Subject: i40e/i40evf: use __GFP_NOWARN
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=dd1a5df872d7889b37b5ce3058a9f2e20d4d8b56;p=linux-beck.git

i40e/i40evf: use __GFP_NOWARN

The i40e and i40evf drivers now cleanly handle allocation
failures and can avoid kernel log spew from the memory allocator
when allocations fail, so set __GFP_NOWARN on Rx buffer alloc.
