Fixes:
- flow control - don't override user value on re-init
- fix to make 1G optics work correctly
- change to interrupt enabling - some bits were incorrect
for certain hardware.
- certain stats fixes, remove a duplicate increment of
ierror, thanks to Scott Long for pointing these out.
- shared code link interface changed, requiring some
core code changes to accomodate this.
- add an m_adj() to ETHER_ALIGN on the recieve side, this
was requested by Mike Karels, thanks Mike.
- Multicast code corrections also thanks to Mike Karels.
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.
- add some new hardware support for 82599
- Big change to interrupt architecture, it now
uses a queue which contains an RX/TX pair as
the recipient of the interrupt. This will reduce
overall system interrupts/msix usage.
- Improved RX mbuf handling: the old get_buf routine
is no longer synchronized with rxeof, this allows
the elimination of packet discards due to mbuf
allocation failure.
- Much simplified and improved AIM code, it now
happens in the queue interrupt context and takes
into account both the traffic on the RX AND TX
side.
- variety of small tweaks, like ring size, that have
been seen as performance improvements.
- Thanks to those that provided feedback or suggested
changes, I hope I've caught all of them.
-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.
