* ath5k: better beacon timer calculationBruno Randolf2008-01-281-17/+92
| | | | | | | | | | | | | | | update ath5k_beacon_update_timers() for better beacon timer calculation in a variety of situations. most important is the possibility to call it with the timestamp of a received beacon, when we detected that a HW merge has happened and we need to reconfigure the beacon timers based on that. we call this from the mac80211 callback reset_tsf now instead of beacon_update, and there will be more use of it in the next patch. drivers/net/wireless/ath5k/base.c: Changes-licensed-under: 3-Clause-BSD Signed-off-by: Bruno Randolf <bruno@thinktube.com> Signed-off-by: John W.

| | | | | | | | | | | | | the beacon interval is passed by mac80211 in TU already, so we can directly use it without conversion. also update the comments about TU (1 TU is defined by 802.11 as 1024usec). drivers/net/wireless/ath5k/ath5k.h: Changes-licensed-under: ISC drivers/net/wireless/ath5k/base.c: Changes-licensed-under: 3-Clause-BSD drivers/net/wireless/ath5k/base.h: Changes-licensed-under: 3-Clause-BSD Signed-off-by: Bruno Randolf <bruno@thinktube.com> Signed-off-by: John W.

* b43: Fix MAC control and microcode initMichael Buesch2008-01-281-13/+48
| | | | | | | | | | | | | | | | | | | | This zeros out all microcode related memory before loading the microcode. This also fixes initialization of the MAC control register. The _only_ place where we overwrite the contents of the MAC control register is at the beginning of b43_chip_init(). All other places must do read() -> mask/set -> write() to not overwrite existing bits. This also adds a longer delay for waiting for the microcode to initialize itself. It seems that the current timeout is sufficient on all available devices, but there's no real reason why we shouldn't wait for up to one second. Slow embedded devices might exist. Better safe than sorry. Signed-off-by: Michael Buesch <mb@bu3sch.de> Signed-off-by: John W. Linville <linville@tuxdriver.com>

| | | | | | | | | | | Commit c7a51bda ("mac80211: restructure __ieee80211_rx") extracted __ieee80211_rx_handle_packet out of __ieee80211_rx and hence changed the locking rules for __ieee80211_rx_handle_packet(), it is now invoked under RCU lock.

* [DST]: shrinks sizeof(struct rtable) by 64 bytes on x86_64Eric Dumazet2008-01-282-11/+12
| | | | | | | | | | | | | | | | | | | On x86_64, sizeof(struct rtable) is 0x148, which is rounded up to 0x180 bytes by SLAB allocator. We can reduce this to exactly 0x140 bytes, without alignment overhead, and store 12 struct rtable per PAGE instead of 10. rate_tokens is currently defined as an "unsigned long", while its content should not exceed 6*HZ. It can safely be converted to an unsigned int. Moving tclassid right after rate_tokens to fill the 4 bytes hole permits to save 8 bytes on 'struct dst_entry', which finally permits to save 8 bytes on 'struct rtable' Signed-off-by: Eric Dumazet <dada1@cosmosbay.com> Signed-off-by: David S.

* [NETNS][FRAGS]: Make the pernet subsystem for fragments.Pavel Emelyanov2008-01-284-2/+33
| | | | | | | | | | On namespace start we mainly prepare the ctl variables. When the namespace is stopped we have to kill all the fragments that point to this namespace.

* [NETNS][FRAGS]: Make the LRU list per namespace.Pavel Emelyanov2008-01-285-8/+8
| | | | | | | | | | | | | The inet_frags.lru_list is used for evicting only, so we have to make it per-namespace, to evict only those fragments, who's namespace exceeded its high threshold, but not the whole hash. Besides, this helps to avoid long loops in evictor. The spinlock is not per-namespace because it protects the hash table as well, which is global.

* [NETNS][FRAGS]: Isolate the secret interval from namespaces.Pavel Emelyanov2008-01-286-23/+8
| | | | | | | | | | | | Since we have one hashtable to lookup the fragment, having different secret_interval-s for hash rebuild doesn't make sense, so move this one to inet_frags. The inet_frags_ctl becomes empty after this, so remove it. The appropriate ctl table is kept read-only in namespaces. Signed-off-by: Pavel Emelyanov <xemul@openvz.org> Signed-off-by: David S.

* [NETNS][FRAGS]: Duplicate sysctl tables for new namespaces.Pavel Emelyanov2008-01-284-6/+79

* [NETNS][FRAGS]: Make the nqueues counter per-namespace.Pavel Emelyanov2008-01-289-12/+24

* [NETNS][FRAGS]: Make the inet_frag_queue lookup work in namespaces.Pavel Emelyanov2008-01-287-21/+38
| | | | | | | | | | | | | | | | Since fragment management code is consolidated, we cannot have the pointer from inet_frag_queue to struct net, since we must know what king of fragment this is. So, I introduce the netns_frags structure. This one is currently empty, but will be eventually filled with per-namespace attributes. Each inet_frag_queue is tagged with this one. The conntrack_reasm is not "netns-izated", so it has one static netns_frags instance to keep working in init namespace. Signed-off-by: Pavel Emelyanov <xemul@openvz.org> Signed-off-by: David S. Miller <davem@davemloft.net>
* [NETNS][FRAGS]: Move ctl tables around.Pavel Emelyanov2008-01-2810-128/+169
| | | | | | | | | | | | | | | | This is a preparation for sysctl netns-ization. Move the ctl tables to the files, where the tuning variables reside. Plus make the helpers to register the tables. This will simplify the later patches and will keep similar things closer to each other. ipv4, ipv6 and conntrack_reasm are patched differently, but the result is all the tables are in appropriate files.

* igb: PCI-Express 82575 Gigabit Ethernet driverAuke Kok2008-01-2817-0/+13638
| | | | | | | | | | | | | | | | | | | | | | | | | | | We are pleased to announce a new Gigabit Ethernet product and its driver to the linux community. This product is the Intel(R) 82575 Gigabit Ethernet adapter family. Physical adapters will be available to the public soon. These adapters come in 2- and 4-port versions (copper PHY) currently. Other variants will be available later. The 82575 chipset supports significantly different features that warrant a new driver. The descriptor format is (just like the ixgbe driver) different. The device can use multiple MSI-X vectors and multiple queues for both send and receive. This allows us to optimize some of the driver code specifically as well compared to the e1000-supported devices. This version of the igb driver no lnger uses fake netdevices and incorporates napi_struct members for each ring to do the multi- queue polling. multi-queue is enabled by default and the driver supports NAPI mode only. All the namespace collisions should be gone in this version too. The register macro's have been condensed to improve readability.
