netdev_alloc_skb is failing for 16k length

[Arun Kumar Neelakantam]

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
