Subject: [PATCH net-next 01/14] ice: re-order ice_mbx_reset_snapshot function
From: Jacob Keller <jacob.e.keller@...el.com>
A future change is going to refactor the VF mailbox overflow detection
logic, including modifying ice_mbx_reset_snapshot and its callers. To make
this change easier to review, first move the ice_mbx_reset_snapshot
function higher in the ice_vf_mbx.c file.
