Auke Kok 2cc304923d e100: add PCI Error Recovery
Various PCI bus errors can be signaled by newer PCI controllers.  This
patch adds the PCI error recovery callbacks to the intel ethernet e100
device driver. The patch has been tested, and appears to work well.

Jesse Brandeburg aa49cdd93b e100: fix eeh on pseries during ethtool -t
Olaf Hering reported a problem on pseries with e100 where ethtool -t would
cause a bus error, and the e100 driver would stop working.  Due to the new
load ucode command the cb list must be allocated before calling
e100_init_hw, so remove the call and just let e100_up take care of it.

Jesse Brandeburg 471ef051bc e100: remove init_hw call to fix panic
e100 seems to have had a long standing bug where e100_init_hw was being
called when it should not have been.  This caused a panic due to recent
changes that rely on correct set up in the driver, and more robust error
paths.

ODonnell, Michael ac7c66698a [PATCH] corruption during e100 MDI register access
We have identified two related bugs in the e100 driver.

Both bugs are related to manipulation of the MDI control register.

The first problem is that the Ready bit is being ignored when writing to
the Control register; we noticed this because the Linux bonding driver
would occasionally come to the spurious conclusion that the link was down
when querying Link State.  It turned out that by failing to wait for a
previous command to complete it was selecting what was essentially a random
register in the MDI register set.  When we added code that waits for the
Ready bit (as shown in the patch file below) all such problems ceased.

The second problem is that, although access to the MDI registers involves
multiple steps which must not be intermixed, nothing was defending against
two or more threads attempting simultaneous access.  The most obvious
situation where such interference could occur involves the watchdog versus
ioctl paths, but there are probably others, so we recommend the locking
shown in our patch file.

Jesse Brandeburg 2afecc047e [PATCH] e100: re-enable microcode with more useful defaults
For the four versions of hardware that we (currently) support microcode
download on, the default configuration of our receive interrupt mitigation
microcode was too aggressive, and caused unnecessary delays when pinging,
and low(er) throughput on single connection latency sensitive performance
tests.

This code adds microcode support, and sets the defaults to more reasonable
settings. It also explains the functionality in the code in more detail.
Compile and load tested, shows expected behavior for slight delay of ping
packets (1-2ms) when ucode is loaded, and decent interrupt moderation for
small packets, while maintaining good throughput.

Linus Torvalds 1da177e4c3 Linux-2.6.12-rc2
Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
