Revert r330897:

This was intended to be a non-functional change. It wasn't. The commit
message was thus wrong. In addition it broke arm, and merged crypto
related code.

Revert with prejudice.

This revert skips files touched in r316370 since that commit was since
MFCed. This revert also skips files that require $FreeBSD$ property
changes.

Thank you to those who helped me get out of this mess including but not
limited to gonzo, kevans, rgrimes.

Update mxge firmware to latest available from Myricom.

Update mxge(4) firmware to 1.4.48b (latest available) from Myricom.
Pertinant highlights from Myricom CHANGES file include:

- Make sure invalid external smbus activity cannot affect performance
- Fix to avoid a bug where the link could sometimes stay reported as
up on after unplugging the cable.
- For 8B NIC, make smbus connection passive at init to avoid
possible address conflicts
- Increase number of slices to 17 for multi-slice fw
- Fix a bug where packets dropped because of link_overflow could
be occasionally reported as bad_crc32
- Add selectable failover strategy for dual-port chip: symmetric or primary/backup
- On failover, send RARP broadcast to make the change immediately
known to the network
- Change endianess for PCI Device Serial Number
- For dual-port NICs, time to failover is now a few microsecs
instead of a few millisecs.

Update mxge firmware from 1.4.39 to 1.4.43. Changes include:

- Support for 10G-PCIE*-8B*-C (dual-port CX4) NICs
- For dual-port NICs, f/w failover is now a few microsecs
instead of a few millisecs.
- On failover, f/w sends RARP broadcast to make the change
immediately known to the network
- Fixed a bug observed on IBM X3 architecture where
some spurious ecrc errors would be reported when OS enabled
ecrc support.

Better support for recent Myricom 10GbE NICs

- Update to firmware 1.4.39 for dual-chip NIC (10G-PCIE2-xxx)
support, and SFP+ i2c support

- Identify newer "B" NICs (10G-PCIEx-8B-x) correctly, rather than
mis-identifying them as "A" NICs (cosmetic only)

- Identify the IFM_10G_LRM ifmedia type, where applicable.

- Identify ifmedia types for SFP+ based NICs

- Update copyright

Update to Myri10GE Firmware 1.4.36.

This update fixes a transmit bug in the multi-queue (MSI-X) firmware
which happens when RDMAs complete out of order, and provides
improved support for the new Myri10GE NIC models (10G-PCIE-8Bx)

Update to Myri10GE firmware version 1.4.33 from 1.4.29. Relevant changes include:

- Support for Myricom 10G-PCIE-8B NICs

- multi-slice firmware: fix a bug when the presence of 32-bit or
64-bit DMA addresses for interrupt queues and data is not uniform across
slices.

- Improves automatic selection between ethp_z8e/eth_z8e

Sponsored by: Myricom Inc.

Make the type of the firmware arrays match those
in the other eth*_z8e.h files.

Add optional support to mxge for MSI-X interrupts and multiple receive
queues (which we call slices). The NIC will steer traffic into up to
hw.mxge.max_slices different receive rings based on a configurable
hash type (hw.mxge.rss_hash_type).

Currently the driver defaults to using a single slice, so the default
behavior is unchanged. Also, transmit from non-zero slices is
disabled currently.
