* neigh: Convert garbage collection from softirq to workqueueEric Dumazet2009-08-022-48/+45
| | | | | | | | | | | | | | | | | | Current neigh_periodic_timer() function is fired by timer IRQ, and scans one hash bucket each round (very litle work in fact) As we are supposed to scan whole hash table in 15 seconds, this means neigh_periodic_timer() can be fired very often. (depending on the number of concurrent hash entries we stored in this table) Converting this to a workqueue permits scanning whole table, minimizing icache pollution, and firing this work every 15 seconds, independantly of hash table size. This 15 seconds delay is not a hard number, as work is a deferrable one. Signed-off-by: Eric Dumazet <eric.dumazet@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
* IPVS: use pr_err and friends instead of IP_VS_ERR and friendsHannes Eder2009-08-0221-152/+147
| | | | | | | | | | Since pr_err and friends are used instead of printk there is no point in keeping IP_VS_ERR and friends. Furthermore make use of '__func__' instead of hard coded function names.

* smsc95xx: remove EEPROM loaded checkSteve Glendinning2009-08-021-5/+0
| | | | | | | | | | | | The eeprom read & write commands currently check the E2P_CMD_LOADED_ bit is set before allowing any operations. This prevents any reading or writing unless a correctly programmed EEPROM is installed. This patch removes the check, so it is possible to program blank EEPROMS via ethtool.

* inet6: functions shadow global variableGerrit Renker2009-08-021-2/+2
| | | | | | | | | | | This renames away a variable clash: * ipv6_table[] is declared as a static global table; * ipv6_sysctl_net_init() uses ipv6_table to refer/destroy dynamic memory; * ipv6_sysctl_net_exit() also uses ipv6_table for the same purpose; * both the two last functions call kfree() on ipv6_table.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add debugfs file to enable/disable HT40(40MHz) channel support. By default, 40MHz is supported if AP can support the function. By echo "1" to "disable_ht40" file, iwlwifi driver will disable the 40MHz support and only allow 20MHz channel. Because the information exchange happen during association time, so enable/disable ht40 channel only can be performed when it is not associated with AP.

| * iwlwifi: fix up command sendingJohannes Berg2009-07-2714-142/+180
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The current command sending in iwlwifi is a bit of a mess: 1) there is a struct, iwl_cmd, that contains both driver and device data in a single packed structure -- this is very confusing 2) the on-stack data and the command metadata share a structure by embedding the latter in the former, which is also rather confusing because it leads to weird unions and similarly odd constructs 3) each txq always has enough space for 256 commands, even if only 32 end up being used This patch fixes these things: 1) rename iwl_cmd to iwl_device_cmd and keep track of command metadata and device command separately, in two arrays in each tx queue 2) remove the 'meta' member from iwl_host_cmd and only put in the required members 3) allocate the cmd/meta arrays separately instead of embedding them into the txq structure Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: Reinette Chatre <reinette.chatre@intel.com> Signed-off-by: John W.
