2015-12-07	qed: fix handling of concurrent ramrods.	Tomer Tayar	1	-0/+2
	Concurrent non-blocking slowpath ramrods can be completed out-of-order on the completion chain. Recycling completed elements, while previously sent elements are still completion pending, can lead to overriding of active elements on the chain. Furthermore, sending pending slowpath ramrods currently lacks the update of the chain element physical pointer. This patch: * Ensures that ramrods are sent to the FW with consecutive echo values. * Handles out-of-order completions by freeing only first successive completed entries. * Updates the chain element physical pointer when copying a pending element into a free element for sending.

2015-10-28	qed: Add module with basic common support	Yuval Mintz	1	-0/+607
	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.
