7e4e5af462 Use RFC4390 whenever hardware address exceeds 16 bytes; this allows us 
to construct DHCP packets suitable for Infiniband.

2ff1b1245b Use start_timer_nodelay() in protocols which rely on the retry timer 
to generate the initial transmission; this cuts off around 0.3s per
instantiated connection.

847ac4f336 tls_change_cipher() can complain about null cipher and digest 
algorithms; we only need the pubkey check disabled (and only because
pubkey algorithms are not yet integrated into the crypto_algorithm

47a86bca2d Prepare for iBFT merge when possible. iscsiboot.c contains a really, 
really ugly hack at present, but that doesn't hugely matter since I'm
aiming to change the interface to iSCSI devices anyway within the next
week.

4c418d2100 Use net_device_operations structure and netdev_nullify() to allow for 
safe dropping of the netdev ref by the driver while other refs still
exist.

Add netdev_irq() method.  Net device open()/close() methods should no
longer enable or disable IRQs.

Remove rx_quota; it wasn't used anywhere and added too much complexity
to implementing correct interrupt-masking behaviour in pxe_undi.c.

b8618d76db Modify data-xfer semantics: it is no longer necessary to call one of 
request(), seek() or deliver_xxx() in order to start the data flow.
Autonomous generators must be genuinely autonomous (having their own

starting the retry timer immediately.

4e20d73bb5 Gave asynchronous operations approximate POSIX signal semantics. This 
will enable us to cascade async operations, which is necessary in order to
properly support DNS.  (For example, an HTTP request may have to redirect
to a new location and will have to perform a new DNS lookup, so we can't
just rely on doing the name lookup at the time of parsing the initial
URL).

Anything other than HTTP is probably broken right now; I'll fix the others
up asap.

76aa9ad07d Make TCP give up immediately when it receives -ENETUNREACH from 
tcpip_tx().  This avoids the irritating wait when you accidentally type
"kernel pxelinux.0" before bringing up the network interface.

Add ENETUNREACH to strerror()'s list.

c953c1a1c3 Use -ENETUNREACH to mean "no reachable network device exists, don't bother 
retrying".

ad22cccc09 No need to maintain a received byte count; we always fill in sequential 
order so we can just use buffer->fill.

dad5274522 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).
