由 Arnd Bergmann 提交于
The documentation for the USB ethernet devices suggests that only some devices are supposed to use usb0 as the network interface name instead of eth0. The logic used there, and documented in Kconfig for CDC is that eth0 will be used when the mac address is a globally assigned one, but usb0 is used for the locally managed range that is typically used on point-to-point links. Unfortunately, this has caused a lot of pain on the smsc95xx device that is used on the popular pandaboard without an EEPROM to store the MAC address, which causes the driver to call random_ether_address(). Obviously, there should be a proper MAC addressed assigned to the device, and discussions are ongoing about how to solve this, but this patch at least makes sure that the default interface naming gets a little saner and matches what the user can expect based on the documentation, including for new devices. The approach taken here is to flag whether a device might be a point-to-point link with the new FLAG_POINTTOPOINT setting in the usbnet driver_info. A driver can set both FLAG_POINTTOPOINT and FLAG_ETHER if it is not sure (e.g. cdc_ether), or just one of the two. The usbnet framework only looks at the MAC address for device naming if both flags are set, otherwise it trusts the flag.

This adds a driver for the CDC Ethernet part of this modem. The device's ID is blacklisted in cdc_ether.c and is white-listed in this new driver because of the quirks needed to make it useful. The modem's firmware exposes a CDC ACM port for modem control and a CDC Ethernet port for network data. The descriptors look fine but both ports actually are some sort of multiplexers requiring non- standard headers added/removed from every packet or they get ignored. All information is based on a usb traffic log from a Windows machine. On the Verizon 4G network I've seen speeds up to 1.1MB/s so far with this driver, a speed-o-meter site reports 16.2Mbps/10.5Mbps. Userspace scripts are required to talk to the CDC ACM port. Signed-off-by: NAndrzej Zaborowski <balrogg@gmail.com> Signed-off-by: NDavid S. Miller <davem@davemloft.net>

These macros are too similar to the dev_<level> equivalents but take a usbnet * argument. Convert them to the recently introduced netdev_<level> macros and remove the old macros. The old macros had "\n" appended to the format string. Add the "\n" to the converted uses. Some existing uses of the dev<foo> macros in cdc_eem.c probably mistakenly had trailing "\n".

Usbnet framework assumes USB hardware doesn't handle zero length packets, but SMSC LAN95xx requires these to be sent for correct operation. This patch fixes an easily reproducible tx lockup when sending a frame that results in exactly 512 bytes in a USB transmission (e.g. a UDP frame with 458 data bytes, due to IP headers and our USB headers). It adds an extra flag to usbnet for the hardware driver to indicate that it can handle and requires the zero length packets. This patch should not affect other usbnet users, please also consider for -stable. Signed-off-by: NSteve Glendinning <steve.glendinning@smsc.com> Signed-off-by: NDavid S. Miller <davem@davemloft.net>

It is preferable to group drivers by usage (net, scsi, ATA, ...) than by bus. When reviewing drivers, the [PCI|USB|PCMCIA|...] maintainer is probably less qualified on networking issues than a networking maintainer. Also, from a practical standpoint, chips often appear on multiple buses, which is why we do not put drivers into drivers/pci/net.

These are now implemented using mii functions when a low-level driver supports mdio_read/mdio_write and does not override the usbnet ethtool commands with its own.

This patch moves the ASIX AX8817x driver into its own file, just using the "usbnet" infrastructure as a utility library. - As with "cdc_subset" this involved minor Kconfig/kbuild tweaks, moving code from one file to another, and exporting a few functions. - This includes updates from Jamie Painter to add (and use) a new hook to handle the different maximum transfer sizes for rx and tx sides. - Also from Jamie, some bugfixes: * MDIO byteorder (to address some PPC media negotiation problems); * Force alignment at key spots when using ax88772 framing (on some embedded hardware, the network stack will break otherwise); * Address some link reset problems. It also makes this driver use the standard (5 seconds vs half second) control timeouts used elsewhere in USB; and wraps a few lines before the 80th column (which previously needed it).

This one handles only the very simplest hardware, which can be handled almost entirely by the "usbnet" core. - Move device-specific bits into new "cdc_subset.c" driver, shrinking "usbnet" by a bunch; - Export the functions needed to support this minidriver (with EXPORT_SYMBOL_GPL); - Update Kconfig and kbuild accordingly.

This starts to prepare the core of "usbnet" to know less about various framing protocols that map Ethernet packets onto USB, so "minidrivers" can be modules that just plug into the core. - Remove some framing-specific code that cluttered the core: * net->hard_header_len records how much space to preallocate; now drivers that add their own framing (Net1080, GeneLink, Zaurus, and RNDIS) will have smoother TX paths. Even for the drivers (Zaurus, Net1080) that need trailers. * defines new dev->hard_mtu, using this "hardware" limit to check changes to the link's settable "software" mtu. * now net->hard_header_len and dev->hard_mtu are set up in the driver bind() routines, if needed. - Transaction ID is no longer specific to the Net1080 framing; RNDIS needs one too. - Creates a new "usbnet.h" header with declarations that are shared between the core and what will be separate modules. - Plus a couple other minor tweaks, like recognizing -ESHUTDOWN means the keventd work should just shut itself down asap. The core code is only about 1/3 of this large file. Splitting out the minidrivers into separate modules (e.g. ones for ASIX adapters, Zaurii and similar, CDC Ethernet, etc), in later patches, will improve maintainability and shrink typical runtime footprints.
