[c-nsp] tx-ring-limit on ISR ATM-AIM module...

[Derick Winkworth]

All:

I believe I may need to tune down the tx-ring on a 3845 with ATM-AIM 
module.  I'm looking at this, and it doesn't look like it uses the same 
system that the 7200 uses (i.e., with particles/576 bytes per particle 
calculation). 

from "show controller atm0/ima0" I see the following:

############
MXT5100 Channel Info:

    Channel Info (0):
      Chan_ID (0x1425), Open Status SUCCESS, VC(1)VPI/VCI(1/777),

      Rx CRC err(1), Rx cell CLP0(24771185), Rx cell CLP1(0)

So it looks like the tx-ring is just 40 "packets" long.  I'm assuming 
this means 40 AAL5 packets?   Does anyone know what "SBD" stands for?

I tried getting some tech docs on the MXT5100 from Conexant, but you 
need a support account to access that.
