The Software Porting And Archive Centre for HP-UX now has libpcap 0.6.2

binaries, so users only need to make sure they have that version
installed in order to have Ethereal (and tcpdump, and snort, and so on)
accept "lanN"-style names (i.e., names of the sort reported by lanscan
and handled by ifconfig), rather than "dlpiN".

Get rid of the patches to update libpcap, get rid of the discussion in
"README.hpux" of patching libpcap and just say "get 0.6.2", and make the
notes on HP-UX kernel patches to fix problems with capturing outgoing
packets a separate item in the list of items in "README.hpux".

Also update the error messages Ethereal and Tethereal display if they
can't open a device and the error is "can't find PPA for XXX" to say
"get 0.6.2" rather than "patch libpcap and recompile.

-
-  "To access a particular interface, you would say "tcpdump -i /dev/dlpiN"
-  where N is the PPA of the interface you wish to use. You get the PPA by
-  looking at the output of lanscan. On 10.20, it is the same value as the
-  NMID. On 11.X, it is the Card Instance number."

-It appears that a consequence of the fact that HP-UX's DLPI doesn't work
-like Solaris's, in that, on Solaris, to get at the device "hme0", say,
-"libpcap" has to open "/dev/hme" and then tell it to use the 0th

-get a list of interfaces in the dialog box for "Capture:Start" - you'll
-have to do through the aforementioned song and dance to find the PPA of
-the interface you want to use, and supply the "dlpiN" name by hand (I
-think you can omit the "/dev/" in both tcpdump and Ethereal).
-
-Here is a patch to "pcap-dlpi.c" in libpcap that, at least on HP-UX
-11.X, allows the name of the network interface, rather than the "dlpiN"
-name, to be specified to tcpdump and Ethereal.
-
-On HP-UX 11.00, the patch allows a network interface to be specified by
-name as an argument to tcpdump, rather than requiring that you specify a
-"dlpiN" name (and it should work equally well with Ethereal).

-If you try this code on HP-UX 10.20, and it doesn't let you specify the
-interface by name, please send mail to ethereal-dev@ethereal.com, so
