comment "Bluetooth HCI Driver Options"
# Controller support is an HCI driver in itself, so these HCI driver
# options are only applicable if controller support hasn't been enabled.

Bluetooth three-wire (H:5) UART driver. Implementation of HCI
Three-Wire UART Transport Layer.

This is intended for unit tests where no internal driver
should be selected.

help
Enable this to have the host stack manage incoming ACL data
and HCI event buffers. This makes sense for all HCI drivers
that talk to a controller running on a different CPU.
If the controller resides in the same address space it may
make sense to have the lower layers manage these buffers, in
which case this option can be left disabled.
