[c-nsp] Supported number HWIC-2FE cards in 2811

[Andrew Jones]

"supported" means that if you called TAC to log an issue with this setup, they would not allow the case to proceed until one of the cards was removed to bring the router to a supported configuration.

Many features are like this, for instance BGP on a 3750 a while back was unsupported, but could be configured. (this may or may not still be the case)

I recently picked up some HWIC-2FE and 1FE cards. For fun I stuck two
HWIC-2FE cards and one HWIC-1FE card into a lab 2811. To my surprise, it
started up indicating 7 Ethernet interfaces and properly identified all
interfaces in the config.

According to Cisco* the maximum supported HWIC-2FE cards for the 2811 is
one; I installed two. So what then does "supported" mean? In the past
for unsupported WIC/HWIC cards I expected "router will complain about an
invalid hardware config", but in this case all the HWIC ports were
recognized.
