skb_page_frag_refill9
Check that a page_frag contains enough room
Usage
bool skb_page_frag_refill(unsigned int sz, struct page_frag * pfrag, gfp_t gfp);
Arguments
sz
minimum size of the fragment we want to get
pfrag

Note
While this allocator tries to use high order pages, there is no guarantee that allocations succeed. Therefore, sz MUST be less or equal than PAGE_SIZE.
