IB/ipath: New sysfs entries to control 7220 features
IBA7220 includes many more configurable IB settings. Getting/setting these is now grouped into a pair of chip specific functions accessed via function pointers. Provide sysfs access to these settings. Signed-off-by: Michael Albaugh <michael.albaugh@qlogic.com> Signed-off-by: Roland Dreier <rolandd@cisco.com>
