BCMA is a Broadcom specific bus with devices AKA cores. All recent BCMA based SoCs have gigabit ethernet provided by the GBit MAC core. This patch adds driver for such a cores registering itself as a netdev. It has been tested on a BCM4706 and BCM4718 chipsets. In the kernel tree there is already b44 driver which has some common things with bgmac, however there are many differences that has led to the decision or writing a new driver: 1) GBit MAC cores appear on BCMA bus (not SSB as in case of b44) 2) There is 64bit DMA engine which differs from 32bit one 3) There is no CAM (Content Addressable Memory) in GBit MAC 4) We have 4 TX queues on GBit MAC devices (instead of 1) 5) Many registers have different addresses/values 6) RX header flags are also different The driver in it's state is functional how, however there is of course place for improvements: 1) Supporting more net_device_ops 2) SUpporting more ethtool_ops 3) Unaligned addressing in DMA 4) Writing separated PHY driver Signed-off-by:

We have skb_mac_header_was_set() helper to tell if mac_header was set on a skb. We would like the same for transport_header. __netif_receive_skb() doesn't reset the transport header if already set by GRO layer. Note that network stacks usually reset the transport header anyway, after pulling the network header, so this change only allows a followup patch to have more precise qdisc pkt_len computation for GSO packets at ingress side.

Paul Gortmaker says: ==================== I'd like to propose that we get rid of these old 8390 EISA drivers. Of the five deleted here, I wrote four -- and while that doesn't give me any authority for deletion above anyone else, it does at least allow me to comment on the absolute absence of anyone reaching out to the driver author for assistance in the last dozen years. Eventually we'll probably get rid of EISA bus support, since in x86, the hardware is close to 20 years old and already too resource constrained to be useful today. However there might still be a few DEC Alpha enthusiasts with old EISA machines kept alive, and so I expect we'll have to wait a bit longer to get unanimous agreement to proceed with the full EISA removal (although I'd love to be proven wrong on that). Most of the DEC Alpha machines shipped in a PCI configuration, and even the few that were EISA had DEC tulip based ethernet and no reason to be needing the inferior 8390 technology. So the interest here for any possible DEC enthusiasts with EISA boxes about these old 8390 drivers should be nil. These really were rare cards -- in fact the smc-ultra32 is the only one that I'd ever seen in person. Even back in the mid 90's when the drivers were written, I would guess that the user base was less than 10 people across all of them. The following patch was created with --irreversible-delete for ease of review (it skips showing the content of files that are deleted); however the complete patch can be pulled as per below. ==================== Signed-off-by:

In this patch the SR-IOV code is segregated from the main bulk of the bnx2x code. The CONFIG_BNX2X_SRIOV define is added to Broadcom's Kconfig, and allows the elision of the building of all the SR-IOV support code in the driver. The define is dependant on the kernel CONFIG_PCI_IOV configuration define. Signed-off-by:

The NS8390 chip was essentially the 1st widespread PC ethernet chip, starting its life on 8 bit ISA cards in the late 1980s. Even with better technologies available (bus mastering etc) the 8390 managed to get used on a few rare EISA cards in the early to mid 1990s. The EISA bus in the x86 world was largely confined to systems ranging from 486 to 586 (essentially 200MHz or lower, and less than 100MB RAM) -- i.e. machines unlikely to be still in service, and even less likely to be running a 3.9+ kernel. On top of that, only one of the five really ever was considered non-experimental; the smc-ultra32 was the one -- since it was largely just an EISA version of the popular smc-ultra ISA card. All the others had such a tiny user base that they simply never could be considered anything more than experimental. Signed-off-by:

splice() can handle pages of any order, but network code tries hard to split them in PAGE_SIZE units. Not quite successfully anyway, as __splice_segment() assumed poff < PAGE_SIZE. This is true for the skb->data part, not necessarily for the fragments. This patch removes this logic to give the pages as they are in the skb. Signed-off-by:

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:

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:
