[PATCH v4 07/11] qla2xxx: Add detection of secure device

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Quinn Tran <qutran@xxxxxxxxxxx>

Latest FC adapter from Marvell has the ability to encrypt
data in flight (EDIF) feature. This feature require an
application (ex: ipsec, etc) to act as an authenticator.

At this time, there is no FC switch scan service that
indicate a device is secure or non-secure.

In order to detect whether the remote port support secured
or not, driver must first do a PLOGI with the remote device.
On completion of the PLOGI, driver will query FW to see if
the device supports secure login. To do that, driver + FW
must advertise the security bit via PLOGI's service
parameter. The remote device shall respond with the same
service parameter bit on whether it supports it or not.
