Clean up the various different email addresses of mine listed in the code to a single current and valid address. As Dave says his network merges for 2.6.28 are now done this seems a good point to send them in where they won't risk disrupting real changes.

2008-10-13de2104x: wrong MAC address fixMartin Langer
The de2104x returns sometimes a wrong MAC address. The wrong one is like the original one, but it comes with an one byte shift. I found this bug on an older alpha ev5 cpu. More details are available in Gentoo bugreport #240718. It seems the hardware is sometimes a little bit too slow for an immediate access. This patch solves the problem by introducing a small udelay.

2008-09-24tulip: Fix dead 21041 ethernet after ifconfig downThomas Bogendoerfer
The de2104x did a pci_disable_device() in it's close function, but the open function never does a pci_enable_device() and assumes that the device is already enabled. Considering that downing the interface is just a temporary thing the pci_disable_device() isn't a pretty good idea and removing it from the close function just fixes the bug.

2008-06-12net: Eliminate flush_scheduled_work() calls while RTNL is held.David S. Miller
If the RTNL is held when we invoke flush_scheduled_work() we could deadlock. One such case is linkwatch, it is a work struct which tries to grab the RTNL semaphore. The most common case are net driver ->stop() methods. The simplest conversion is to instead use cancel_{delayed_}work_sync() explicitly on the various work struct the driver uses. This is an OK transformation because these work structs are doing things like resetting the chip, restarting link negotiation, and so forth. And if we're bringing down the device, we're about to turn the chip off and reset it anways. So if we cancel a pending work event, that's fine here. Some drivers were working around this deadlock by using a msleep() polling loop of some sort, and those cases are converted to instead use cancel_{delayed_}work_sync() as well.

2008-05-22uli526x: add support for netpollAnton Vorontsov
This patch adds netpoll support for the uli526x ethernet driver -- simply call the interrupt handler for polling. To do this without disable_irq()/enable_irq() pair we should fully protect the handler. Luckily, it's already using irqsave spinlock, the only unprotected place is interrupts re-enabling write. It was safe to re-enable interrupts without holding the spinlock, but with netpoll possibility now it doesn't seem so. Patch was tested using netconsole and KGDBoE.

2008-04-16[netdrvr] tulip: Better MWI workaround for 21143 rev 65 chip errataPeter Horton
This patch works around the MWI bug on the DC21143 rev 65 Tulip by ensuring that the receive buffers don't end on a cache line boundary (as documented in the errata). This patch is required for the MIPS based Cobalt Qube/RaQ as supporting the extra PCI commands seems to reduce the chance of a hard lockup between the Tulip and the PCI bridge.

2008-04-16[netdrvr] tulip/winbond-840: don't let tulip.h symbol stomp oursJeff Garzik
winbond-840 shares tulip.h with the tulip driver, because they share many (but not all) of the same register definitions. This is useful for the register definitions, but not helpful when it comes to symbols that are shared among the tulip driver's C modules, but not meant to be shared outside that one driver. Thus, PKT_BUF_SZ is a symbol internal to tulip, but it was intruding upon a similar symbol in winbond-840's namespace. This was not a problem as long as the two symbols had the same value, but upcoming patches result in differing symbol values. Signed-off-by: Jeff Garzik <jgarzik@redhat.com>

2008-03-28[netdrvr] tulip_read_eeprom fixes for BUG 4420Grant Grundler
If "location" is > "addr_len" bits, the high bits of location would interfere with the READ_CMD sent to the eeprom controller. A patch was submitted to bug: http://bugzilla.kernel.org/show_bug.cgi?id=4420 which simply truncated the "location", read whatever was in "location modulo addr_len", and returned that value. That avoids confusing the eeprom but seems like the wrong solution to me. Correct would be to not read beyond "1 << addr_len" address of the eeprom. I am submitting two changes to implement this: 1) tulip_read_eeprom will return zero (since we can't return -EINVAL) if this is attempted (defensive programming). 2) In tulip_core.c, fix the tulip_read_eeprom caller so they don't iterate past addr_len bits and make sure the entire tp->eeprom[] array is cleared. I konw we don't strictly need both. I would prefer both in the tree since it documents the issue and provides a second "defense" from the bug from creeping back in.

Changeset 16b110c3fd760620b4a787db6ed512fe531ab1b5 (dmfe warning fix) bothed up the offsets read from the SROM so that it doesn't read the same datums it used to. The change made transformations like turning: "srom + 34" into "(__le32 *)srom + 34/4" which doesn't work because 4 does not divide evenly into 34 so we're using a different pointer offset than in the original code. I've changed theses cases in dmfe_parse_srom() to consistently use "(type *)(srom + offset)" preserving the offsets from the original code. Signed-off-by: David S. Miller <davem@davemloft.net>

This provides a more uniform behavior across all drivers, eliminating ethtool(8) "ioctl not supported" errors on older drivers that had not been updated for the latest sub-ioctls.
