The attached (.diff) patch provides support for dissection of 802.16e-2005
related TLVs in WIMAXASNCP plugin (with a small change in WIMAX plugin)

The WIMAXASNCP (plugin) dissector is currently unable to decode, beyond the
default hex dump, the 802.16e-2005 related TLVs. However, the WIMAX
plugin(contributed by Intel) is able to do so. The existing modules in WIMAX
plugin can be used to dissect the 802.16e-2005 related TLVs in WIMAXASNCP
plugin.

On encountering any 802.16e-2005 related TLVs, the program checks the existence
of WIMAX plugin. If present, the modules in the WIMAX plugin are used for
dissection. Otherwise, the TLVs are decoded as hex-dumps(as they are being done
right now). Although, this leads to a bit of coupling between the two plugins
but this does not create any problem even in absence of WIMAX plugin.

After application of patch(attached), the WIMAXASNCP plugin would be able to
dissect following TLVs in addition to those already supported:
