specified to "--with-pcap", add that directory to the include file and
library search paths, so that you can use "--with-pcap=DIR" to search
for libpcap in a directory other than the standard ones (either because
it was installed somewhere other than under "/usr" or "/usr/local", or
because you want to use a special version you've installed rather than
the standard one).

don't bother fetching it if the action is E_DECODE_NO; that means we can
also avoid fetching the currently selected row if the action is
E_DECODE_NO, so the fact that we've cleared the selection if the action
is E_DECODE_NO doesn't matter.

include, for example, "dllexport"-type declarations) rather than the
"workaround for platforms that lack it" declaration.

Don't bother doing the WEP processing and child-tvbuff construction for
frames other than management and data frames, as they have no payload to
be WEP-encrypted or dissected.

that you can open up that protocol without opening up the 802.11 MAC
header; this can save some screen real estate.
Make the tree item for all the WEP parameters a text item, rather than a
"string" field with a null string pointer, as "strings" with null string
pointers give the filtering code gastric distress.
Dissect the WEP initialization vector as an FT_UINT24 (as it's a 3-byte
field), and dissect the key ID as part of an FT_UINT8 (as it's in an
8-bit byte).
After dissecting the frame control field, dissect the rest of the header
in one switch statement, and then:
handle WEP-encrypted frames with common code for all frame
types;
handle the payload of other frames.
(If we can supply the relevant keys to Ethereal, we could perhaps add
code to decrypt the WEP payload and then dissect the decrypted payload
the same way we dissect un-encrypted payloads.)

#defining all the bits in the flags field, and using those #defines in

Make routines not used outside this module static.

integral value from a packet - "tvb_get_letohs()" can do that just fine.
Don't use "tvb_get_ptr()", casting the result to a "guint16 *", and
dereferencing that pointer, either: that doesn't handle byte order
correctly, and it may fail if the pointer isn't aligned on a 2-byte
boundary.
For that matter, don't just use "tvb_get_ptr()" and dereference the
result to get an 8-bit quantity.
Use "proto_tree_add_item()" in many places where it's possible.
Reuse the results of "tvb_get_ptr()" calls when possible.
Show the fragment number and sequence number in decimal - they're just
ordinals.
Fix the blurb for the sequence number field.

and put it under the top-level 802.11 protocol item, so you don't have
to open the frame control field to see it.
Rename the variable for it, and the value_string array for it, to
indicate that it's made out of the type and subtype fields.

Clear-to-send frames, or....
Compute the composed frame type early in the dissection process, and set
the Info column as soon as you've done that, rather than doing it in the
later switch statement.

protocol tree; not only is putting it at the top level a little weird,
it upsets the heck out of the protocol-statistics code, causing it to
abort. Put the fixed and tagged parameters under the top-level entry
for 802.11 (where one of the fixed-parameters entries already was).
Call the top-level item just "IEEE 802.11", not "IEEE 802.11 Header", as
it includes management-frame information.

interpretation of the address fields, in DATA_ADDR_T{1,2,3,4} format.
Clean up a bunch of other macros to enclose their argument in
parentheses.
Clean up "find_header_length()" - it only needs to take the frame
control field of the frame as an argument, and should just check whether
"COOK_ADDR_SELECTOR()" returns DATA_ADDR_T4.
"tofrom_ds" is a value_string table, not a true_false_string table, so
wrap it in "VALS()", not "TFS()".
Don't fetch the header length in N different places in the main
dissector - just fetch it once and use it throughout.

routine.
