/*

|
* A few defines are used to control the operation of this driver:
|
|
* USE_ASYNC_IOBDMA
|
|
* Use asynchronous IO access to hardware. This uses Octeon's asynchronous
|
|
* IOBDMAs to issue IO accesses without stalling. Set this to zero
|
|
* to disable this. Note that IOBDMAs require CVMSEG.
|
|
* REUSE_SKBUFFS_WITHOUT_FREE
|
|
* Allows the TX path to free an skbuff into the FPA hardware pool. This
|
|
* can significantly improve performance for forwarding and bridging, but
|
|
* may be somewhat dangerous. Checks are made, but if any buffer is reused
|
|
* without the proper Linux cleanup, the networking stack may have very
|
|
* bizarre bugs.
