Enable network buffer pool tracking. This means that:

* total size of the pool is calculated

help
|
|
Alignment restriction for network buffers. This is useful for
|
|
some hardware IP with DMA that requires the buffers to be aligned
|
|
to a certain byte boundary, or dealing with cache line restrictions.
|
|
Default value of 0 means the alignment will be the size of a void pointer,
|
|
any other value will force the alignment of a net buffer in bytes.
