Among other, add ARPHRD_ARCNET definition, make sure the hardware type is
set on outgoing ARP packets, make sure we dont send out replies as broadcasts.
Jonathan Stone and myself. Many thanks to Matt Thomas for providing
the information necessary to implement this interface, and for helping
to shake out the bugs.
Some of the stuff (e.g., rarpd, bootpd, dhcpd etc., libsa) still will
only support Ethernet. Tcpdump itself should be ok, but libpcap needs
lot of work.
For the detailed change history, look at the commit log entries for
the is-newarp branch.
in. Unfortunately, the BPF-only code called a label that wan't also
being #if'ed, and this made the compiler bitch. Now that we compile
with -Werror, this prevented the thing from compiling at all! (sigh)
"The mapping of IP Class D addresses to local addresses is
currently specified for the following types of networks:
[...]
o Any network that supports broadcast but not multicast,
addressing: all IP Class D addresses map to the local
broadcast address."
* Fix radio error-message parsing bug: old comparison against error
prefix string off by the size of the Starmode link-level protocol field.
* Fix radio reset finite state machine, given that parsing works properly.
* Add debugging messages about reset FSM if IFF_DEBUG is set.
* Remove #ifdefs notdef around back the check that discards newlines at
the beginning of a frame. Every error message from the radio has a newline,
as the radio send error messages terminated by \r\n, not just \r like data
frames. Not dropping the \n garbles the following data frame.
* Remove unused low-level debugging routines.
* Reformat the low-level bytestuff/RLL code to match the canonical source.
* Reduce MTU to 1100 bytes; 1200 bytes can overflow the radio buffers if the
bytestuff/RLL does poorly.
* Fix radio-probe string to _not_ include a frame delimiter (\r): sending
a \r to the radio tickles a bug in the firmware, causing the radio to
smash the next frame sent after the "**\r" probe string.
* Add calls to the tty t_oproc routine to make sure the probe and reset
strings get sent to the modem promptly, rather than waiting for the next
packet.
* Add PPP-style calls to the tty start-output function; seems to
reduce latency marginally.
still to do:
* Flush output queue if resetting, since the radio is going to drop
frames on the floor anyway if it needs resetting.
* Reduce tty start-output calls.
