* This patch introduces the new SXG_SGL design.
* Related changes to sxg_scatter_gather structure.
* Introduced PSXG_X64_SGL changes which are x64 friendly
* Setting the MAC HEADER pointer properly in skb before giving to higher
layers.

-// The following considerations apply when setting this value:
-// - First, the Sahara card is designed to read the Microsoft SGL structure
-// straight out of host memory. This means that the SGL must reside in
-// shared memory. If the length here is smaller than the SGL for the
-// NET_BUFFER, then NDIS will allocate its own buffer. The buffer
-// that NDIS allocates is not in shared memory, so when this happens,
-// the SGL will need to be copied to a set of SXG_SCATTER_GATHER buffers.
-// In other words.. we don't want this value to be too small.
-// - On the other hand.. we're allocating up to 16k of these things. If
-// we make this too big, we start to consume a ton of memory..
-// At the moment, I'm going to limit the number of SG entries to 150.
-// If each entry maps roughly 4k, then this should cover roughly 600kB
-// NET_BUFFERs. Furthermore, since each entry is 24 bytes, the total
-// SGE portion of the structure consumes 3600 bytes, which should allow
-// the entire SXG_SCATTER_GATHER structure to reside comfortably within
-// a 4k block, providing the remaining fields stay under 500 bytes.
-//
-// So with 150 entries, the SXG_SCATTER_GATHER structure becomes roughly
-// 4k. At 16k of them, that amounts to 64M of shared memory. A ton, but
-// manageable.
