The first argument to "ascii_print_with_offset()", "ascii_print()", "hex_print_with_offset()", and "hex_print()" is a string used as a tag; make it a "const char *", not a "const u_char *". Copy the declaration of "strsep()" from "interface.h" to "netdissect.h", and get rid of the include of "interface.h" from "print-esp.c", as it includes "netdissect.h".

Add a flag to suppress the "default_print()" call made in various link-layer print routines if no other print routine claimed the packet. Test whether that flag is set rather than testing whether neither of -x or -q were specified, and have -x, -q, *and* -X set that flag, so that -X suppresses it just as -x does. That way you don't get those pckets dumped twice if -X was specified.

Add a -h flag, and only attempt to recognize 802.11s mesh headers if it's set. I give up. I have no access to the 802.11s drafts, I can't find anything that suggests whether a heuristic check for an 802.11s header should check for To DS and From DS both being set or either being set or unset, or whether it should check for a QoS frame type (the examples in all the documentation I can find have To DS and From DS set, and have a QoS field, in the 802.11 header, but that might just be an example 802.11 header showing all the fields), so I'm just adding a -h command-line flag; you need to specify it to get tcpdump to try to guess whether a frame has a mesh header or not. I'll leave it up to somebody else to figure out what the best heuristic for detecting the presence of mesh headers is (note that tcpdump and Wireshark have different heuristics, both of which can probably get false positives, especially with encrypted frames where the first payload byte just *happens* not to have any of the reserved bits in the mesh header flags set).

Have "ascii_print()" do the "-A" output, and nothing but the "-A" output. Have "hex_and_ascii_print_with_offset()" and "hex_and_ascii_print()" to the "-X"-style offset, leaving "hex_print_with_offset()" and "hex_print()" doing the "-x"-style output. Don't have any of them check "xflag", "Xflag", or "Aflag" - they print what they're intended to print, and the caller should check the flags in question. Don't have "-A" set "xflag" or "Xflag". This cleans up some problems with "-A" printing hex informatioin - it's not supposed to.

The first argument to "ascii_print_with_offset()", "ascii_print()", "hex_print_with_offset()", and "hex_print()" is a string used as a tag; make it a "const char *", not a "const u_char *". Copy the declaration of "strsep()" from "interface.h" to "netdissect.h", and get rid of the include of "interface.h" from "print-esp.c", as it includes "netdissect.h". Update the "ND_TTEST2()" macro to do the same overflow checks that "TTEST2()" now does.

Go with Wireshark's Internet checksum routine. The Wireshark routine is based on the BSD in-kernel portable checksum routine (thus BSD-licensed); it takes a vector of pointers and lengths and checksums the concatenation of the buffers in question (just as the BSD in-kernel routine checksums a chain of mbufs). This simplifies the "with a pseudo-header" checksums; hopefully it'll fix up the problems being seen on some big-endian platforms, which might be due to hand-calculating some or all of the checksum and doing so incorrectly. It also gets rid of some code that might be dereferencing unaligned pointers.
