6472ac3d8a Mark all SYSCTL_NODEs static that have no corresponding SYSCTL_DECLs.
The SYSCTL_NODE macro defines a list that stores all child-elements of
that node. If there's no SYSCTL_DECL macro anywhere else, there's no
reason why it shouldn't be static.

76dbe6498b - Major reorganization of mbuf handling throughout the driver to
increase robustness (no more calls to panic(9)) and simplify
  code.
- Allocate RX/TX data structures as a single buffer rather than
  an array of 4KB pages to simplify code.
- Fixed LRO (aka TPA) code.  Removed kernel module parameter and
  support enabling disabling LRO through ifconfig(8) command line.
  LRO is still disabled by default but should be enabled for best
  performance on an endpoint device.
- Fixed statistcs code and removed kernel module parameter (stats
  should just work).
- Added many software counters to help identify the cause of some
  performance issues.
- Streamlined adapter internal init/stop code paths.
- Fiddled with debug code (adding some here, removing some there).
- Continued style(9) adjustments.

8fedd5eb65 - Use bus_describe_intr() to describe interrupt usage.
- Use bus_bind_intr() to bind interrupt to a CPU when RSS/TSS is used.
- Use M_DONTWAIT for RSS/TSS buffer allocation.
- Add statistic to track max DRBR queue depth.
- Fix problem in bxe_change_mtu() which referenced the old MTU size
  in a debug print statement.

this driver not using mii(4) in the first place.
