Subject: i40e: add function header for i40e_get_rxfh
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=21675bdc214b34d2ce4e30396e9ff36f0e61ae93;p=linux.git

i40e: add function header for i40e_get_rxfh

Someone left this poor little function naked with no header.  This
dresses it up in a proper function header it deserves.
