From c5dfb000b90442e52f735bef4c2fc3f67783eaeb Mon Sep 17 00:00:00 2001 From: Hariprasad S Date: Fri, 11 Dec 2015 13:02:01 +0530 Subject: [PATCH] iw_cxgb4: Pass qid range to user space driver Enhances the t4_dev_status_page to pass the qid start and size attributes from iw_cxgb4 to libcxgb4. Bump the ABI Version to 3 -> To allow libcxgb4 to detect old drivers and revert to the old way of computing the qid ranges.
