This patch provides generic Large Receive Offload (LRO) functionality for IPv4/TCP traffic. LRO combines received tcp packets to a single larger tcp packet and passes them then to the network stack in order to increase performance (throughput). The interface supports two modes: Drivers can either pass SKBs or fragment lists to the LRO engine. Signed-off-by:

Veth stands for Virtual ETHernet. It is a simple tunnel driver that works at the link layer and looks like a pair of ethernet devices interconnected with each other. Mainly it allows to communicate between network namespaces but it can be used as is as well. The newlink callback is organized that way to make it easy to create the peer device in the separate namespace when we have them in kernel. This implementation uses another interface - the RTM_NRELINK message introduced by Patric. Bug fixes from Daniel Lezcano. Signed-off-by:

This routine gets the parsed rtnl attributes and creates a new link with generic info (IFLA_LINKINFO policy). Its intention is to help the drivers, that need to create several links at once (like VETH). This is nothing but a copy-paste-ed part of rtnl_newlink() function that is responsible for creation of new device. Signed-off-by:

Several devices have multiple independant RX queues per net device, and some have a single interrupt doorbell for several queues. In either case, it's easier to support layouts like that if the structure representing the poll is independant from the net device itself. The signature of the ->poll() call back goes from: int foo_poll(struct net_device *dev, int *budget) to int foo_poll(struct napi_struct *napi, int budget) The caller is returned the number of RX packets processed (or the number of "NAPI credits" consumed if you want to get abstract). The callee no longer messes around bumping dev->quota, *budget, etc. because that is all handled in the caller upon return. The napi_struct is to be embedded in the device driver private data structures. Furthermore, it is the driver's responsibility to disable all NAPI instances in it's ->stop() device close handler. Since the napi_struct is privatized into the driver's private data structures, only the driver knows how to get at all of the napi_struct instances it may have per-device. With lots of help and suggestions from Rusty Russell, Roland Dreier, Michael Chan, Jeff Garzik, and Jamal Hadi Salim. Bug fixes from Thomas Graf, Roland Dreier, Peter Zijlstra, Joseph Fannin, Scott Wood, Hans J. Koch, and Michael Chan. [ Ported to current tree and all drivers converted. Integrated Stephen's follow-on kerneldoc additions, and restored poll_list handling to the old style to fix mutual exclusion issues. -DaveM ] Signed-off-by:

zd1211rw and bcm43xx are interested in being notified when ERP IE conditions change, so that they can reprogram a register which affects how control frames are transmitted. This patch adds an interface similar to the one that can be found in softmac. Signed-off-by:

Similarly to CTS protection, whether short preambles are used for 802.11b transmissions should be a per-subif setting, not device global. For STAs, this patch makes short preamble handling automatic based on the ERP IE. For APs, hostapd still uses the prism ioctls, but the write ioctl has been restricted to AP-only subifs. ieee80211_txrx_data.short_preamble (an unused field) was removed. Unfortunately, some API changes were required for the following functions: - ieee80211_generic_frame_duration - ieee80211_rts_duration - ieee80211_ctstoself_duration - ieee80211_rts_get - ieee80211_ctstoself_get Affected drivers were updated accordingly.

mac80211 informs the driver what the short and long retry values are through set_retry_limit(), but when packets are being transmitted it did not inform the driver which of the 2 retry limits should actually be used. Instead it sends the actual value, but for drivers that can only set the retry limit and the register and in the descriptor need to indicate which of the limits should be used this is not really useful. This patch will add a IEEE80211_TXCTL_LONG_RETRY_LIMIT flag to the ieee80211_tx_control structure. By default the short retry limit should be used but if the flag is set the long retry should be used. This does not prevent the driver to ignore the request for "no retry" packets, but at least those will be send out with the short retry limit. But there is no perfect cure for this problem.. :( Signed-off-by:

My cheapy D-Link AP behaves strangely w.r.t reassociations. The following sequence of commands causes me to lose association and to be unable to regain it: ifconfig eth8 down ifconfig eth8 up iwconfig eth8 essid <x> This is because mac80211 tries to reassociate, rather than just associate. My AP replies with an association response (not a reassociation response...) denying the association with code 12: "Association denied due to reason outside the scope of this standard" mac80211 tries this reassociation another 4 times or so before finally giving up. I see 2 problems here: 1. bringing the interface down and up again should be resetting interface state i.e. after the interface is brought down, it should have no memory of if or where it was previously associated 2. after the first reassociation fails, mac80211 should fall back to standard association for the next attempt Signed-off-by: -

The sta_info code has some awkward locking which prevents some driver callbacks from being allowed to sleep. This patch makes the locking more focused so code that calls driver callbacks are allowed to sleep. It also converts sta_lock to a rwlock. Signed-off-by:

The ieee80211_rx_h_check handler really does two things, it's a lot easier to understand if it's split into ieee80211_rx_h_check and ieee80211_rx_h_load_key, and it may be possible in the future to optimise the key loading to not do it for each interface. Signed-off-by:

The recent mv_fill_sg() rewrite, to fix a data corruption problem related to IOMMU virtual merging, forgot to account for the potentially-increased size of the scatter/gather table after its run. Additionally, the DMA boundary is reduced from 0xffffffff to 0xffff to more closely match the needs of mv_fill_sg(). Signed-off-by:

This patch fixes a wrong ifdef in the board setup code, leading to the GPIO pin not being pulled high, and thus the USB switch not being powered at all. This finishes the rename of CONFIG_USB_OHCI to CONFIG_USB_OHCI_HCD, which started in 2005 (before 2.6.12-rc2), then probably because things were working anyway for most people got forgotten. [Ralf: Paolo's original patch didn't fix the module case, Florian's patch only fixed MTX1 etc. so this is a combined patch plus some cleanups.] Cc: Giuseppe Patanè <giuseppe.patane@tvblob.com> Cc: Ralf Baechle <ralf@linux-mips.org> Signed-off-by:

When building a custom keymap, after setting GENERATE_KEYMAP := 1 in drivers/char/Makefile, the kernel build fails like this: CC drivers/char/vt.o make[2]: *** No rule to make target `drivers/char/%.map', needed by `drivers/char/defkeymap.c'. Stop. make[1]: *** [drivers/char] Error 2 make: *** [drivers] Error 2 This was caused by commit af8b1287, which deleted a necessary colon from the Makefile rule that generates the keymap, since that rule contains both a target and a target-pattern.
