a9a03de54d Pull up to ETHER_HDR_LEN before passing an mbuf to ether_input(). 
The bug was found by running ng_dummy(4) node configured with a
delay, in front of the ng_eiface(4) node.

5908d366fb Consistently use __inline instead of __inline__ as the former is an empty macro

212b6d5244 + rename and document an unused field in struct arpcom (field is still 
there so there are no ABI changes);
+ replace 5 redefinitions of the IPF2AC macro with one in if_arp.h

Eventually (but before freezing the ABI) we need to get rid of
struct arpcom (initially with the help of some smart #defines
to avoid having to touch each and every driver, see below).

Apart from the struct ifnet, struct arpcom now only stores a copy
of the MAC address (ac_enaddr, but we already have another copy in
the struct ifnet -- if_addrhead), and a netgraph-specific field
which is _always_ accessed through the ifp, so it might well go
into the struct ifnet too (where, besides, there is already an entry
for AF_NETGRAPH data...)

Too bad ac_enaddr is widely referenced by all drivers. But
this can be fixed as follows:

#define ac_enaddr       ac_if.the_original_ac_enaddr_in_struct_ifnet

(note that the right hand side would likely be a pointer rather than
the base address of an array.)

2fbf6cf055 MFS: Make struct arpcom the first entry in softc. (There are at least 
two functions in sys/net/if.c that assume that softc starts with arpcom.)
This makes setting of ethernet address via ifconfig(8) work as expected.

9bf40ede4a Replace the if_name and if_unit members of struct ifnet with new members 
if_xname, if_dname, and if_dunit. if_xname is the name of the interface
and if_dname/unit are the driver name and instance.

This change paves the way for interface renaming and enhanced pseudo
device creation and configuration symantics.
