Hi team,
we are using "skb = netdev_alloc_skb(NULL, len);" which is getting
failed sometimes for len = 16k.
I suspect mostly system memory got fragmented and hence atomic memory
allocation for 16k is failing, can you please suggest best way to handle
this failure case.
Thanks

If you are handling big frames, then put the data in page size chunks
and use build_skb.
Thank you. Now using alloc_skb_with_frags() with order 0 to allocate the
memory fragments
and skb_store_bits() to store the data to skb from buffer.
