[c-nsp] Drop rule at the end of CoPP conflicts with MAC learning

["Rolf Hanßen"]

Hi Nick,

does not look like this is a general hardware version issue.

the bad box:
Mod  Port Model              Serial #    Versions
---- ---- ------------------ -----------
-------------------------------------
  5    2  WS-SUP720-3B       ########### Hw : 5.3
                                         Fw : 8.5(1)

                                         Sw1: 8.7(0.22)SXH11
          WS-SUP720          ########### Hw : 2.6
                                         Fw : 12.2(17r)SX7
                                         Sw : 12.2(33)SXH
          WS-F6K-PFC3B       ########### Hw : 2.3

the good #1:

                                         Sw : 12.2(33)SXH2
                                         Sw1: 8.7(0.22)BUB25
          WS-SUP720          ########### Hw : 2.5
                                         Fw : 12.2(17r)S4
                                         Sw : 12.2(33)SXH2
          WS-F6K-PFC3B       ########### Hw : 2.3

the good #2:
Mod  Port Model              Serial #    Versions
---- ---- ------------------ -----------
-------------------------------------
  6    2  WS-SUP720-3BXL     ########### Hw : 4.1
                                         Fw : 8.5(2)
                                         Sw : 15.1(2)S
                                         Sw1: (sierra_main_dev)1.0.5
          WS-SUP720          ########### Hw : 2.2
                                         Fw : 12.2(17r)SX5
                                         Sw : 15.1(2)S
          WS-F6K-PFC3BXL     ########### Hw : 1.8


But I found a box with the same hardware versions:

Mod  Port Model              Serial #    Versions
---- ---- ------------------ -----------
-------------------------------------
  5    2  WS-SUP720-3B       ########### Hw : 5.3
                                         Fw : 8.4(2)
                                         Sw : 12.2(33)SXJ
                                         Sw1: 20.1(1)SXJ
          WS-SUP720          ########### Hw : 2.6
                                         Fw : 12.2(17r)SX7
                                         Sw : 12.2(33)SXJ
          WS-F6K-PFC3B       ########### Hw : 2.3

This box also works as soon as I enter "mls rate-limit unicast cef glean
500".

kind regards
Rolf
