+ * Parameter set for "convolution" type GEMM.
+ *
+ * For a "convolution" GEMM, the GEMM parameters (M, K) are specified as if
+ * an im2row had been performed on the input tensor to generate the operand
+ * matrix, but instead this structure describes the convolution parameters
+ * such that this can be done on the fly.
+ *
+ * The parameters describe the convolution details - the notional shape of
+ * the input and output tensors, whether padding is to be applied, the size
+ * of the kernel and a constant value to be used for padding (needed for
+ * quantized tensors).
+ *
+ * The second part describes the layout of the input tensor in memory, which
+ * is assumed to be in NHWC format.  This consists of a base pointer and
+ * strides for columns, rows and batches.  'multis' are not supported for
+ * convolution type GEMMs.
