igb: fix LRO warning

2009-06-15T16:40:11+00:00

This fix is only needed for 2.6.29.y tree, since in 2.6.30 and later IGB
has moved to using GRO instead of LRO.

igb supports LRO, but was not setting any hooks to the ->set_flags
ethtool_ops function.  This would trigger warnings if the user tried
to enable or disable LRO.

Based on the patch provided by Stephen Hemminger

igb: remove ASPM L0s workaround

2009-03-15T05:26:40+00:00

The L0s workaround should be moved into a pci quirk and so it is not
necessary in the driver.  This update removes the L0s workaround from the
igb driver.

This was the second half of the PCI quirk patch that Matthew Wilcox did
not pick up when he picked up the quirk patch.

igb: fix link reporting when using sgmii

2009-01-31T08:53:18+00:00

When using sgmii the link was not being properly passed up to the driver
from the underlying link management functions.  This change corrects it so
that get_link_status is cleared when a link has been found.

igb: prevent skb_over panic w/ mtu smaller than 1K

2009-01-31T08:52:57+00:00

A panic has been observed with frame sizes smaller than 1K.  This has been
root caused to the hardware spanning larger frames across multiple buffers
and then reporting the original frame size in the first descriptor.  To
prevent this we can enable set the LPE bit which in turn will restrict
packet sizes to those set in the RLPML register.

igb: Fix DCA errors and do not use context index for 82576

2009-01-31T08:52:30+00:00

82576 was being incorrectly flagged as needing a context index.  It does not as
each ring has it's own table of 2 contexts.

Driver was registering after registering the driver instead of the other way around.

igb: fix anoying type mismatch warning on rx/tx queue sizing

2009-01-06T02:47:12+00:00

When using "min()", the types of both sides should match.  With the cpu
mask changes, the type of num_online_cpus() will now depend on config
options. Use "min_t()" with an explicit type instead.

And make the rx/tx case look the same too, just for sanity.

igb: re-order queues to support cleaner use of ivar on 82576

2008-12-26T09:34:11+00:00

The 82576 adapter orders the queues in pairs when virtualization is in use.
The queue ordering previously conflicted with the ordering when sr-iov was
enabled.  This new ordering allows a PF to allocate 2 queues without using
any VF resources.

igb: defeature tx head writeback

2008-12-26T09:33:18+00:00

This patch removes tx head writeback as it was found to not provide a
significant improvement in tx performance and on some systems has been seen
to cause a performance degredation due to partial cache line writes.
