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).

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
contents, provided that it manages to return to real_call().

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.
