[c-nsp] WS-X6724-SFP & SXI = high cpu usage?

[Tassos Chatzithomaoglou]

For everyone interested, the outcome is that WS-X6724-SFP or WS-X6748-SFP need to have a lot (~15-20) of SFPs connected 
in order for the cpu to increase.

CSCsr21196:  x6724/x6748 SFP enhanced link detection method
The link background aggressively polls 24 ports at a poll. There is no toggle to turn it on or off.
