Subject: [net-next 3/3] ice: replace single-element array used for C struct hack
From: Bruce Allan <bruce.w.allan@...el.com>
Convert the pre-C90-extension "C struct hack" method (using a single-
element array at the end of a structure for implementing variable-length
types) to the preferred use of C99 flexible array member.
Additional code cleanups were done near areas affected by this change.
