It was not noticed during tests because at that point %si points

terminator for the string and a non printable character.

because FreeBSD's boot1 does not use it, but other systems might.
(I have been struggling for almost a full day trying to figure out
why a syslinux'ed partition would not boot when started with the
FreeBSD /boot/boot0, only to realize that the bug was ours!)
The space for the two extra bytes (push %si and pop %si) is reclaimed
by removing an extra CRLF that is printed before booting.
The bug is not a major one but if there is time it might be a good
thing to merge it into the upcoming releases.

o Configure controller to use dynamic TBD as TSO requires that
operation mode.
o Add a dummy TBD to tx_cb_u as TSO can access one more TBD in TSO
operation.
o Increase a DMA segment size to 4096 to hold a full IP segment
with link layer header.
o Unlike other TSO capable controllers, 82550/82551 does not
modify the first IP packet in TSO operation so driver should
create an IP packet with proper header. Subsequent IP packets
are generated from the header information in the first IP packet
header. Likewise pseudo checksum also should be computed by
driver for the first packet.
o TSO requires one more TBD to hold total TCP payload. To make
code simple for TSO/non-TSO case, increase the index of the
first available TBD array.
o Remove KASSERT that checks the size of a DMA segment should be
less than or equal to MCLBYTES as it's no longer valid in TSO.
o Tx threshold and number of TBDs field is used to store MSS in
TSO. So don't set the Tx threshold in TSO case.
82559 or later controllers added simple checksum calculation logic
in RU. For backward compatibility the computed checksum is appended
at the end of the data posted to Rx buffer. This type of simple
checksum calculation support had been used on several vendors such
as Sun HME/GEM, SysKonnect GENESIS and Marvell Yukon controllers.
Because this type of checksum offload support requires parsing of
received frame and pseudo checksum calculation with software
routine it still consumes more CPU cycles than that of full-fledged
checksum offload controller. But it's still better than software
checksum calculation.
Rx buffer and loads DMA map. Also add a function
fxp_discard_rfabuf that handles reusing Rx buffer/DMA map. With
this change fxp_add_rfabuf just handles appending a new RFA to
existing chain.
o Initialize mbuf length in fxp_new_rfabuf.
o Don't reset rnr and have fxp(4) handle received frames even if
it couldn't allocate new Rx buffer. This will make fxp(4) reload
updated RFA under rnr case. The rnr would still be reset to 0 if
polling is active and fxp(4) processed number of allowed Rx
events.
o Update if_iqdrops if fxp(4) couldn't allocate Rx buffer.
Previously fxp(4) used to try to reuse Rx buffer when new buffer
allocation is failed. But fxp(4) didn't take into account loaded
DMA map such that the same DMA map was loaded again without
unloading the map. There is no reason to unload the loaded map and
reload the same map again, just reusing the map is enough. I
believe the spare DMA map in softc was introduced to implement this
behaviour. Also fxp(4) used to stop Rx processing if once Rx buffer
allocation or DMA map load fails which in turn resulted in losing
incoming frames under heavy network load. With this change fxp(4)
should survive from resource shortage condition.

- Don't count number of mbuf chains. Default 32 DMA segments for a
frame is enough for most cases. If bus_dmamap_mbuf_sg fails use
m_collapse(9) to collapse the mbuf chain instead of relying on
expensive m_defrag(9).
- Move bpf handling to fxp_start_body() which is supposed to be
more appropriate place.
- Always arm watchdog timer whenever a new Tx request is made.
Previously fxp(4) used to arm watchdog timer only when
FXP_CXINT_THRESH-th Tx request is made. Because fxp(4) does not
rely on Tx interrupt to reclaim transmitted mbufs it's better to
arm watchdog timer to detect potential lockups.
- Add more aggresive Tx buffer reclaiming in fxp_start_body to make
room for new Tx requests. Since fxp(4) does not request Tx
completion interrupt for every frames it's necessary to clean
TXCBs in advance to saturate link.
- Make fxp(4) try to start more packets transmitting regardless of
interrupt type in fxp_intr_body.
