Subject: iw_cxgb4: Pass qid range to user space driver
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=c5dfb000b904;p=linux.git
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.
