Having forced __table() to natural structure alignment, it now seems
...
that we *can* place arrays in tables, which means we can force the
order within a table without having to resort to explicitly numbered
sections on everything.

Add "name" field to struct device to allow human-readable hardware device
...
names.
Add "dev" pointer in struct net_device to tie network interfaces back to a
hardware device.
Force natural alignment of data types in __table() macros. This seems to
prevent gcc from taking the unilateral decision to occasionally increase
their alignment (which screws up the table packing).

Allow udp_{send,sendto,sendto_via} to be called outside of the

udp_senddata() callback. This will simplify any UDP protocols that don't

DHCP transmits via specified net device, so no need to create a dummy

Add RX quotas to the net device poll() method. This avoids the problem
...
of alloc_pkb() exhaustion when e.g. an iSCSI-booted DOS session is left
idle for a long time at the C:\ prompt and builds up a huge packet
backlog.

Autopadding was sometimes overwriting the struct list_head at the end
...
of the packet buffer. Although pkbuffs are guaranteed to be at least
PKB_ZLEN bytes long, there's no guarantee that the data starts at the
start of the packet buffer.
Since we have to align data for rtl8139 anyway, and since the start of
the packet buffer is guaranteed to be aligned to PKB_ALIGN, we may as
well just shuffle the packet down so that it starts at the start of
the packet buffer. This simultaneously aligns the packet and ensures
that there is enough room for the zero-padding.

Leave protected-mode return address on PM stack when issuing a

real_call(), rather than moving it to the RM stack and back again.
This allows the real-mode function to completely destroy the stack

Define "connected" as
...
"when SYN is ACKed and we have already received SYN", or
"when SYN is received and we have already had SYN ACKed"
rather than just
"when SYN is ACKed"
This avoids spuriously calling the connected() method when we receive
a RST,ACK in response to a SYN.

We can't assert that the RX engine is idle in iscsi_done(), because it
...
may be called during the RX data processor, before the RX engine
transitions back to idle. It doesn't really matter if the RX engine
isn't idle when iscsi_done() is called, because it will just pick up
where it left off on the next call. (The same is not true for the TX
engine, so keep the TX engine assertion.)

Added UNDI root bus driver (which saves including all the PCI bus code,
...
UNDI ROM code etc. when you just want a "undi.kpxe"-type image).
This driver cannot be used in conjunction with any other driver (it will
crash), or in any other format than .kpxe (it just won't find any network
devices).

New strategy: always stop both base code and UNDI. Always free base code

memory (unless we get an error while stopping the base code). Leave UNDI

Still need to add code to record the device identification parameters
prior to stopping UNDI.
