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.

IPv6 on an sppp interface. In an IPv6-enabled kernel, every IPv6 interface automatically gets an IPv6 address assigned (and IPv6 multicast packets sent at initialization time). For sppp links where we know our remote peer wouldn't support IPv6 at all, there's no point in attempting to negotiate IPV6CP (or to even dial out for an IPv6 packet at all for dial-on-demand interfaces). I wish there were a more generic way to administratively disable IPv6 on an interface instead. ume told me there isn't. While i was at it, converted both, enable_vj and enable_ipv6 into flag bits in struct sppp (enable_vj used to be an int of its own). MFC after: 1 month

inclusion of VJ compression into sppp. Now, instead of the need to include this and that and everything plus the kitchensink in each of those drivers, struct sppp uses struct slcompress as an opaque structure only referenced by a pointer. The actual structure is then malloced at initialization time. While i was at it, also fixed a bug where received VJ packets would only be recognized if INET6 was defined.

time from the PPP packets sent. This effectively merges rev 1.2 of the old i4b_ispppsubr.c, with the exception that i eventually ended up in debugging and fixing it so the idle time is now really detected. ;-) (The version in i4b simply doesn't work right since it still accounts for incoming LCP echo packets which it is supposed to ignore for idle time considerations...)

This allows it to keep struct sppp inside #ifdef _KERNEL (where it belongs), and prevents userland programs that wish to include from including the earth, the hell, and the universe before the are able to resolve all the kernel-internal stuff that's in struct sppp. Discussed with: hm MFC after: 1 month

This is the logical merge of rev 1.32 of i4b's old if_spppsubr.c (which was based on PR misc/11767), plus (i4b) rev 1.6 of i4b's if_ispppsubr.c, albeit with numerous stylistic and cosmetic changes. PR: misc/11767 Submitted by: i4b, Joachim Kuebart MFC after: 1 month
