Currently, the size of skb allocated for NDISC is MAX_HEADER + LL_RESERVED_SPACE(dev) + packet length + dev->needed_tailroom, but only LL_RESERVED_SPACE(dev) bytes is "reserved" for headers. As a result, the skb looks like this (after construction of the message): head data tail end +--------------------------------------------------------------+ + | | | | +--------------------------------------------------------------+ |<-hlen---->|<---ipv6 packet------>|<--tlen-->|<--MAX_HEADER-->| =LL_ = dev RESERVED_ ->needed_ SPACE(dev) tailroom As the name implies, "MAX_HEADER" is used for headers, and should be "reserved" in prior to packet construction. Or, if some space is really required at the tail of ther skb, it should be explicitly documented. We have several option after construction of NDISC message: Option 1: head data tail end +---------------------------------------------+ + | | | +---------------------------------------------+ |<-hlen---->|<---ipv6 packet------>|<--tlen-->| =LL_ = dev RESERVED_ ->needed_ SPACE(dev) tailroom Option 2: head data tail end +--------------------------------------------------+ + | | | +--------------------------------------------------+ |<--MAX_HEADER-->|<---ipv6 packet------>|<--tlen-->| = dev ->needed_ tailroom Option 3: head data tail end +--------------------------------------------------------------+ + | | | | +--------------------------------------------------------------+ |<--MAX_HEADER-->|<-hlen---->|<---ipv6 packet------>|<--tlen-->| =LL_ = dev RESERVED_ ->needed_ SPACE(dev) tailroom Our tunnel drivers try expanding headroom and the space for tunnel encapsulation was not a mandatory space -- so we are not seeing bugs here --, but just for optimization for performance critial situations. Since NDISC messages are not performance critical unlike TCP, and as we know outgoing device, LL_RESERVED_SPACE(dev) should be just enough for the device in most (if not all) cases: LL_RESERVED_SPACE(dev) <= LL_MAX_HEADER <= MAX_HEADER Note that LL_RESERVED_SPACE(dev) is also enough for NDISC over SIT (e.g., ISATAP). So, I think Option 1 is just fine here. Signed-off-by:YOSHIFUJI Hideaki <yoshfuji@linux-ipv6.org> Acked-by:

MX6 and mx28 support enhanced DMA descriptor buff to support 1588 ptp. But MX25, MX3x, MX5x can't support enhanced DMA descriptor buff. Check fec type and choose correct DMA descriptor buff type. Remove static config CONFIG_FEC_PTP. ptp function will be auto detected. Signed-off-by:

Sparse complains that: drivers/net/ethernet/broadcom/tg3.c:5670:55: sparse: constant 0x7fffffffffffffff is so big it is long long (on x86/32 bit) so we suffix the constant with LL in the header file. Reported-by:

This patch enables USB dynamic autosuspend for LAN9500A. This saves very little power in itself, but it allows power saving in upstream hubs/hosts. The earlier devices in this family (LAN9500/9512/9514) do not support this feature. Signed-off-by:

The register read/write functions already log a warning if an access fails, so this patch removes the additional warnings logged by callers that don't add any more information. This patch makes the resulting driver smaller by not containing as many warning strings. Signed-off-by:

Jiri Pirko says: ==================== This is a V6 of a repost of my previous patchset: "[patch net-next v2 00/15] net: introduce upper device lists and remove dev->master" from Aug 14 The discussion around "[net-next] bonding: don't allow the master to become its slave" forced me to think about upper<->lower device connections. This patchset adds a possibility to record upper device linkage. All upper<->lower devices are converted to use this mechanism right after. That leads to dev->master removal because this info becomes redundant since "master links" have the same value. After all changes, there is no longer possible to do things as: "bond->someotherdevice->samebond" Also I think that drivers like cxgb3, qlcnic, qeth would benefit by this in future by being able to get more appropriate info about l3 addresses. v5->v6: - netdev_has_upper_dev() - added statement to comment that this is looking at the immediate upper devices only. - renamed "RTNL semaphore" -> "RTNL lock" in all comments - renamed __netdev_has_upper_dev() to __netdev_search_upper_dev() to emhasize the difference to netdev_has_upper_dev() v4->v5: - fixed missed typo in drivers/infiniband/hw/nes/nes_cm.c v3->v4: - comments in __netdev_upper_dev_link() squashed into one line - kfree_rcu used instead of call_rcu in netdev_upper_dev_unlink() v2->v3: - removed recursion in __netdev_has_upper_dev() - refreshed bits to be applicable on current net-next v1->v2: - s/unique/master/ better naming + stays closer to the past - fixed vlan err goto - original patch 15 (WARN_ON change) is squashed into the first patch ==================== Signed-off-by: -

This lists are supposed to serve for storing pointers to all upper devices. Eventually it will replace dev->master pointer which is used for bonding, bridge, team but it cannot be used for vlan, macvlan where there might be multiple upper present. In case the upper link is replacement for dev->master, it is marked with "master" flag. New upper device list resolves this limitation. Also, the information stored in lists is used for preventing looping setups like "bond->somethingelse->samebond" Signed-off-by:

Flash template provides instructions to stop, restart and initalize the firmware. These instructions are abstracted as a series of read, write and poll operations on hardware registers. Register information and operation specifics are not exposed to the driver. Driver reads the template from flash and executes the instructions located at pre-defined offsets. Template based firmware reset recovery and initialization mechanism minimize driver changes as firmware evolves. Signed-off-by:
