[j-nsp] LLDP bug, or EX bug?

I am not sure if this is an EX-specific issue, but the value of LLDP
when configuring 802.3ad is configured on an EX 4200 appears to be
rather limited.  Perhaps the RE does not know which port received a
message because the PFE masks it, or maybe JUNOS handles it poorly.

j3k1>show lldp neighbors                    
LocalInterface Chassis Id        Port info     System Name
ae3.0          00:11:21:f2:5c:85  ge-1-1-2.j3k1 g2s1
ae3.0          00:11:21:f2:5c:86  ge-0-1-2.j3k1 g2s1

Also, extra messages with different capability information are received
from the EX 4200 in the case of 802.3ad groups:

g2s1.1250rl#show lldp neighbors | include j3k1
j3k1                Gi1/0/5        120        B               134
j3k1                Gi1/0/6        120        R               206
j3k1                Gi1/0/5        120        R               176

While this is nowhere close to the top of my list of EX 4200 complaints,
I have not seen any mention of it on "the Google."
