- Update to the latest (1.4.18) f/w. This f/w introduces a new
receive mode which allows us to use FreeBSD's physically discontinuous
MJUM9BYTES clusters.
- Switch the driver from chaining MJUMPAGESIZE clusters to using
MJUM9BYTES clusters to avoid mbuf chaining overheads. Due to this
change, people running obsolete f/w images will be limited to an MTU of
PAGE_SIZE - 16.
- Add (disabled by default) support for Large Receive Offload.

adapter list still capable, but only PCI-E adapters are now enabled.
The user can enable older PCI-X or PCI adapters using ifconfig.
Secondly, Arthur Hartwig pointed out my MSI change was not working
correctly, changed to something that now does. Thanks Arthur.
There was also a fundamental bug in the 82575 MSIX code, the MSIX
registers had to be mapped, opps :)

the power_nodriver tunable is off. pci_cfg_save() already checks the
tunable internally, and no other callers of pci_cfg_save() check the
tunable.

- Updated firmware to latest release (v3.4.8) to fix TSO + jumbo frame lockup
- Added MSI (hw.bce.msi_enable) and TSO (hw.bce.tso_enable) sysctls
- Fixed kernel panic when MSI is used and module is unloaded
- Added several new debug routines
- Removed slack space for RX/TX chains since it only covers sloppy coding
- Fixed a potential problem when programming jumbo MTU size in hardware

because on at least my dc based cards there's garbage in there. The
recent changes in the resource code appears to have unmasked this
problem... At least dc now probes/attaches better than it did before.
Also, we no longer need to write to the cfg for the other registers.
legacy codepath match the 82575, without this we were seeing bridging
fail on 82546 adapters. Secondly, I have limited TSO to PCI Express
adapters, I meant to do this and it got dropped in the earlier delta.
Next, I am dropping in the latest shared code from our development
team, consensus was that this should be done frequently, so I am :)

This patch does the following:
- Remove un-necessary code that is not even compiling into the driver
under TW_OSL_NON_DMA_MEM_ALLOC_PER_REQUEST defines.
- Remove bundled firmware image and associated "files" entry for tw_cl_fwimg.c
- Remove bundled firmware flashing routines. We now have tw_update userspace
FreeBSD controller flash utility.
- Fix driver crash on load due to shared interrupt.
- Fix 2 lock leaks for Giant lock.
- Fix CCB leak.
- Add support for 9650SE controllers.
Many thanks to 3Ware/AMCC for continuing to support FreeBSD.
time workaround for problems with 82571 adapters and LAAs, one port
getting reset can cause the other to have its RAR[0] also reset,
thus overwriting an LAA. This fix works around it by also keeping
the address in the last array member.
The other bug is specific to the new 575 adapter, its transmit code
logic in handling hwassists was too crude, it broken when doing
bridges. I am much happier with the new logic,we may want to change
the legacy path at some point to something similar.

- Update to latest (1.4.17) firmware.
- Use the new MXGEFW_CMD_UNALIGNED_TEST (added in firmare 1.4.16) to
have the firmware tell us if the PCIe chipset supports aligned PCIe
completions.
- Hard to maintain, and frequently out of date whitelist of PCIe
chipsets known to produce aligned completions removed, as it has been
replaced in its role of selecting the correct firmware to run by the
use of MXGEFW_CMD_UNALIGNED_TEST.
- Break the dma test out of mxge_reset() and into its own function
(mxge_dma_test()) so it can be used by both the normal DMA test, and
to run the unaligned test.
- Improved support for enabling ECRCs
