The previous code could wrongly delete multicast groups
on the parent interface. Now we forward only remembered
delete requests.

to bpf with either an address family or other header added.
These helpers only allocate a much smaller struct m_hdr on the stack when
needed, rather than leaving 256 byte struct mbufs on the stack in deep
call paths. Also removes a fair bit of duplicated code.

consume vlan frames that no vlan interface wants, so they can
still be bridged.
This way, the bridge can bridge encapsulated frames _and_ bridge
between vlan interfaces.

bits from tags extracted from received frames. (Some drivers may
already do this masking internally, but doing it here doesn't hurt
and insures consistency.)
- In vlan_ioctl(), don't let the user set a VLAN ID value with anything
besides the VLID bits set, otherwise we will have trouble matching
an interface in vlan_input() later.

- Do not call if_down() on a parent interface if it's already down.

argument. old cred only calls user suser_ucred. this will allow future
work to more flexibly implement the idea of a root process. looks like
something i saw in freebsd, but a little different.
use of suser_ucred vs suser in file system code should be looked at again,
for the moment semantics remain unchanged.

- mask of vlan tag to ensure upper bit isn't present from hardware
- avoid mbuf leak on error
- make sure sizeof(ether_header) bytes are present in the firest mbuf
before passing it up to ether_input()
|
|
Fix multicast bug; internal multicast members' list was not initialized
correctly. Also, begin to make vlan less ether specific - TR and FDDI
could also be supported.

this works better than what we have now, although i have not been
able to extensively test it. several folks thought it should be added

header with the 802.1Q header. The reason for this is if_vlan is called
by the bridge (via if_start). It cannot modify the mbuf because it might
be shared copy.

LINK0 disappears; we now set IFCAP_VLAN_HWTAGGING at ifnet->if_capabilities
in the Ethernet driver for cards/drivers which support hardware tagging.
MTU ambiguity disppears; we now set IFCAP_VLAN_MTU in the Ethernet driver
when we know the chip will not truncate/discard vlan-sized frames.
Only allow the MTU to be changed within the scope of the parent interface's
MTU. (Here we also take into account IFCAP_VLAN_MTU)
Propagate hardware-assisted IP/TCP/UDP checksumming flags to the vlan interface
if the card supports hardware tagging (from NetBSD)

the new model removes direct references to the fields in ifp->if_snd,
and defines the following macros to manipulate ifp->if_snd.
IFQ_ENQUEUE(ifq, m, pktattr, err)
IFQ_DEQUEUE(ifq, m)
IFQ_POLL(ifq, m)
IFQ_PURGE(ifq)
IFQ_IS_EMPTY(ifq)
the new model also enforces some rules regarding how to use these macros.
details are descrined in

on how macros should be treated. Code by fgsch@, ok by me and itojun@
|
|
|
|
- call ether_input_mbuf() instead of ether_input()
- most work done by fgsch
|
|
and the tag doesn't match a child interface, reinsert the tag and call
ether_input() so that bridges can still function.
