boundaries.
* Only justify static fields and only scroll dynamic fields.
* Handle O_PUBLIC and O_VISIBLE flags when drawing field.
* Changes to support new curses window handling.
* Allow field options to be changed when field posted unless field
is the current one.
* Allow field justification to be changed when field posted unless it
is the current one.
* dynamic_field_info now returns field size in rows and columns if
the field is static - previously this was an error.
About the only bit of his code not here is the transmit routines, which I'll
merge in separately.
Also a few bug-fixes, so (for instance) multicast on an 8005 doesn't
immediately fall back to IFF_ALLMULTI.
This now provides slightly more functionality than the FreeBSD layer1-newbus
interface. It was meant to be a simple change to one header and a few
c files, but the change rippled all through various stuff.
To prevent a change to the kernel<->userland interface right now the kernel
is now lying about card types to userland (but who cares). This will be fixed
when the userland interface changes, after layer 3 <-> layer 4 has been
fixed.
Functional changes:
Provide a clean interface for hardware drivers to attach to the upper
layers. This will need another small change in the B-channel handling
when a similar change to the layer 3 <-> layer 4 interface happens.
Avoid passing indices into global arrays of pointers around, instead pass
the pointers itself. Don't code hardware driver types by predefined magic
numbers (think LKM). Prepare for detachable drivers (think pcmcia).
While there remove some sets of function pointers always pointing to the
same function (meant to be the configurable set of D channel protocol
handlers). It is unlikely another supported D-channel protocol will fit into
that (maximal layer interface) abstraction. When we get support for another
protocol, we will need to come up with a workable interface. Besides, the
old implementation was, uhm, strange.
have vmspace setup yet. This fixes lossage discussed on current-users,
thread "hard lockups with -current and Netscape", and should fix
kern/12433 by <kawamoto@tenjin.org>, maybe also kern/12455.
XXX Threads forked via linux_sys_clone() should share the brk value
XXX if they share vmspace. This needs to be implemented.
