This adds support for EATT bearer which was introduced in 5.2, they work as extra channels to have GATT traffic, at the moment it is completely transparent to application when they are in use since the allocation happens automatically.

Number of buffers available for fragments of TX buffers. Warning:
|
|
setting this to 0 means that the application must ensure that
|
|
queued TX buffers never need to be fragmented, i.e. that the
|
|
controller's buffer size is large enough. If this is not ensured,
|
|
and there are no dedicated fragment buffers, a deadlock may occur.
|
|
In most cases the default value of 2 is a safe bet.
