Subject: virtio-net: fix build error when CONFIG_AVERAGE is not enabled
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=8cabd6a06c01499507e1ff8d641cad656cca613b;p=linux-beck.git

virtio-net: fix build error when CONFIG_AVERAGE is not enabled

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.
