The buffers for the TSO headers belong to a DMA coherent region which is allocated at ndo_open() time, and released at ndo_stop() time.

2014-06-02net: mv643xx_eth: Limit the TSO segments and adjust stop/wake thresholdsEzequiel Garcia
Currently small MSS values may require too many TSO descriptors for the default queue size. This commit prevents this situation by fixing the maximum supported TSO number of segments to 100 and by setting a minimum Tx queue size. The minimum Tx queue size is set so that at least 2 worst-case skb can be accommodated. In addition, the queue stop and wake thresholds values are adjusted accordingly. The queue is stopped when there's room for only 1 worst-case skb and waked when the number of descriptors is half that value.

2014-06-02net: cdc_ncm: allow tuning min_tx_pktBjørn Mork
The min_tx_pkt variable decides the cutoff point where the driver will stop padding out NTBs to maximum size. The padding is a tradeoff where we use some USB bus bandwidth to allow the device to receive fixed size buffers. Different devices will have different optimal settings, spanning from no padding at all to padding every NTB. There is no way to automatically figure out which setting is best for a specific device. The default value is a reasonable tradeoff, calculated based on the USB packet size and out NTB max size. This may have to be changed along with any tx_max changes.

2014-06-02net: cdc_ncm: export NCM Transfer Block (NTB) parametersBjørn Mork
The mandatory GetNtbParameters control request is an important part of the host <-> device protocol negotiation in CDC NCM (and CDC MBIM). It gives device limits which the host must obey when configuring the protocol aggregation variables. The driver will enforce this by rejecting attempts to set any of the tunable variables to a value which is not supported by the device. Exporting the parameter block helps userspace decide which values are allowed without resorting to trial and error. Signed-off-by: Bjørn Mork <bjorn@mork.no> Signed-off-by: David S. Miller <davem@davemloft.net>
2014-06-02net: cdc_ncm: drop ethtool coalesce supportBjørn Mork
The ethtool coalesce API is not applicable for this driver. Forcing it to fit the NCM aggregation redefined the API in a driver specific way, which is much worse than defining a clean new API. These ethtool coalesce functions have therefore been replaced by a new sysfs API. Signed-off-by: Bjørn Mork <bjorn@mork.no> Signed-off-by: David S. Miller <davem@davemloft.net>
2014-06-02net: cdc_ncm: use sysfs for rx/tx aggregation tuningBjørn Mork
Attach a driver specific sysfs group to the netdev, and use it for the rx/tx aggregation variables. The datagram aggregation defined by the CDC NCM specification is specific to this device class (including CDC MBIM). Using the ethtool interrupt coalesce API as an interface to the aggregation parameters redefined that API in a driver specific and confusing way. A sysfs group - makes it clear that this is a driver specific userspace API, and - allows us to export the real values instead of some translated version, and - lets us include more aggregation variables which were impossible to force into the ethtool API. Additionally, using sysfs allows tuning the driver on space constrained hosts where userspace tools like ethtool are undesired.

2014-06-02net: cdc_ncm: inform usbnet when rx buffers are reducedBjørn Mork
It doesn't matter whether the buffer size goes up or down. We have to keep usbnet and device syncronized to be able to split transfers at the correct boundaries. The spec allow skipping short packets when using max sized transfers. If we don't tell usbnet about our new expected rx buffer size, then it will merge and/or split NTBs. The driver does not support this, and the result will be lots of framing errors. Fix by always reallocating usbnet rx buffers when the rx_max value changes.

2014-06-02net: cdc_ncm: always reallocate tx_curr_skb when tx_max increasesBjørn Mork
We are calling usbnet_start_xmit() to flush any remaining data, depending on the side effect that tx_curr_skb is set to NULL, ensuring a new allocation using the updated tx_max. But this side effect will only happen if there were any cached data ready to transmit. If not, then an empty tx_curr_skb is still allocated using the old tx_max size.

For the mac80211 bits, Johannes says: "The remainder for -next right now is mostly fixes, and a handful of small new things like some CSA infrastructure, the regdb script mW/dBm conversion change and sending wiphy notifications." For the bluetooth bits, Gustavo says: "Some more patches for 3.16. There is nothing really special here, just a bunch of clean ups, fixes plus some small improvements. Please pull." For the nfc bits, Samuel says: "We have: - Felica (Type3) tags support for trf7970a - Type 4b tags support for port100 - st21nfca DTS typo fix - A few sparse warning fixes" For the atheros bits, Kalle says: "Ben added support for setting antenna configurations. Michal improved warm reset so that we would not need to fall back to cold reset that often, an issue where ath10k stripped protected flag while in monitor mode and made module initialisation asynchronous to fix the problems with firmware loading when the driver is linked to the kernel. Luca removed unused channel_switch_beacon callbacks both from ath9k and ath10k. Marek fixed Protected Management Frames (PMF) when using Action Frames. Also we had other small fixes everywhere in the driver." Along with that, there are a handful of updates to a variety of drivers. This includes updates to at76c50x-usb, ath9k, b43, brcmfmac, mwifiex, rsi, rtlwifi, and wil6210. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
2014-06-02ath10k: remove unnecessary htt rx corruption checkMichal Kazior
While fixing a bug reported by Avery I went ahead and added a warning suspecting there might be something more to the bug. This ended up with people reporting they see warnings during heavy traffic. This bought me some time and helped me understand the problem better - apparently fw/hw can report a chained msdus as follows: 1 msdu, 1 chained, 1 msdu (0 length). The patch removes the extra check but leaves the other change that fixed the original skb_push panic bug (msdu_chaining was overwritten in an unfortunate way which made the above example to be treated as non-chained case).

2014-06-02inetpeer: get rid of ip_id_countEric Dumazet
Ideally, we would need to generate IP ID using a per destination IP generator. linux kernels used inet_peer cache for this purpose, but this had a huge cost on servers disabling MTU discovery. 1) each inet_peer struct consumes 192 bytes 2) inetpeer cache uses a binary tree of inet_peer structs, with a nominal size of ~66000 elements under load. 3) lookups in this tree are hitting a lot of cache lines, as tree depth is about 20. 4) If server deals with many tcp flows, we have a high probability of not finding the inet_peer, allocating a fresh one, inserting it in the tree with same initial ip_id_count, (cf secure_ip_id()) 5) We garbage collect inet_peer aggressively. IP ID generation do not have to be 'perfect' Goal is trying to avoid duplicates in a short period of time, so that reassembly units have a chance to complete reassembly of fragments belonging to one message before receiving other fragments with a recycled ID. We simply use an array of generators, and a Jenkin hash using the dst IP as a key. ipv6_select_ident() is put back into net/ipv6/ip6_output.c where it belongs (it is only used from this file) secure_ip_id() and secure_ipv6_id() no longer are needed. Rename ip_select_ident_more() to ip_select_ident_segs() to avoid unnecessary decrement/increment of the number of segments. Signed-off-by: Eric Dumazet <edumazet@google.com> Signed-off-by: David S.

2014-06-02enic: Update driver to use __dev_uc/mc_sync/unsync callsAlexander Duyck
This change updates the enic driver to make use of __dev_uc_sync and __dev_mc_sync calls. Previously the driver was doing its own list management by storing the mc_addr and uc_addr list in a 32 address array. With this change the sync data is stored in the netdev_addr_list structures and instead we just track how many addresses we have written to the device. When we encounter 32 we stop and print a message as occurred previously with the old approach. Other than the core change the only other bit needed was to propagate the constant attribute with the MAC address as there were several spots where is twas only passed as a u8 * instead of a const u8 *. This patch is meant to maintain the original functionality without the use of the mc_addr and uc_addr arrays.
