d722cab49a (MFp4) 
- upgrade to reflect state of 1.0.0.86
        - move from firmware rev 3.2 to 4.0.0
        - import driver bits for offload functionality
	- remove binary distribution clause from top level files as it
	  runs counter to the intent of purely supporting the hardware

fa0521c0e9 Make DMA tags per-queue to facilate parallel mappings 
Defer mbuf allocation and initialization until after data has already been
received in a cluster

This reduces cpu utilization somewhat, but it only improves the rx path.
Recent changes to TCP appear to make us rate limited by the TX path.

This is the first step in reducing mbuf management overhead for manipulating
clusters.

77f07749f3 cxgb_stop is only called from cxgb_ioctl so: 
- don't acquire port lock, already held in ioctl
- rename to cxgb_stop_locked
