Commit ab7db91705e9 ("virtio-net: auto-tune mergeable rx buffer size for improved performance") introduced a virtio-net dependency on EWMA. The inclusion of EWMA is controlled by CONFIG_AVERAGE. Fix build error when CONFIG_AVERAGE is not enabled by adding select AVERAGE to virtio-net's Kconfig entry. Build failure reported using config make ARCH=s390 defconfig.
