- more stat counters (rxmbufout -- mbufs, ttrash -- trashed RBD)
- add swsl_size to keep track of size of software slist
- revise when we call en_service
- fix handling of circular lists (was getting full vs empty confused in
extreem cases...)
- native mode atm: remove sbappend code: can't do it here since
socket buffer is protected only by splsoftnet and that doesn't
mask enintr off. forces us to switch to a two level interrupt
scheme. revise call to atm_input to reflect that.
[1] rxslot "cur" pointer wasn't updated if we copied all data and
didn't have any fill. this could cause a service id mismatch
panic under load.
[2] recv of aal0 forgot to include the cell header in the data length
calc [add cell header length to midwayreg.h]
[3] fix control info "chop" for raw mode and aal0
[4] handle rxsb better for native atm connections
(XXX: still working on this ... not complete and needs revision)
