* [intel] Replace driver for Intel Gigabit NICsMichael Brown2012-04-2423-15729/+0Star

* [e1000] Request notification of TX completionsMichael Brown2011-12-061-1/+1
| | | | | | | | | | | | | | | | | | | The RS bit is used to instruct the NIC to update the TX descriptor status byte. The RPS bit is used to instruct the NIC to defer this update until after the packet has been transmitted on the wire (rather than merely read into the transmit FIFO). The driver currently sets RPS but not RS. Some e1000 models seem to interpret this as implying that the status byte should be updated; some don't. On the ones that don't, we never see any TX completions and so rapidly run out of TX buffers. Fix by setting the RS bit in the TX descriptor. (We don't care about when the packet reaches the wire, so don't bother setting the RPS bit.)

* [e1000] Remove unused variable when ICR register is simply clearedMichael Brown2011-03-165-12/+10Star
| | | | | | | | | | | | | On reset and close, the ICR register is read to clear any pending interrupts, but the value is simply ignored. Avoid assigning the value to a variable, to inhibit a warning from gcc 4.6. Also fix a potential race condition in reset routines which clear interrupts before disabling them.

* [build] Rename gPXE to iPXEMichael Brown2010-04-202-8/+8
| | | | | | | | | | | Access to the gpxe.org and etherboot.org domains and associated resources has been revoked by the registrant of the domain.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.

* [e1000] Update e1000 driverMarty Connor2010-03-1724-13857/+15347
| | | | | | | | | | | | This commit replaces the current gPXE e1000 driver with one ported from Intel source code available at http://sourceforge.net/projects/e1000/ which is upstream source for the Linux kernel e1000 drivers, and should support most if not all PCI e1000 variants.

| | | | | | | | | | | | The 82571 supports an alternate MAC address location in NVRAM. When this is set, use this for the MAC rather than the default physical MAC address.

* [e1000] Add 82576 supportSimon Horman2009-10-163-24/+181
| | | | | | | | | | | | | | | | | | | Add the 82576 to the e1000 driver. - Examining the Linux 2.6.30-rc4 igb driver, which supports this card and; - Information available in the Intel® 82576 Gigabit Ethernet Controller Datasheet v2.1, which is available from Intel's web site. I only have a dual-ported card with Copper PHY, so any code paths relating to Fibre haven't been tested. Also, I have only tested using auto-negotiation of speed and duplex, and no flow control. Other code paths relating to those settings also have not been exercised.

* [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().

* [e1000] Use PCI_BASE_ADDRESS_* symbols instead of integersMarty Connor2008-12-051-2/+2
| | | | | | | | | | | When compiling for the Linux kernel, PCI_BASE_ADDRESS_0 == 0, and PCI_BASE_ADDRESS_1 == 1. This is not so when compiling for gPXE. We must use the symbolic names rather than integers to get the correct values. Bug identified and patch supplied by: George Chou <george.chou@advantech.com>
* [i386] Change [u]int32_t to [unsigned] int, rather than [unsigned] longMichael Brown2008-11-192-22/+22
| | | | | | This brings us in to line with Linux definitions, and also simplifies adding x86_64 support since both platforms have 2-byte shorts, 4-byte ints and 8-byte long longs.

* [NETDEV] Add notion of link stateMichael Brown2008-04-221-0/+3
| | | | | | | | | | | 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.

* Correct e1000 interrupt routine to enable on 1 disable on 0. duh.Marty Connor2007-12-131-2/+2
| | | | | | The e1000_irq() routine should (per mcb30) do enable on non-zero, disable on zero. This is not consistent in all drivers, so I'll wait to update it when doing a global sweep.
