Replace CHECKSUM_HW by CHECKSUM_PARTIAL (for outgoing packets, whose
checksum still needs to be completed) and CHECKSUM_COMPLETE (for
incoming packets, device supplied full checksum).
Patch originally from Herbert Xu, updated by myself for 2.6.18-rc3.

A recent patch in -mm3 titled
"gregkh-pci-pci-don-t-enable-device-if-already-enabled.patch" causes
pci_enable_device() to be a no-op if the kernel thinks that the device is
already enabled. This change breaks the PCI error recovery mechanism in
the e1000 device driver, since, after PCI slot reset, the card is no longer
enabled. This is a trivial fix for this problem. Tested.

The commit 'e1000: Remove 0x1000 as supported device' (Jeff Kirsher,
673a052fde) Removes PIC device ID 8086:1000
from the list of supported devices. A fix was submitted for the original
issue (commit 6a9516989f).
This commit reverts commit 673a052fde and
re-enables 82542rev3 chips completely.

Commit 581d708eb4 (oct. 5 2005) introduced
partial Multiqueue support for e1000 which broke macro smartness in setting
up head/tail registers for 82542 rev3 chipsets, making these adapters
completely non-working since 2.6.15.
This commit sets the proper head and tail registers for read and write
descriptor rings. Ths fix was tested on an 82542 rev3 NIC and newer NICs.
