This is controlled by a per-adapter sysctl hw.atm.hfaX.shape. When
set to 0, no shaping occures. When set to 1 at most 1 channel is
shaped. When set to 2 all CBR channels are shaped. Note, that the
latter may actually not work, because of the adapter supporting
the shaping of only one PDU at the same time.
also do it). Three problems have been encountered:
1. The initialisation command does not work in interrupt mode. Whether
this is a firmware bug or a feature is not clear. The original Fore
drivers execute the initialize command always in polling mode, so
it appears that this behaviour is expected. When we detect a 4.X.Y
firmware do busy wait on the command status.
2. The command code of the GET_PROM command has changed. This is an
unofficial command anyway. What was GET_PROM in 3.X.Y is CLEAR_STATS
in 4.X.Y (although unimplemented in the firmware). We need to
use the correct code depending on the firmware.
3. The 4.X.Y firmware can set the error flag in the command status
without also setting the completion flag (as the documenation says).
Check both variants.
An additional field in the per-card structure fu_ft4 is TRUE when we have
detected a 4.X.Y firmware. Otherwise it is false. The behaviour of the
driver when using a 3.X.Y firmware should be identical to the previous
behaviour.
This change will enable traffic shaping of (at least one) CBR channels.
the necesary uma_zcreate() and uma_zdestroy calls into module loading
handler and the device attach handling.
- Change the related HARP netatm code to use UMA zone functions when
dealing with the zones that were formerly the ATM interface (hea, hfa)
storage pools.
- Have atm_physif_freenifs() now get passed an uma_zone_t so that we can
properly free the allocated NIF's back to their zone.
This should be the last commit to remove any code that makes use of the
netatm storage pool api. I will be removing the api code within the near
future.

Define the NETISR just like all the other NETISRs.
unifdef -Usun -D__FreeBSD__ we will probably never support sun4c
and if we do we can't use the solaris code anyway and I doubt
anybody will be running Fore ATM cards in then in the first place.
