Dan Carpenter	8c169c28f4	qlogic/qed: remove bogus NULL check ... We check if "p_hwfn" is NULL and then dereference it in the error handling code. I read the code and it isn't NULL so let's remove the check. Signed-off-by: Dan Carpenter <dan.carpenter@oracle.com> Acked-by: Yuval Mintz <Yuval.Mintz@qlogic.com> Signed-off-by: David S.

Yuval Mintz	cc875c2e4f	qed: Add link support ... Physical link is handled by the management Firmware. This patch lays the infrastructure for attention handling in the driver, as link change notifications arrive via async. attentions, as well the handling of such notifications. This patch also extends the API with the protocol drivers by adding registered callbacks which the protocol driver passes to qed in order to be notified of async. events originating from the FW/HW.

Yuval Mintz	fe56b9e6a8	qed: Add module with basic common support ... The Qlogic Everest Driver is the backend module for the QL4xxx ethernet products by Qlogic. This module serves two main purposes: 1. It's responsible to contain all the common code that will be shared between the various drivers that would be used with said line of products. Flows such as chip initialization and de-initialization fall under this category. 2. It would abstract the protocol-specific HW & FW components, allowing the protocol drivers to have a clean APIs which is detached in its slowpath configuration from the actual HSI. This adds a very basic module without any protocol-specific bits. I.e., this adds a basic implementation that almost entirely falls under the first category.
