onoe 2819c7b688 Use DMA from mbuf instead of copy in transmit.
Still use memcpy in receiving because we must use buffer fill mode
	and many packets may share single receive buffer.

XXX: Workaround(?) for CXD3222: it fails to DMA for selfid packet according
to code placement. I'm not sure about the reason (cache? timing? bug?).

Fixed the bug: transmitter sometimes stop and OACTIVE bit of if_fw
never be cleared.
Fixed the bug: freeing free buffer.

Enable ieee1394_drain and ieee1394_watchdog for loss of fragment.

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.

bouyer 0d0fd7718e Per discussion with Jason, change flags filter to
(IFF_UP | IFF_BROADCAST | IFF_RUNNING | IFF_ALLMULTI | IFF_SIMPLEX)
Also, put the ifp->if_opackets++ at the rigth place so that the counter is
incremented even when the parent is OACTIVE.
Fix a bug in vlan_input where the ethernet src and dst addrs would not be
correct because we only memmove() only ifv->ifv_encaplen instead of
sizeof(struct ether_header).

onoe f1c77e81db Add support for link fragmentation and reassemble for IEEE-1394.
XXX: drain is still not yet implemented, thus memory leak will occur
    in case of any of fragment lost.

bouyer 3659b305e5 In vlan_config(), filter flags inherited from parent interface to
(IFF_UP | IFF_BROADCAST | IFF_RUNNING | IFF_ALLMULTI | IFF_SIMPLEX)
Without this, if the parent is OACTIVE of PROMISC at config time, we
loose.

thorpej 65fd25ea82 Restructure the PFIL_HOOKS mechanism a bit:
- All packets are passed to PFIL_HOOKS as they come off the wire, i.e.
  fields in protocol headers in network order, etc.
- Allow for multiple hooks to be registered, using a "key" and a "dlt".
  The "dlt" is a BPF data link type, indicating what type of header is
  present.
- INET and INET6 register with key == AF_INET or AF_INET6, and
  dlt == DLT_RAW.
- PFIL_HOOKS now take an argument for the filter hook, and mbuf **,
  an ifnet *, and a direction (PFIL_IN or PFIL_OUT), thus making them
  less IP (really, IP Filter) centric.

Maintain compatibility with IP Filter by adding wrapper functions for
IP Filter.

onoe e83458422f First Prototype implementation of network interface part for IEEE1394 (if_fw).
Current status:
	Only OHCI chip is supported (fwohci).
	ping (IPv4) works with Sony's implementation (SmartConnect) on Win98.
	sometimes works but not stable.
Not implemented yet:
	IRM (Isochronous Resource Manager) functionality.
	Link layer fragmentation.
	Topology map.
More to do:
	clean ups
	MCAP
	charactor device part
	dhcp

There is no entry in GENERIC config file yet.
Follow sys/dev/ieee1394/IMPLEMENTATION to enable if_fw.

2000-10-03 23:50:52 +00:00
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).

Note that:
- IANA assignment was made for AES
- we still have some time window till AES gets finalized, so until it gets
  finalized, we are not certain if AES == rijndael
but it should now be okay.
