Can anyone plz explain me the fields
skb = kmem_cache_alloc(skbuff_head_cache, gfp_mask & ~_ _GFP_DMA);
... ... ...
size = SKB_DATA_ALIGN(size);
data = kmalloc(size + sizeof(struct skb_shared_info), gfp_mask);
It is the simplified version of skb_alloc().

size of data buffer (the bytes you send over the wire not the overhead of
everything you need in ram to process the packets)
> data = kmalloc(size + sizeof(struct skb_shared_info), gfp_mask);
data is the actual buffer (+skb_shared_info at the end of it)
