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

[Seth Mattinen]

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.
