Michael Brown 8624fdc445 Kill off the enforced RX quota; it only seems to hurt on real hardware. 2007-07-14 00:30:11 +01:00
Michael Brown 57b5e227ff Use fast in-situ test for gate A20 being set, to cut down on the 
number of (potentially very slow) gateA20_set operations.

Die with a fatal error if we are unable to set gate A20; if this fails
then we are bound to experience memory corruption at a later stage,
and I'd prefer to pick it up early.

Michael Brown eb530845d4 Adjust received length to take into account any already-received data 
in tcp_rx_data().

Michael Brown d5735c631c Avoid reusing auto-allocated ports after connection close. 2007-07-13 11:25:00 +01:00
Michael Brown 2ac7694c3e Improve error reporting for strange length combinations reported by 
the UNDI stack.

Ignore obviously invalid length combinations (as returned by
e.g. VMWare's PXE stack).

Limit to one packet per poll to avoid memory exhaustion.

Michael Brown efd322091d Set up %ds *before* testing a value in our data segment (d'oh!). 
Always send EOI; do not chain to BIOS's default interrupt handler.
They are just too unpredictable; at least VMware's seems to kill the
machine if you go anywhere near it.

Disable interrupts after return from PXENV_UNDI_ISR, just in case some
dumb PXE stack enables them.

Michael Brown e505ceb942 Revert "Cope with builds with differing debug options within a second of each" 
This reverts commit fc5f6c9de2.

Reverted commit breaks the much more common case of changing the debug
options in subsequent builds without any code changes.
 2007-07-07 17:49:07 +01:00
Michael Brown 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.

starting the retry timer immediately.

To maintain the guarantee that an object won't go out of scope
unexpectedly while one of its event handlers is being called, the
event-calling functions now automatically obtain and drop extra
references.
