Struct ifatm isn't at the beginning of the softc anymore. Use the

correct way (IFP2IFATM()) to access it.

Stop embedding struct ifnet at the top of driver softcs. Instead the

2005-06-10T16:49:24+00:00

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.

Split the chip-specific code from the generic Utopia code. This simplifies

adding of new physical chips. Now one just needs to add a .h and a .c
file for the new chip and add one line to utopia.c for that chip.

A number of modules return EINVAL in this instance, and I have left
those alone for now and instead taught MOD_QUIESCE to accept this
as "didn't do anything".

Generate events when the carrier goes up or down.

Add two sysctl's that allow read-only access to the current
state of the utopia interface and to the carrier state.

Implement statistics for the PHY chips. Statistics are hold in

2003-07-14T15:06:53+00:00

64-bit counters that wrap on overflow. They are collecte once per
second from the chips. Currently they can be retrieved via a sysctl phy_stats.
A write of an arbitrary value to the sysctl atomically retrieves the
statistics and clears them.

Add support for the IDT77155 Sonet/SDH PHY.
