(which should be a PCIE Gen 3 slot for this adapter) by looking back thru the PCI
parent devices to the slot device.
The fix above also corrects the bandwidth display to GT/s rather than the
incorrect Gb/s
Next, allow the use of ALTQ if you select the compile option IXGBE_LEGACY_TX.
Allow the use of 'unsupported' optic modules by a compile option as well.
Add a phy reset capability into the stop code, this is so a static configured
driver will still behave properly when taken down (not being able to unload it).
This revision synchronizes the shared code with Intel internal current code,
and note that it now includes DCB supporting code, this was necessitated by
some internal changes with the code, but it also will provide the opportunity
to develop this feature in the core driver down the road.
I have edited the README to get rid of some of the worse anachronisms in it
as well, its by no means as robust as I might wish at this point however.
Oh, I also have included some conditional stuff in the code so it will be
compatible in both the 9.X and 10 environments.
Performance has been a focus in recent changes and I believe this revision
driver will perform very well in most workloads.
MFC after: 2 weeks
crusty, and this still isn't perfect, but its at least a bit
more recent.
Secondly, a few improvements to the driver from Andrew Boyer,
support hint to allow devices to not attach, add VLAN_HWTSO
capability so vlans can use TSO, fix in the interrupt handler
to make sure the stack TX queue is processed. Oh, and also
make sure IPv6 does not cause a re-init in the ioctl routine.
Thanks for your efforts Andrew!
Thanks to Claudio Jeker for noticing the ixgbe_xmit() routine
was not correctly swapping the dma map from the first to the
last descriptor in a multi-descriptor transmission, corrected
this.
-It has new hardware support
-It uses a new method of TX cleanup called Head Write Back
-It includes the provisional generic TCP LRO feature contributed
by Myricom and made general purpose by me. This should move into
the stack upon approval but for this driver drop its in here.
-Also bug fixes and etc...
MFC in a week if no serious issues arise.
