e1000e: use resource_size_t, not unsigned long, for phys addrs

2008-05-22T10:19:32+00:00

The use of unsigned long causes the driver to fail on 32-bit systems
which support 64-bit resources.

e1000e: don't return half-read eeprom on error

2008-05-06T16:38:02+00:00

On a read error, e1000e might have returned uninitialized block of
eeprom data back to userspace. The convention is that 0xff is "empty",
so mark the entire eeprom as empty in case of an error.

e1000e: Add support for BM PHYs on ICH9

2008-05-06T16:04:14+00:00

This patch adds support for the BM PHY, a new PHY model being used
on ICH9-based implementations.

This new PHY exposes issues in the ICH9 silicon when receiving
jumbo frames large enough to use more than a certain part of the
Rx FIFO, and this unfortunately breaks packet split jumbo receives.
For this reason we re-introduce (for affected adapters only) the
jumbo single-skb receive routine back so that people who do
wish to use jumbo frames on these ich9 platforms can do so.
Part of this problem has to do with CPU sleep states and to make
sure that all the wake up timings are correctly we force them
with the recently merged pm_qos infrastructure written by Mark
Gross. (See http://lkml.org/lkml/2007/10/4/400).

To make code read a bit easier we introduce a _IS_ICH flag so
that we don't need to do mac type checks over the code.

e1000e: save and restore pcie/msi state to support EEH recovery

2008-04-25T06:08:04+00:00

To enable EEH support for pci-express network adapters, pcie/msi state
needs to be saved and restored for that adapter.

Tested this EEH patch with 2ports and 4ports pci-express e1000e
adapters.

e1000e: lower ring minimum size to 64

2008-04-25T06:07:13+00:00

The lower limit of 80 descriptors in the ring is only valid for
one older 8254x chipset. All e1000e devices can use as low as
64 descriptors.

e1000e: Fix HW Error on es2lan, ARP capture issue by BMC

2008-04-25T06:07:12+00:00

Several components to this complex fix. The es2lan cards occasionally
gave a "HW Error" especially when forcing speed. Some users also
reported that the BMC stole ARP packets.

The fixes include setting the proper SW_FW bits to tell the BMC
that we're active and not do any un-initialization at all, so the
setup routine is largely changed.

e1000e: Add interrupt moderation run-time ethtool interface

2008-04-25T06:07:12+00:00

The ethtool -c / -C interface can now be used to modify the
irq moderation algorithm. This change does not require an
adapter reset and can thus be used at all times. The adapter
only supports changing/reading rx-usecs which has special
values for 0, 1 and 3:

0 - no irq moderation whatsoever
1 - normal moderation favoring regular mixed traffic (default)
3 - best attempt at low latency possible at cost of CPU

For values between 10 and 10000 the rx-usecs defines "the minimum
time between successive irqs" in usec, unlike the module parameter.

e1000e: cleanup several stats issues

2008-04-25T06:07:11+00:00

Several stats registers are completely unused and we just waste pci
bus time reading them. We also omit using the high 32 bits of the GORC/
GOTC counters. We can just read clear them and only read the low registers.

Mii-tool can also break es2lan if it executes a MII PHY register
ioctl while the device is in autonegotiation. Unfortunately it seems
that several applications and installations still perform this ioctl
call periodically and especially in this crucial startup time. We
can fool the ioctl by providing fail safe information that mimics
the "down" link state and only perform the dangerous PHY reads once
after link comes up to fill in the real values. As long as link
stays up the information will not change.

e1000e: reformat register test code, fix some minor initialization

2008-04-17T00:41:37+00:00

The register tests should be run with all the proper flags enabled
to maximize the test coverage code and make sure we are as close
as we can get to testing regular traffic.

Reformat the code for readability. Minor cleanups in the descriptor
ring setup.
