A group is a continuous block of buffer descriptors.
A group covers the maximum configured buffer size and is the allocation size for the buffers to a specific buffer size. If you allocate a buffer to be a specific size, all buffers in the group, if there are more than 1 will also be that size. The number of buffers in a group is a multiple of 2, ie 1, 2, 4, 8, etc.
The number of BD allocated to this group.
This value must be a multiple of 2.
Link the groups on a LRU list if they have no buffers in use.
