* [build] Rename gPXE to iPXEMichael Brown2010-04-201-4/+4
| | | | | | | | | | | Access to the gpxe.org and etherboot.org domains and associated resources has been revoked by the registrant of the domain. Work around this problem by renaming project from gPXE to iPXE, and updating URLs to match. Also update README, LOG and COPYRIGHTS to remove obsolete information.

* [netdevice] Add netdev_is_open() wrapper functionMichael Brown2010-03-231-1/+1

* [netdevice] Separate out the concept of hardware and link-layer addressesMichael Brown2009-08-121-1/+1
| | | | | | | | | | | The hardware address is an intrinsic property of the hardware, while the link-layer address can be changed at runtime. This separation is exposed via APIs such as PXE and EFI, but is currently elided by gPXE. Expose the hardware and link-layer addresses as separate properties within a net device. Drivers should now fill in hw_addr, which will be used to initialise ll_addr at the time of calling register_netdev().
* [ifmgmt] Move link-up status messages from autoboot() to iflinkwait()Joshua Oreman2009-06-241-7/+27
| | | | | | | | | | | | With the addition of link status codes, we can now display a detailed error indication if iflinkwait() fails. Putting the error output in iflinkwait avoids code duplication, and gains symmetry with the other interface management routines; ifopen() already prints an error directly if it cannot open its interface.

* [netdevice] Add mechanism for reporting detailed link status codesMichael Brown2009-06-241-0/+4
| | | | | | | | Expand the NETDEV_LINK_UP bit into a link_rc status code field, allowing specific reasons for link failure to be reported via "ifstat". Originally-authored-by: Joshua Oreman <oremanj@rwcr.net>
* [legal] Add a selection of FILE_LICENCE declarationsMichael Brown2009-05-181-0/+2
| | | | | Add FILE_LICENCE declarations to almost all files that make up the various standard builds of gPXE.
* [ui] Allow Ctrl-C to cancel wait for net device link-upMichael Brown2009-01-271-0/+9
| | | | | This really ought to be handled via monojob.c and the usual Ctrl-C mechanism that handles cancelling DHCP or file downloads.
* [netdevice] Retain and report detailed error breakdownsMichael Brown2008-11-081-2/+23
| | | | | | | | | | netdev_rx_err() and netdev_tx_complete_err() get passed the error code, but currently use it only in debug messages. Retain error numbers and frequencey counts for up to NETDEV_MAX_UNIQUE_ERRORS (4) different errors for each of TX and RX. This allows the "ifstat" command to report the reasons for TX/RX errors in most cases, even in non-debug builds.
* [NETDEV] Add notion of link stateMichael Brown2008-04-221-1/+23
| | | | | | | | | | | Add ability for network devices to flag link up/down state to the networking core. Autobooting code will now wait for link-up before attempting DHCP. IPoIB reflects the Infiniband link state as the network device link state (which is not strictly correct; we also need a succesful IPoIB IPv4 broadcast group join), but is probably more informative.
* Allow recording of TX and RX errors to aid in end-user debugging.Michael Brown2007-07-051-2/+3

* Add trivial net device statistics (TX and RX packet count), reportedMichael Brown2007-07-031-2/+3

* Use stdio.h instead of vsprintf.hMichael Brown2007-01-191-1/+1

* Add "name" field to struct device to allow human-readable hardware deviceMichael Brown2007-01-101-2/+3
| | | | | | | | | | | 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).
* Added network interface management commandsMichael Brown2007-01-101-0/+66
