The current SKID length configuration causes firmware

AST table SKID length configuration is increased to
maximum value to fix this issue.
If your firmware is like 10.1, then probably AST length should
really be same as config.num_peers?
10.1 firmware definitely has same or similar issue in it's
AST table handling, for what that is worth.
Thanks,
