* module_param: make bool parameters really bool (drivers & misc)Rusty Russell2012-01-12
| | | | | | | | | | | | module_param(bool) used to counter-intuitively take an int. In fddd5201 (mid-2009) we allowed bool or int/unsigned int using a messy trick. It's time to remove the int/unsigned int option. For this version it'll simply give a warning, but it'll break next kernel version.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This updates the network drivers so that they don't access the ethtool_cmd::speed field directly, but use ethtool_cmd_speed() instead. For most of the drivers, these changes are purely cosmetic and don't fix any problem, such as for those 1GbE/10GbE drivers that indirectly call their own ethtool get_settings()/mii_ethtool_gset(). The changes are meant to enforce code consistency and provide robustness with future larger throughputs, at the expense of a few CPU cycles for each ethtool operation.

* | RDMA/iwcm: Get rid of enum iw_cm_event_statusRoland Dreier2011-05-10
|/ | | | | | | | | | | | | | | | | | | | | | | | The IW_CM_EVENT_STATUS_xxx values were used in only a couple of places; cma.c uses -Exxx values instead, and so do the amso1100, cxgb3 and cxgb4 drivers -- only nes was using the enum values (with the mild consequence that all nes connection failures were treated as generic errors rather than reported as timeouts or rejections). We can fix this confusion by getting rid of enum iw_cm_event_status and using a plain int for struct iw_cm_event.status, and converting nes to use -Exxx as the other iWARP drivers do. This also gets rid of the warning drivers/infiniband/core/cma.c: In function 'cma_iw_handler': drivers/infiniband/core/cma.c:1333:3: warning: case value '4294967185' not in enumerated type 'enum iw_cm_event_status' drivers/infiniband/core/cma.c:1336:3: warning: case value '4294967186' not in enumerated type 'enum iw_cm_event_status' drivers/infiniband/core/cma.c:1332:3: warning: case value '4294967192' not in enumerated type 'enum iw_cm_event_status' Signed-off-by: Roland Dreier <roland@purestorage.com> Reviewed-by: Steve Wise <swise@opengridcomputing.com> Reviewed-by: Sean Hefty <sean.hefty@intel.com> Reviewed-by: Faisal Latif <faisal.latif@intel.com>

Plugging in a cable happens to result in series of interrupts changing driver's link state a number of times before finally staying at link up (e.g. link up, link down, link up, link down, ..., link up). To prevent sending series of redundant IB_EVENT_PORT_ACTIVE and IB_EVENT_PORT_ERR events, we use a timer to debounce them in nes_port_ibevent().
