As network adapters supporting PTP are becoming more common, machines with many NICs suddenly have many PHCs, too. The current limit of eight /dev/ptp* char devices (and thus, 8 network interfaces with PHC) is insufficient. Let the ptp driver allocate the char devices dynamically. Tested with 28 PHCs, removing and re-adding some of them. Thanks to Ben Hutchings for advice leading to simpler and cleaner patch.

I noticed that TSQ (TCP Small queues) was less effective when TSO is turned off, and GSO is on. If BQL is not enabled, TSQ has then no effect. It turns out the GSO engine frees the original gso_skb at the time the fragments are generated and queued to the NIC. We should instead call the tcp_wfree() destructor for the last fragment, to keep the flow control as intended in TSQ. This effectively limits the number of queued packets on qdisc + NIC layers.

After commit 2b8b328b (vhost_net: handle polling errors when setting backend), we in fact track the polling state through poll->wqh, so there's no need to duplicate the work with an extra vhost_net_polling_state. So this patch removes this and make the code simpler. This patch also removes the all tx starting/stopping code in tx path according to Michael's suggestion. Netperf test shows almost the same result in stream test, but gets improvements on TCP_RR tests (both zerocopy or copy) especially on low load cases.

由 Hadar Hen Zion 提交于
The different steering modes are global to the device, with DMFS being introduced after SRIOV was merged. Hence, SRIOV guests running legacy / older Linux kernels or non-Linux drivers may provide B0 steering directives when the hypervisor is using DMFS and fail. Under B0 only L2 steering rules are allowed, hence B0 is a subset of DMFS. Use this fact to enable such legacy guests to run by modifying the SRIOV B0 steering wrapper to translate guest B0 directives to DMFS ones when the device uses DMFS. The translated B0 rule has to be kept in the resource tracker as a B0 object to allow for lookup in case of detach.

The link change is detected via the interrupt pipe, and bulk pipes are responsible for transfering packets, so it is reasonable to stop bulk transfer after link is reported as off. Two adavantages may be obtained with stopping bulk transfer after link becomes off: - USB bus bandwidth is saved(USB bus is shared bus except for USB3.0), for example, lots of 'IN' token packets and 'NYET' handshake packets is transfered on 2.0 bus. - probabaly power might be saved for usb host controller since cancelling bulk transfer may disable the asynchronous schedule of host controller. With this patch, when link becomes off, about ~10% performance boost can be found on bulk transfer of anther usb device which is attached to same bus with the usbnet device, see below test on next-20130410: - read from usb mass storage(Sandisk Extreme USB 3.0) on pandaboard with below command after unplugging ethernet cable: dd if=/dev/sda iflag=direct of=/dev/null bs=1M count=800 - without the patch 1, 838860800 bytes (839 MB) copied, 36.2216 s, 23.2 MB/s 2, 838860800 bytes (839 MB) copied, 35.8368 s, 23.4 MB/s 3, 838860800 bytes (839 MB) copied, 35.823 s, 23.4 MB/s 4, 838860800 bytes (839 MB) copied, 35.937 s, 23.3 MB/s 5, 838860800 bytes (839 MB) copied, 35.7365 s, 23.5 MB/s average: 23.6MB/s - with the patch 1, 838860800 bytes (839 MB) copied, 32.3817 s, 25.9 MB/s 2, 838860800 bytes (839 MB) copied, 31.7389 s, 26.4 MB/s 3, 838860800 bytes (839 MB) copied, 32.438 s, 25.9 MB/s 4, 838860800 bytes (839 MB) copied, 32.5492 s, 25.8 MB/s 5, 838860800 bytes (839 MB) copied, 31.6178 s, 26.5 MB/s average: 26.1MB/s Signed-off-by: NMing Lei <ming.lei@canonical.com> Signed-off-by: NDavid S.

John W. Linville says: ==================== Please accept this pull request for the 3.10 stream... Regarding the mac80211 bits, Johannes says: "Here I have a bunch of minstrel fixes from Felix, per-interface multicast filtering from Alex, set_tim debouncing from Ilan, per-interface debugfs cleanups from Stanislaw, an error return fix from Wei and a number of small improvements and fixes that I made myself." And for the iwlwifi bits, Johannes says: "Andrei changed an instance of kmalloc+memdup to kmemdup, Stanislaw removed the now unused 5ghz_disable module parameter. I also have a number of fixes from Ilan, Emmanuel and myself, Emmanuel also continued working on Bluetooth coexistence." For the sizeable batch of Bluetooth bits, Gustavo says: "This is our first batch of patches for 3.10. The biggest changes of this pull request are from Johan Hedberg, he implemented a HCI request framework to make life easier when we have to send many HCI commands and a block and wait for all of the to finish, we were able to fix a few issues in stack with the introduction of this framework. Other than that Dean Jenkins did a good work cleaning the RFCOMM code, the refcnt infrastructure was removed and now we use NULL pointer checks to know when a object was freed or not. That code was buggy and now it looks a way better. The rest of changes are clean ups, fixes and small improvements all over the Bluetooth subsystem." Regarding the wl12xx bits, Luca says: "Some patches intended for 3.10. Mostly bug fixes and other small improvements." On top of that, there are updates to brcmfmac, brcmsmac, b43, ssb and bcma, as well as mwifiex, rt2x00, and ath9k and a few others. The most notable bit is the addition of a new driver in the rtlwifi family. Please let me know if there are problems! ==================== Signed-off-by: NDavid S. Miller <davem@davemloft.net>
