* mac80211: clean up beacon interval settingsJohannes Berg2009-05-06
| | | | | | | | | | | | | | | | | | | | We currently have two beacon interval configuration knobs: hw.conf.beacon_int and vif.bss_info.beacon_int. This is rather confusing, even though the former is used when we beacon ourselves and the latter when we are associated to an AP. This just deprecates the hw.conf.beacon_int setting in favour of always using vif.bss_info.beacon_int. Since it touches all the beaconing IBSS code anyway, we can also add support for the cfg80211 IBSS beacon interval configuration easily. NOTE: The hw.conf.beacon_int setting is retained for now due to drivers still using it -- I couldn't untangle all drivers, some are updated in this patch.

* net: remove driver_data direct access of struct device from more driversGreg Kroah-Hartman2009-05-05
| | | | | | | | | | | In the near future, the driver core is going to not allow direct access to the driver_data pointer in struct device. Instead, the functions dev_get_drvdata() and dev_set_drvdata() should be used. These functions have been around since the beginning, so are backwards compatible with all older kernel versions.

| | | | | | | | | | | | | | | | | | | | | | | | LAN9512 and LAN9514 are USB hubs with an integrated 10/100 ethernet controller. Logically this looks like an ethernet controller (similar to LAN9500) permanently attached to one of the hub's downstream ports. This patch adds the usb device id of the new ethernet controller to the smsc95xx driver. This id is the same in both new devices.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When netconsole is loaded and a network interface fades away (e.g. on rmmod $interface_driver_module) the rmmod remains stuck and some locks are taken that prevent any additional module loading/unloading as well as interface up/down changes. In addition kernel logs (and console) get flooded at 10s interval with [ 122.464065] unregister_netdevice: waiting for eth0 to become free. Usage count = 1 [ 132.704059] unregister_netdevice: waiting for eth0 to become free.

| * mv643xx_eth: 64bit mib counter read fixLennert Buytenhek2009-04-29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On several mv643xx_eth hardware versions, the two 64bit mib counters for 'good octets received' and 'good octets sent' are actually 32bit counters, and reading from the upper half of the register has the same effect as reading from the lower half of the register: an atomic read-and-clear of the entire 32bit counter value. This can under heavy traffic occasionally lead to small numbers being added to the upper half of the 64bit mib counter even though no 32bit wrap has occured. Since we poll the mib counters at least every 30 seconds anyway, we might as well just skip the reads of the upper halves of the hardware counters without breaking the stats, which this patch does.

| * mv643xx_eth: OOM handling fixesLennert Buytenhek2009-04-29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, when OOM occurs during rx ring refill, mv643xx_eth will get into an infinite loop, due to the refill function setting the OOM bit but not clearing the 'rx refill needed' bit for this queue, while the calling function (the NAPI poll handler) will call the refill function in a loop until the 'rx refill needed' bit goes off, without checking the OOM bit. This patch fixes this by checking the OOM bit in the NAPI poll handler before attempting to do rx refill. This means that once OOM occurs, we won't try to do any memory allocations again until the next invocation of the poll handler. While we're at it, change the OOM flag to be a single bit instead of one bit per receive queue since OOM is a system state rather than a per-queue state, and cancel the OOM timer on entry to the NAPI poll handler if it's running to prevent it from firing when we've already come out of OOM.

| * | e100: do not go D3 in shutdown unless system is powering offThadeu Lima de Souza Cascardo2009-04-29
| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | After experimenting with kexec with the last merges after 2.6.29, I've had some problems when probing e100. It would not read the eeprom. After some bisects, I realized this has been like that since forever (at least 2.6.18). The problem is that shutdown is doing the same thing that suspend does and puts the device in D3 state. I couldn't find a way to get the device back to a sane state in the probe function. So, based on some similar patches from Rafael J. Wysocki for e1000, e1000e, and ixgbe, I wrote this one for e100.

This was needed for pre-release hardware, and was not removed from the driver. Also, we need to clear the WUS (wake up status) after we resume. Otherwise we can't wake for the same event again since it's still asserted in the hardware. Plus, the multicast lists were being written improperly, causing multicast WoL to fail.
