Subject: Re: [PATCH v3 6/9] Bluetooth: Add 'dst_type' field to struct hci_conn
Date: Mon, 30 May 2011 19:30:27 -0300 [thread overview]
Message-ID: <20110530223026.GK2556@joana> (raw)

Hi Andre,
* Andre Guedes <andre.guedes@openbossa.org> [2011-05-26 16:23:54 -0300]:
> This patch adds a new field (dst_type) to the struct hci_conn which
> holds the type of the destination address (bdaddr_t dst). This
> approach is needed in order to use the struct hci_conn as an
> abstraction of LE connections in HCI Layer.
>
> This patch also adds a new parameter to hci_conn_add() since now the
> address type must be considered to create LE struct hci_conn objects.
> For non-LE that parameter is ignored.

just set conn->dst_type here might be a better idea. Then we don't need to
modify hci_conn_add() parameters.
