bouyer 6e08061c2a Supports hardware 802.1q VLAN tagging, per discussion on tech-net. The tag is
stored in a m_aux mbuf defined by AF_LINK, ETHERTYPE_VLAN.
Thanks to Jason & Itojun for the feedback.

thorpej fabbb33a60 Implement ether_ioctl(), ioctl operations common to all Ethernet
interfaces.

thorpej 96375e93ea Improve the VLAN support, in particular, handling of MTU:
- Add a macro to compute the max frame length based on Ethertype
  and presence of FCS, and use it to validate the packet size
  in ether_input().
- Add capabilites to struct ethercom, and allow hardware drivers
  to specify that they can handle the larger hardware MTU that
  VLANs require in order to strictly conform to 802.1Q.
- Make ether_ifdetach() clear out the link address and free all of
  the Ethernet multicast structures.

Also, rearrange the VLAN driver itself in preparation to supporting
other hardware types, including FDDI (which has 802.1Q VLAN capability).

enami bf888fcd19 Factor out and give a name to the common functionality to translate
sockaddr which represents a multicast address into an Ethernet address
or range of Etherenet addresses.

thorpej b99cf790df - Initialize ifp->if_baudrate to a sensible value when the interface is
attached.
- Add ether_crc32_be() and ether_crc_le(), common functions for computing
  the Ethernet CRC on arbitrary length buffers.  Nothing uses them yet,
  and these should be double-checked and probably re-implemented as
  table-driven functions.

data formats.

thorpej 3462650350 Define an Ethernet-specific flag which drivers can use to tell
the input routine that the CRC is included at the end of the frame.

itojun 118d2b1d4f IPv6 kernel code, based on KAME/NetBSD 1.4, SNAP kit 19990628.
(Sorry for a big commit, I can't separate this into several pieces...)
Pls check sys/netinet6/TODO and sys/netinet6/IMPLEMENTATION for details.

- sys/kern: do not assume single mbuf, accept chained mbuf on passing
  data from userland to kernel (or other way round).
- "midway" ATM card: ATM PVC pseudo device support, like those done in ALTQ
  package (ftp://ftp.csl.sony.co.jp/pub/kjc/).
- sys/netinet/tcp*: IPv4/v6 dual stack tcp support.
- sys/netinet/{ip6,icmp6}.h, sys/net/pfkeyv2.h: IETF document assumes those
  file to be there so we patch it up.
- sys/netinet: IPsec additions are here and there.
- sys/netinet6/*: most of IPv6 code sits here.
- sys/netkey: IPsec key management code
- dev/pci/pcidevs: regen

In my understanding no code here is subject to export control so it
should be safe.

drochner b86fdd7409 don't expose structures and prototypes to _STANDALONE programs 1999-04-09 09:32:51 +00:00
thorpej 9da505740a Define several constants related to the Ethernet protocol:
- ETHER_ADDR_LEN: length of Ethernet address (actually, we already defined
  this).
- ETHER_TYPE_LEN: length of the Ethernet header `type' field.
- ETHER_CRC_LEN: length of the Ethernet CRC (explorer got this already, mostly
because I forgot to commit these changes earlier).
- ETHER_HDR_LEN: total length of the Ethernet header
- ETHER_MAX_LEN: maximum length of an Ethernet frame, including header and CRC
- ETHER_MIN_LEN: minimum length of an Ethernet frame, including header and CRC

Define ETHERMTU and ETHERMIN (payload sizes) in terms of the above constants.

is 07b064e02e New ARP system, supports IPv4 over any hardware link.
Some of the stuff (e.g., rarpd, bootpd, dhcpd etc., libsa) still will
only support Ethernet. Tcpdump itself should be ok, but libpcap needs
lot of work.

For the detailed change history, look at the commit log entries for
the is-newarp branch.
