[c-nsp] Etherchannels and member port load

Load in sh etherchannel detail does not represent the actual current
load on the interfaces, it represents the division of the hash
buckets across the member ports and is static once the channel is
configured (and membership is stable). It is a bit odd that it is 00
in your case though, it should look something like:
Index Load Port EC state No of bits
------+------+------+------------------+-----------
0 55 Gi3/1 On 4
1 AA Gi3/2 On 4
In binary you can see that the buckets are divided evenly between the
two ports.
0x55=b01010101
0xAA=b10101010
