2010-08-17ethtool: Provide a default implementation of ethtool_ops::get_drvinfoBen Hutchings
The driver name and bus address for a net_device can normally be found through the driver model now. Instead of requiring drivers to provide this information redundantly through the ethtool_ops::get_drvinfo operation, use the driver model to do so if the driver does not define the operation. Since ETHTOOL_GDRVINFO no longer requires the driver to implement any operations, do not require net_device::ethtool_ops to be set either. Remove implementations of get_drvinfo and ethtool_ops that provide only this information. Signed-off-by: Ben Hutchings <bhutchings@solarflare.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2010-08-16mac80211: AMPDU rx reorder timeout timerChristian Lamparter
This patch introduces a new timer, which will release queued-up MPDUs from the reorder buffer, whenever they've waited for more than HT_RX_REORDER_BUF_TIMEOUT (which is at around 100 ms). The advantage of having a dedicated timer, instead of relying on a constant stream of freshly arriving aMPDUs to release the old ones, is particularly observable when even a small fraction of MPDUs are forever lost at low network speeds. Previously under these circumstances frames would become stuck in the reorder buffer and the network stack of both HT peers throttled back, instead of revving up and gunning the pipes.

2010-08-16mac80211: support use of NAPI for bottom-half processingJohn W. Linville
This patch implement basic infrastructure to support use of NAPI by mac80211-based hardware drivers. Because mac80211 devices can support multiple netdevs, a dummy netdev is used for interfacing with the NAPI code in the core of the network stack. That structure is hidden from the hardware drivers, but the actual napi_struct is exposed in the ieee80211_hw structure so that the poll routines in drivers can retrieve that structure. Hardware drivers can also specify their own weight value for NAPI polling. Signed-off-by: John W. Linville <linville@tuxdriver.com>

2010-08-11DNS: If the DNS server returns an error, allow that to be cached [ver #2]Wang Lei
If the DNS server returns an error, allow that to be cached in the DNS resolver key in lieu of a value. Userspace passes the desired error number as an option in the payload: "#dnserror=<number>" Userspace must map h_errno from the name resolution routines to an appropriate Linux error before passing it up. Something like the following mapping is recommended: [HOST_NOT_FOUND] = ENODATA, [TRY_AGAIN] = EAGAIN, [NO_RECOVERY] = ECONNREFUSED, [NO_DATA] = ENODATA, in lieu of Linux errors specifically for representing name service errors. The filesystem must map these errors appropropriately before passing them to userspace. AFS is made to map ENODATA and EAGAIN to EDESTADDRREQ for the return to userspace; ECONNREFUSED is allowed to stand as is. The error can be seen in /proc/keys as a negative number after the description of the key. Compare, for example, the following key entries: 2f97238c I--Q-- 1 53s 3f010000 0 0 dns_resol afsdb:grand.centrall.org: -61 338bfbbe I--Q-- 1 59m 3f010000 0 0 dns_resol afsdb:grand.central.org: 37 If the error option is supplied in the payload, the main part of the payload is discarded. The key should have an expiry time set by userspace.

2010-08-11param: use ops in struct kernel_param, rather than get and set fns directlyRusty Russell
This is more kernel-ish, saves some space, and also allows us to expand the ops without breaking all the callers who are happy for the new members to be NULL. The few places which defined their own param types are changed to the new scheme (more which crept in recently fixed in following patches). Since we're touching them anyway, we change get() and set() to take a const struct kernel_param (which they really are). This causes some harmless warnings until we fix them (in following patches). To reduce churn, module_param_call creates the ops struct so the callers don't have to change (and casts the functions to reduce warnings). The modern version which takes an ops struct is called module_param_cb.
