Miller" <davem@...emloft.net>, Eric Dumazet <edumazet@...gle.com>, Jakub Kicinski <kuba@...nel.org>, Paolo Abeni <pabeni@...hat.com> Subject: Re: [RFC PATCH net-next v3] net: virtio_net: notifications coalescing support If VIRTIO_NET_F_NOTF_COAL is negotiated, and we try to change the coalescing parameters when the link is up, the control commands will be sent to the device, but the virtnet_set_coalesce function will return -EBUSY anyway. I'll fix it in the next version by checking if the link is up before sending the control commands. BTW, the VirtIO patch was merged, so the next version won't be tagged as RFC.
