[c-nsp] Netflow export error from C6506 (WS-X6704-10GE)

[Stas Bakulin]

Hello!

We have a problem with exporting netflow from WS-X6704-10GE (with
DFC3CXL) line cards.
ICAM used for 99% and TCAM not used.

#sh mls netflow table-contention summary

====================================================
TCAM Utilization             :   1%
ICAM Utilization             :   99%
Netflow Creation Failures    :   131564
Netflow CAM aliases          :   0

In the same router netflow export from SUP720 module is ok.

Have tried software upgrade from SXI4a to SXH7, problem still existed.
