It seems DoIO() fails after 6 sectors. Could it have something to do with side handling ? I hope I won't have to dig trackdisk.device specific stuff...
Anyway even with 6 sectors read, the boot code now calls _start() successfully. Use _floppy_err_alert() to assert this until the copying is fixed.

If no Haiku remote disk server is found, try an iSCSI discovery session on
the TFTP server, using the IP address from the boot command or OF options.
All available IPv4 targets are considered, Target Portal Groups are ignored.
RFC 4173 suggests a mechanism that avoids a discovery session by using DHCP;
that requires a compatibly configured DHCP server though and we wouldn't have
access to such data currently anyway. iSCSI is currently used as fallback,
and when it doesn't succeed it falls back to the menu as before.

Add support for both discovery and regular iSCSI sessions. Command and status
sequence numbers do differentiate between session and connection but only
one connection per session is currently supported.

Don't enqueue a packet whose sequence number matches the first one in queue
or is between the next and the acknowledged on. This would lead to packet
duplication in the queue and leftovers after dequeuing.
Optimize calculation of acknowledgement number for out-of-order reception.
If a single missing packet arrived, this could have resulted in a timeout
depending on the window size.
In case the connection is closed, do dequeue remaining packets. This would
have caused a read error after a unidirectional FIN.
Prepare a dynamic window size calculation.
Do checksum calculation before attempting to trace packet contents. I have
seen a few and couldn't spot an error in the checksum calculation.
More fine-grained control over trace output.
Trace the Maximum Segment Size option if present; break after End of Options.

Partially revert r38465 and move the code from system_time() into a new
real_time_clock_usecs() function. The system_time() implementation was correct
in relying on of_milliseconds(), as pointed out by Axel. Add the correct
function for the desired functionality.

Modelled after UDP, add limited TCP support to the boot net stack. The socket
works by queuing received packets as well as sent packets that have not yet
been ACK'ed. Some known issues are documented, especially there's only limited
congestion control. I.e., we send immediately and in unlimited quantity, thus
its use should be restricted to local networks, and due to a fixed window size
there is potential for our socket being overrun with data packets before they
are read. Some corner cases like wrapping sequence numbers may cause a timeout.
The TCP implementation is based on Andrew S. Tanenbaum's "Computer Networks",
4th ed., as well as lecture notes from Prof. W. Effelsberg, the relevant RFCs
and Wikipedia. The pseudo-random number Galois LFSR used for the sequence
number was suggested by Endre Varga.
Since the code is unlikely to get much smaller, better merge it now so that
subsequent changes get easier to review. No platform actively uses TCP sockets
yet, and the receiving code has been reviewed for endianness issues and should
terminate okay after verifying the checksum if no sockets are open.
Based on a version tested with custom code (#5240) as well as with iSCSI.
Compile-tested boot_loader_openfirmware, pxehaiku-loader with gcc4 and
haiku_loader with gcc2. Closes ticket #5240.
Changes from #5240 proposed patch:
* Various bug fixes related to queuing, some memory leaks fixed.
* Never bump the sequence number when dequeuing a packet. It's done afterwards.
* Don't bump the sequence number again when resending the queue or ACK'ing.
* Aggressively ACK while waiting for packets.
* Don't queue sent ACK-only packets.
* More trace output, esp. for queue inspection.
* Adapted use of TCP header flags to r38434.

system_time() was based on of_milliseconds(), which returns the number of
milliseconds since power-on. This would produce very similar or identical
results for subsequent boots due to limited clock resolution; therefore it
was unsuited as PRNG seed, e.g., for TCP ports.
Try to inquire the RTC device node with get-time to return an improved time
value, if possible.
Closes ticket #6061.
Changes from proposed patch:
* Obtain the RTC handle once and reuse it for each inquiry.

Use the OF "screen" device alias to query frame buffer properties. Postpone
the opening of the device as far as possible as it erases the screen output.
Initialize the kernel arguments and hook into generic code to display the
splash screen.
Like on x86, the frame buffer is enabled by default. To disable it, either
press ESC during early boot or, for debugging, make sure in start.cpp that
platform_boot_options() has the BOOT_OPTION_DEBUG_OUTPUT flag set.

Introduce a non-blocking function for checking keyboard input, and refactor
existing code to share the escape key translations. The comment that key-up and
key-down result in a zero char is confirmed to apply.
If the space bar is pressed, enter the boot menu. If the escape key is pressed,
disable the frame buffer and keep showing the usual debug output. Apparently
the key press must come after console/keyboard initialization but before the
"Welcome to the Haiku bootloader!" line.
Closes ticket #6140.

Debug output calls OpenFirmware methods writing text into the frame buffer.
Depending on the screen mode this leads to garbled display or parts of the
screen overwritten, so mute the output during frame buffer use for now.
A better solution would be to redirect the output elsewhere (e.g., #6168),
so that ConsoleHandle::WriteAt() is not called for the problematic handle
in the first place. That does not work inside the kernel yet.

Revert r36886 and fix compilation of insert_virtual_range_to_keep().
The use of void* vs. addr_t matches the surrounding boot loader code
but should probably be revised in favour of addr_t.
create_area() in the kernel wrongly assumed a RAM-backed address range,
which was destined to fail since ranges below the kernel address space
were ignored anyway. Use vm_map_physical_memory() instead.
This fixes a hang once the frame buffer and other resources used by OF
get unmapped. Closes ticket #5193 again.

turned out it's pretty much broken. Not only did it potentially leak memory,
it would also potentially replace the original data with a NULL pointer,
making the current transaction non revertable. The code should now be much
clearer. This fixes bug #6378.
* Changed a few "if (... != NULL)" into ASSERTs, since the code should bail out
earlier in these cases already.
* Added a TODO comment to cache_start_sub_transaction() about its broken discard
handling. This can cause FS corruptions in case the parent transaction is ever
going to be aborted (which shouldn't happen in real life, though).
* Added a bit more and better comments.

* got rid of get_rtc_info() and rtc_info struct in kernel, as it was only

interface - this caused quite a number of changes.
* Network interfaces, and its addresses are now reference counted (not yet
complete, though, InterfaceAddresses need to hold references to their
interface as well).
* There are two known regressions of this commit that I will fix later:
- you cannot remove interfaces anymore
- IPv4 multicast was broken anyway, but now it's disabled, too.
* Moved a device_interfaces.cpp|h out of interfaces.cpp.
* The datalink layer chain is now instantiated per domain per interface,
not just per interface anymore.
* When a buffer reaches the network layer, it has no known interface yet, ie.
the ipv4|6|whatever modules need to set this manually.
* Added more debug output, and some new debugger commands, the control option
is now printed in clear text.
* Added hash_address() function to the address modules. Added "const" to
set_to_defaults() where needed.
* Fixed net_buffer's restore header functions offset use as reported by Atis.
* Improved buffer dump output, use the domain module to print the address if
available.
* Moved net_buffer::type into the union, as it's not needed by the upper layers
anymore.
* Moved IPv6 specific code from {add|remove}_default_route() to where it
belongs, but disabled it for the time being.
* Completely discarded useless ipv4_datagram module.
* Added ping6 to the build.
