Hi! I'm running Linux with an IBM Turbo 16/4 Token-Ring ISA Adapter running in LANAIDC /FAST=AUTO16 compatibility mode, and I seem to be getting diminished performance and an occasional message in my syslog as follows: tr0: xmit ret_code: 23 xmit error code: 00 Does anybody know what ret_code 23 means? Is there a tuning parm that I can use? Any help would be appreciated! Mike
