Seeing a flood of LLC packets dropped by firewall?

I'm seeing a ton of network traffic that the firewall is dropping, the only info it is capturing is:

Ethernet Header
Ether Type: 0x27(0x27), Src=[00:25:64:1b:cf:1b], Dst=[01:80:c2:00:00:00]
Ethernet Type: Unknown
Value:[0]
DROPPED, Drop Code: 1(Unknown Ether type.), Module Id: 16(fwCore), (Ref.Id: _2706_kprwvJqqm) 1:1)

Eth Type: LLC(0x27)

Anyone know what these packets are?
