Subject: Re: [PATCH net-next v4] net: virtio_net: notifications coalescing support

Hi Jason,

Before this patch, only ETHTOOL_COALESCE_MAX_FRAMES was supported, now
we support ETHTOOL_COALESCE_USECS as well.

ETHTOOL_COALESCE_USECS is meaningless if VIRTIO_NET_F_NOTF_COAL
feature is not negotiated, so I added the mentioned part.
