Subject: [net-next 2/3] ice: avoid unnecessary single-member variable-length structs
From: Bruce Allan <bruce.w.allan@...el.com>
There are a number of structures that consist of a one-element array as the
only struct member. Some of those are unused so remove them. Others are
used to index into a buffer/array consisting of a variable number of a
different data or structure type. Those are unnecessary since we can use
simple pointer arithmetic or index directly into the buffer to access
individual elements of the buffer/array.
Additional code cleanups were done near areas affected by this change.
