openvswitch: Shrink sw_flow_mask by 8 bytes (64-bit) or 4 bytes (32-bit).
We won't normally have a ton of flow masks but using a size_t to store values no bigger than sizeof(struct sw_flow_key) seems excessive. This reduces sw_flow_key_range and sw_flow_mask by 4 bytes on 32-bit systems. On 64-bit systems it shrinks sw_flow_key_range by 12 bytes but sw_flow_mask only by 8 bytes due to padding. Compile tested only. Signed-off-by: Ben Pfaff <blp@nicira.com> Acked-by: Andy Zhou <azhou@nicira.com> Signed-off-by: Jesse Gross <jesse@nicira.com>
