
default TX power value uses bits 0..4 only.
Bits 5..8 contains value for fine grained
power control. Additionally, the lower and
upper limits of the TX power values are the
same for both bands.

Improve the rt2800_txpower_to_dev function,
in order to compute the correct default power
values for the RT3593 chip as well.

The change improves the readability and it makes
