Limit xmit window to one MTU. (Path MTU discovery not yet
implemented; should be done at some point.)

pkbuff->iobuf changeover
Achieved via Perl using:
perl -pi -e 's/pk_buff/io_buffer/g; s/Packet buffer/I\/O buffer/ig; ' \
-e 's/pkbuff\.h/iobuf.h/g; s/pkb_/iob_/g; s/_pkb/_iob/g; ' \
-e 's/pkb/iobuf/g; s/PKB/IOB/g;'

Use total free memory as advertised window. This seems to be sufficient
to avoid drops even on slow NICs.

anyone?

Use whole bytes for the ACKED and RCVD portions of tcp_state; it
produces slightly smaller code.

Redefine TCP state to include "flags that have been sent" rather than
"flags that are currently being sent". This allows at least one special
case (checking that we haven't already sent a FIN in tcp_rx_fin()) to be
collapsed.

both IPv4 and IPv6 addresses.

orders of magnitude.

Header rearrangement.
I want to get to the point where any header in include/ reflects a
standard user-level header (e.g. a POSIX header), while everything that's
specific to gPXE lives in include/gpxe/. Headers that reflect a Linux
header (e.g. if_ether.h) should also be in include/gpxe/, with the same
name as the Linux header and, preferably, the same names used for the
definitions.
