I've been seeing "Unknown Object - Abort Decoding... (0x150a), 1 point" on some
packets. The devices being monitored don't report any problems. Looked in
DNP3Spec-V6-Part2-Objects-20080901 and Object Group 21 Variarion 10 is valid.
Checked wireshark source using svn web access and there are 3 mis-defined
constants.

338 #define AL_OBJ_FCTR_16NF 0x1510 /* 21 10 16-Bit Frozen Counter Without
Flag */
339 #define AL_OBJ_FDCTR_32NF 0x1511 /* 21 11 32-Bit Frozen Delta Counter
Without Flag */
340 #define AL_OBJ_FDCTR_16NF 0x1512 /* 21 12 16-Bit Frozen Delta Counter
Without Flag */
0x1510 should be 0x150a, 0x1511 should be 0x150b, 0x1512 should be 0x150c
