Could you please answer my below queries. Currently set_privacy() MGMT method is used to set the HCI_PRIVACY (LE controller) flag to enable host based privacy feature locally in kernel, when adapter is powered off. To enable controller based privacy, first we need to check whether LL supports the LL privacy feature and bit is set or not, if so . how and when controller based privacy to be set when adapter is powered off ? . Can set_privacy() MGMT method and HCI_PRIVACY flag be reused for controller based privacy also ? . OR should we introduce new flag like HCI_CTLR_PRIVACY and new MGMT method to set and differentiate controller and host based privacy code in kernel ? Thanks in advance & Best Regards, Paras Kumar ------=_NextPart_000_0239_01D0609F.638BD780 Content-Type: text/html; charset="us-ascii" Content-Transfer-Encoding: quoted-printable

Hi Marcel/ Hi = Johan,

 

I have some = questions related to LE Privacy 1.2 feature. Could you please answer my = below queries.

 

Currently = set_privacy() MGMT method is used to set the HCI_PRIVACY = (LE controller) flag to enable host based privacy feature = locally in kernel,

when adapter = is powered off. To enable controller based privacy, first we need to = check whether LL supports the LL privacy feature and bit is set = or not, if so

·    how and when = controller based privacy to be set when adapter is powered off = ?

·    Can se= t_privacy() MGMT method and HCI_PRIVACY flag be = reused for controller based privacy also = ?

·    OR should we = introduce new flag like HCI_CTLR_PRIVACY and new MGMT = method to set and differentiate controller and host based privacy = code in kernel ?

 

Thanks in = advance & 

Best = Regards,

Paras = Kumar
