5d691e6da8 Return mbuf pointer or NULL from ip_fastforward() as the mbuf pointer
may have changed by m_pullup() during fastforward processing.

While this is a bug it is actually never triggered in real world
situations and it is not remotely exploitable.

118b438d73 Get rid of the bogus IFP2FC() macro and use IFP2FWC(). IFP2FC()
attempted to cast a struct ifnet to a struct fw_com which resulted in
data corruption.

4a0d6638b3 - Store pointer to the link-level address right in "struct ifnet"
rather than in ifindex_table[]; all (except one) accesses are
  through ifp anyway.  IF_LLADDR() works faster, and all (except
  one) ifaddr_byindex() users were converted to use ifp->if_addr.

- Stop storing a (pointer to) Ethernet address in "struct arpcom",
  and drop the IFP2ENADDR() macro; all users have been converted
  to use IF_LLADDR() instead.

680d937a4b Be pedantic here: We're converting from network byte order to host
byte order in these cases.  This is a nop in terms of the generated
code, but is logically incorrect.

530f95fc08 o Make rt_check() function more strict:
- rt0 passed to rt_check() must not be NULL, assert this.
  - rt returned by rt_check() must be valid locked rtentry,
    if no error occured.
o Modify callers, so that they never pass NULL rt0
  to rt_check().

13f4c340ae Propagate rename of IFF_OACTIVE and IFF_RUNNING to IFF_DRV_OACTIVE and
IFF_DRV_RUNNING, as well as the move from ifnet.if_flags to
ifnet.if_drv_flags.  Device drivers are now responsible for
synchronizing access to these flags, as they are in if_drv_flags.  This
helps prevent races between the network stack and device driver in
maintaining the interface flags field.

Many __FreeBSD__ and __FreeBSD_version checks maintained and continued;
some less so.

9bd8ca3014 In preparation for fixing races in ARP (and probably in other
L2/L3 mappings) make rt_check() return a locked rtentry.

fc74a9f93a Stop embedding struct ifnet at the top of driver softcs. Instead the
struct ifnet or the layer 2 common structure it was embedded in have
been replaced with a struct ifnet pointer to be filled by a call to the
new function, if_alloc(). The layer 2 common structure is also allocated
via if_alloc() based on the interface type. It is hung off the new
struct ifnet member, if_l2com.

This change removes the size of these structures from the kernel ABI and
will allow us to better manage them as interfaces come and go.

Other changes of note:
 - Struct arpcom is no longer referenced in normal interface code.
   Instead the Ethernet address is accessed via the IFP2ENADDR() macro.
   To enforce this ac_enaddr has been renamed to _ac_enaddr.
 - The second argument to ether_ifattach is now always the mac address
   from driver private storage rather than sometimes being ac_enaddr.

46e3b1cbe7 Add two missing includes and remove two uneeded.
This is quite serious fix, because even with MAC framework compiled in,
MAC entry points in those two files were simply ignored.

b8b3323469 Add a new driver to support IP over firewire. This driver is intended to
conform to the rfc2734 and rfc3146 standard for IP over firewire and
should eventually supercede the fwe driver. Right now the broadcast
channel number is hardwired and we don't support MCAP for multicast
channel allocation - more infrastructure is required in the firewire
code itself to fix these problems.
