Re: [Linux-ATM-General] ForeRunnerHE errors/configuration

well it certainly seems that you have exceeded the expections of the
default tuning.  the default configuration for the card is a guess at
what the averge user might need.

the HBUF_ERR means that the card ran out of receive buffers.  since you
are just terminating ethernet/ip you can change CONFIG_RBPL_BUFSIZE to
2048 and then double CONFIG_RBPL_SIZE (to 1024).  the maximum ethernet
frame wont be any bigger than 1500 or so.  if you still have trouble
try raising CONFIG_RBPL_SIZE (double it) and #undef USE_RBPS.  you
should probably double the RBRQ_SIZE as well (it should probably be
atleast the max of CONFIG_RBPL_SIZE or CONFIG_RBPS_SIZE).

tpdrq getting full means the transmit list for the card was full.
double TPDRQ_SIZE to 1024.  if that doesnt fix, double it again to 2048.
the TBRQ_SIZE should probably be the same size as the TPDRQ_SIZE.
