b34d4d0449 Separate the "is data ready" function of xfer_seek() into an 
xfer_window() function, which can return a scalar rather than a
boolean.

ca4c6f9eee Kill off unused request() method in data-xfer interface. 2007-07-08 02:10:54 +01:00

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.

30a442aef8 Report our interface type as "gPXE" to avoid working around Etherboot 
5.4 bugs when driving ourselves via UNDI.

1ce0b4bbfb Kill off PXENV_UNDI_FORCE_INTERRUPT support; we have no reason to 
suspect that we need it, and implementing it would require needlessly
complicating the net device API.

5f92f0bd82 Reserve space for link-layer header in pxenv_undi_transmit() when not 
handed a P_UNKNOWN packet.

258afef751 Add missing call to free_iob() in pxenv_undi_isr(). 
Correct typo in pxenv_set_station_address().

4968caab82 Add trivial net device statistics (TX and RX packet count), reported 
via UNDI API and also by ifstat command; may be useful for debugging.

cbd956535e Place netdev_open()/netdev_close() calls in appropriate places. 2007-07-03 00:02:06 +01:00

e42eba4af4 Use a common base-memory packet buffer for DHCP construction (as used 
by PXE and NBI) and UNDI packets (as used by undinet and UNDI).

5f17089b14 pxe_netdev now holds a reference to the network device. 
Use generic fields in struct device_description rather than assuming
that the struct device * is contained within a pci_device or
isapnp_device; this assumption is broken when using the undionly
driver.

Add PXENV_UNDI_SET_STATION_ADDRESS.

e3bbfd7a75 Call shutdown() from pxenv_undi_shutdown(). Probably not totally 
correct, but it's enough to get RIS working.

8130443f9f Separate out pxe_start_nbp() from pxe_image.c into pxe_call.c 
Implement PXENV_RESTART_TFTP.

e381714c07 Partial migration of UDP to data-xfer interface. (Will not link at 
present; DHCP is broken).
 2007-06-20 01:13:35 +01:00

01b4bde8a0 Updated TFTP and PXE UDP API code to use not-yet-implemented data-xfer 
UDP API.

a5a330339b Split DBG() statement containing two inet_ntoa() statements; they 
return a static buffer.

d4894f0127 We *should* use the persistent reference API for our netdev reference, 
but there's so much else missing that it's not worth doing right now.

84a2b886e1 Split error-message table portions of errno.h out to gpxe/errortab.h 2006-12-20 03:40:48 +00:00

88e38fa148 We don't actually have a stdio.h header file. Our printf() functions are 
defined in vsprintf.h.  (This may change, since vsprintf.h is a
non-standard name, but for now it's the one to use.)

There should be no need to include vsprintf.h just for DBG() statements,
since include/compiler.h forces it in for a debug build anyway.

6ac78f6aff added stdio.h to includes for DBG compilation 2006-09-27 05:57:06 +00:00

f018da8215 Implement enough of PXENV_GET_CACHED_INFO to support pxelinux. 2006-08-09 02:59:19 +00:00
Michael Brown
75d26d884a Added pxe_netdev; a slight hack for now, but will need to be done 
properly for the PXE UNDI API anyway.
 2006-08-09 02:58:27 +00:00

691557281f Add a couple of small but vital parts to PXENV_UDP_WRITE. 2006-08-09 01:57:02 +00:00

ffe0e24249 Make the UDP senddata() methods return a status code. 
udp_connect() now follows the standard BSD sockets semantics and simply
sets the default address for outgoing packets; it doesn't filter incoming
packets.

a0a872f7f1 Updated PXE UDP implementation to use the new Etherboot UDP API. 
Updated PXE API dispatcher to use copy_{to,from}_user, and moved to
arch/i386 since the implementation is quite architecture-dependent.
(The individual PXE API calls can be largely
architecture-independent.)

832e86246b gcc is rather over-aggressive about optimising out static data structures 
even when __atribute__ (( unused )) is correctly set...
