SKB setup and free needs to be as light as possible.
Using vectors leads to code like:
for (i = 0; i < MAX_SKB_FRAGS; i++)
Currently, the ZC patches have a fixed frag vector size
(MAX_SKB_FRAGS). But a part of me wants this to be
made dynamic (to handle HIPPI etc. properly) whereas
another part of me doesn't want to do it that way because
it would increase the complexity of paged SKB handling
and add yet another member to the SKB structure.
