igb: make certain to reassign legacy interrupt vectors after reset

2010-02-04T17:49:31+00:00

This change corrects an issue that will cause false hangs when using either
82575 or 82580 in legacy interrupt mode.  The issue is caused when there is
a slow traffic flow and an "ethtool -r" is executed while using legacy or
MSI interrupts.  MSI-X is not affected by this issue due to the fact that
we were already reconfiguring the vectors after reset.

If possible it would be best to push this for net-2.6 since it is resolving
a bug but if that is not possible then net-next-2.6 will be fine.

net: Fix IPv6 GSO type checks in Intel ethernet drivers

2010-01-23T10:02:21+00:00

Found this problem when testing IPv6 from a KVM guest to a remote
host via e1000e device on the host.
The following patch fixes the check for IPv6 GSO packet in Intel
ethernet drivers to use skb_is_gso_v6(). SKB_GSO_DODGY is also set
when packets are forwarded from a guest.

igb/igbvf: cleanup exception handling in tx_map_adv

2010-01-23T09:35:00+00:00

After removing the skb_dma_map/unmap calls the exception handling in
igb_tx_map_adv is not correct.  The issue is that the count value was not
being correctly handled so as a result we were not rewinding the ring as
back as we should have been.

igb: check both function bits in status register in wol exception

2009-12-24T04:47:51+00:00

The ethtool code for enabling Wake on Lan was not correctly checking the
status register bits so as a result ports 0 and 2 were both being allowed
to set WOL to enabled even though it is only supported on the first port
for our adapters.

igb: correctly offset 82575 flow control watermarks by 16 bytes

2009-12-24T04:47:50+00:00

The watermark values for the 82575 were not being set correctly.  As a
result the high and low watermark values were set to the same value which
can lead to excess xon/xoff packets being generated.

igb: do not force retry count to 1 on 82580 phy

2009-12-24T04:47:50+00:00

This change resolves an issue seen in some configurations where the link
may drop to 100Mb/s even though the link itself supports 1000Mb/s.  The
issue was root caused to the fact that we were only trying the link once.
Now instead we will try up to 5 attempts on a faulty cable before
downshifting to 100Mb/s.

igb: do not force pcs link when in KX mode

2009-12-24T04:47:49+00:00

We were forcing the PCS link up in error when we are in KX mode.  We should
only be disabling autoneg, not forcing the link up.

igb: remove use of skb_dma_map from driver

2009-12-03T03:57:12+00:00

This change removes skb_dma_map/unmap calls from the igb driver due to the
fact that the call is incompatible with iommu enabled kernels.  In order to
prevent warnings about using the wrong unmap call I have added a
mapped_as_page value to the buffer_info structure to track if the mapped
region is a page or a buffer.
