* net: add 802.1ad / 802.1ah / QinQ ethertypesDavid Lamparter2011-07-17
| | | | | | | | | | | | define ETH_P_8021AD to 88a8 (assigned by IEEE) and add ETH_P_QINQ{1,2,3} for the pre-standard 9{1,2,3}00 types. all of them use 802.1q frame format, with 1 bit used differently in some cases. also define ETH_P_8021AH to 88e7 (assigned by IEEE). this is Mac-in-Mac and uses a different, 16-byte header.

* net: add mac_pton() for parsing MAC addressAlexey Dobriyan2011-05-09
| | | | | | | | | | | | | | | | | | | | | | mac_pton() parses MAC address in form XX:XX:XX:XX:XX:XX and only in that form. mac_pton() doesn't dirty result until it's sure string representation is valid. mac_pton() doesn't care about characters _after_ last octet, it's up to caller to deal with it. mac_pton() diverges from 0/-E return value convention. Target usage: if (!mac_pton(str, whatever->mac)) return -EINVAL; /* ->mac being u8 [ETH_ALEN] is filled at this point. */ /* optionally check str[3 * ETH_ALEN - 1] for termination */ Use mac_pton() in pktgen and netconsole for start.

* gre: Add Transparent Ethernet BridgingHerbert Xu2008-10-09
| | | | | | | | | | | | | | | This patch adds support for Ethernet over GRE encapsulation. This is exposed to user-space with a new link type of "gretap" instead of "gre". It will create an ARPHRD_ETHER device in lieu of the usual ARPHRD_IPGRE. Note that to preserver backwards compatibility all Transparent Ethernet Bridging packets are passed to an ARPHRD_IPGRE tunnel if its key matches and there is no ARPHRD_ETHER device whose key matches more closely.

* dsa: add support for Trailer tagging formatLennert Buytenhek2008-10-08
| | | | | | | | | | | | This adds support for the Trailer switch tagging format.

* dsa: add support for original DSA tagging formatLennert Buytenhek2008-10-08
| | | | | | | | | | | | | | | | | | | | | | | | | Most of the DSA switches currently in the field do not support the Ethertype DSA tagging format that one of the previous patches added support for, but only the original DSA tagging format. The original DSA tagging format carries the same information as the Ethertype DSA tagging format, but with the difference that it does not have an ethertype field. In other words, when receiving a packet that is tagged with an original DSA tag, there is no way of telling in eth_type_trans() that this packet is in fact a DSA-tagged packet. This patch adds a hook into eth_type_trans() which is only compiled in if support for a switch chip that doesn't support Ethertype DSA is selected, and which checks whether there is a DSA switch driver instance attached to this network device which uses the old tag format. If so, it sets the protocol field to ETH_P_DSA without looking at the packet, so that the packet ends up in the right place.

* net: Distributed Switch Architecture protocol supportLennert Buytenhek2008-10-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Distributed Switch Architecture is a protocol for managing hardware switch chips. It consists of a set of MII management registers and commands to configure the switch, and an ethernet header format to signal which of the ports of the switch a packet was received from or is intended to be sent to. The switches that this driver supports are typically embedded in access points and routers, and a typical setup with a DSA switch looks something like this: +-----------+ +-----------+ | | RGMII | | | +-------+ +------ 1000baseT MDI ("WAN") | | | 6-port +------ 1000baseT MDI ("LAN1") | CPU | | ethernet +------ 1000baseT MDI ("LAN2") | |MIImgmt| switch +------ 1000baseT MDI ("LAN3") | +-------+ w/5 PHYs +------ 1000baseT MDI ("LAN4") | | | | +-----------+ +-----------+ The switch driver presents each port on the switch as a separate network interface to Linux, polls the switch to maintain software link state of those ports, forwards MII management interface accesses to those network interfaces (e.g. as done by ethtool) to the switch, and exposes the switch's hardware statistics counters via the appropriate Linux kernel interfaces. This initial patch supports the MII management interface register layout of the Marvell 88E6123, 88E6161 and 88E6165 switch chips, and supports the "Ethertype DSA" packet tagging format. (There is no officially registered ethertype for the Ethertype DSA packet format, so we just grab a random one. The ethertype to use is programmed into the switch, and the switch driver uses the value of ETH_P_EDSA for this, so this define can be changed at any time in the future if the one we chose is allocated to another protocol or if Ethertype DSA gets its own officially registered ethertype, and everything will continue to work.)

* [ETH]: Combine format_addr() with print_mac().Michael Chan2008-01-28
| | | | | | | | | | | | | | | | | | | print_mac() used many most net drivers and format_addr() used by net-sysfs.c are very similar and they can be intergrated. format_addr() is also identically redefined in the qla4xxx iscsi driver. Export a new function sysfs_format_mac() to be used by net-sysfs, qla4xxx and others in the future. Both print_mac() and sysfs_format_mac() call _format_mac_addr() to do the formatting. Changed print_mac() to use unsigned char * to be consistent with net_device struct's dev_addr. Added buffer length overrun checking as suggested by Joe Perches.

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
